Many jurisdictions in North America use a “mitigation sequence” to protect wetlands: First, avoid impacts; second, minimize unavoidable impacts; and third, compensate for irreducible impacts through the use of wetland restoration, enhancement, creation, or protection. Despite the continued reliance on this sequence in wetland decision-making, there is broad agreement among scholars, scientists, policymakers, regulators, and the regulated community that the first and most important step in the mitigation sequence, avoidance, is ignored more often than it is implemented. This paper draws on literature published between 1989 and 2010, as well as 33 semi-structured, key-informant interviews carried out in 2009 and 2010 with actors intimately involved with wetland policy in Alberta, Canada, to address key reasons why “avoidance” as a policy directive is seldom effective. Five key factors emerged from the literature, and were supported by interview data, as being central to the failure of decision-makers to prioritize wetland avoidance and minimization above compensation in the mitigation sequence: (1) a lack of agreement on what constitutes avoidance; (2) current approaches to land-use planning do not identify high-priority wetlands in advance of development; (3) wetlands are economically undervalued; (4) there is a “techno-arrogance” associated with wetland creation and restoration that results in increased wetland loss, and; (5) compensation requirements are inadequately enforced. Largely untested but proactive ways to re-institute avoidance as a workable option in wetland management include: watershed-based planning; comprehensive economic and social valuation of wetlands; and long-term citizen-based monitoring schemes.

Many jurisdictions in North America use a “mitigation sequence” to protect wetlands: First, avoid impacts; second, minimize unavoidable impacts; and third, compensate for irreducible impacts through the use of wetland restoration, enhancement, creation, or protection. Despite the continued reliance on this sequence in wetland decision making, there is broad agreement among scholars, scientists, policymakers, regulators, and the regulated community that the first and most important step in the mitigation sequence, avoidance, is ignored more often than it is implemented (Burgin 2010; ELI 2009; Hough and Robertson 2009; Murphy et al. 2009a). While many studies have shown that compensatory laws and policies have not been effective in maintaining wetland area and function (for example, Spieles 2005; Cole and Shafer 2002; NRC 2001; Malakoff 1998; Roberts 1993; Zedler 1996), and often have unintended social impacts (see BenDor et al. 2008; BenDor et al. 2007; Ruhl and Salzman 2006), few explicate why these laws and policies have failed, or suggest alternative approaches to regulating and managing wetland impacts.
Toward that end, the key objective of this paper is to summarize research explaining why wetland avoidance is commonly overlooked in the permitting process, and to advance what we consider to be key policy modifications or alternatives to incentivize wetland avoidance as a workable alternative to compensation. By critically examining factors that influence wetland permitting decisions, improvements can be made to wetland law, regulation, and policy such that losses can be prevented, rather than following the heretofore pattern of permitting losses and hoping that compensation will replace lost wetland area, values, and functions.
While there are many countries worldwide that have made strides in wetland regulation, we have limited our examination of wetland law, regulation, and policy to the United States and Canada, and specifically the province of Alberta. As carried out in other environmental policy and conservation strategy evaluation studies (e.g., Reed 2008; Lovell and Sullivan 2006; Brooks et al. 2005), we conducted a web-based search of wetland management literature from peer-reviewed sources and widely available grey literature published between 1989 and 2010. Articles were located using search engines such as ISI Web of Knowledge, JSTOR, Web of Science, and Google Scholar, using keyword search terms such as: wetland, plan, success, assessment, avoidance, compensation. This work was also informed by 33 semi-structured, key-informant interviews conducted in Alberta between 2009 and 2010. Key informants were asked questions about the effectiveness of the existing wetland policy and the sample consisted of regulators, agency decision-makers, scientists, industry representatives, and consultants who were intimately familiar with the policy. This sociological methodological approach has been applied previously in the evaluation of wetland policy implementation in Louisiana (Krogman 1999). Interviews were conducted until saturation was reached, i.e., no new arguments were advanced among respondents (Krogman 1996), and all interviews were recorded, transcribed, and coded across themes using the qualitative data analysis software program NVIVO.
Background: wetland regulatory context
Wetland regulation has a long and complex history in the United States, going back to 1972 and the introduction of Section 404 of the Federal Water Pollution Control Act (more commonly known as the Clean Water Act). The principal intent of the Act was to “restore and maintain the biological, chemical, and physical integrity of the Nation’s waters” in part through the establishment of the Section 404 permitting program. This regulatory process requires that an Individual Permit be issued for any activity that results in the discharge of dredged or fill materials into waters of the United States, including wetlands (Hough and Robertson 2009; Chertok and Sinding 2005; Williams and Connolly 2005). Both the Army Corps of Engineers (the Corps) and the Environmental Protection Agency (EPA) were given jurisdiction over the permit program, with the Corps being responsible for overseeing day-to-day permitting activities, and the EPA being given authority (“in conjunction with” the Corps) to develop guidelines for permit approvals, as well as the authority to override any permit approval issued by the Corps (Ellis 2005).
In 1977, amendments were made to the Clean Water Act that allowed the Corps to issue General Permits for activities that resulted in “only minimal adverse environmental harm”.1 These General Permits lacked the more rigorous environmental oversight of Individual Permits (Hough and Robertson 2009; Taylor and Geoffroy 2005), and clearly signaled that the goal of restoring and maintaining the integrity of wetlands was not going to be achieved by simply denying permits and avoiding impacts. Consequently, other regulatory and policy mechanisms began to emerge, and the concept of “mitigating” the damage to wetlands through impact minimization or compensation began to gain traction as an alternative to wetland avoidance (Hough and Robertson 2009; Kruczynski 1990).
In 1980, the Section 404(b)(1) Guidelines were released, putting new restrictions on the discharge of dredged and fill materials and formalizing the concept of “sequencing” wetland permit decision-making. Under Section 230.10 (a–d) of the Guidelines, a permittee must demonstrate that there is no other available, feasible, or environmentally preferable alternative to the proposed project: the so-called least environmentally damaging practicable alternative (LEDPA) analysis (Pifher 2005). While these regulations formally prioritize wetland avoidance over impact minimization and compensation, permittees can argue that there are no other “practicable alternatives” to the proposed project by citing limitations presented by factors such as land ownership and availability, geographic scope, economic viability, logistics, and/or technological feasibility (Pifher 2005). Further, permittees can define their overall project purpose in a way that effectively makes alternatives to wetland loss impracticable; they can also argue that their project is “water dependent”, or that alternative sites would result in less desirable environmental outcomes (Hough and Robertsen 2009; Pifher 2005). The Corps and the EPA have also acknowledged that there is a need for “flexibility” in the application of the alternatives analysis, given that impacts to wetlands may vary in their extent, severity, and duration (Pifher 2005). Combined, these factors have led to a general failure by both the Corps and EPA to strictly enforce the mitigation sequence as written in the 404(b)(1) Guidelines, and have arguably contributed to the creation of a regulatory culture where “mitigation” and “compensation” are generally seen as being one and the same (Hough and Robertson 2009).
The reliance on compensation over avoidance as a mechanism for achieving wetland management goals was reinforced in 1989, with the adoption of the “no net loss” policy by the Bush administration. While many felt that this new policy elevated the issue of wetland loss in the national consciousness, there was also a recognition that the no net loss goal “was not merely to be achieved through the denial of permits, or even the avoidance and minimization of impacts, but rather through allowing impacts and requiring compensation” (Hough and Robertson 2009, p. 26). As the use of wetland compensation grew throughout the 1990s, there was mounting pressure from industry to move away from on-site and in-kind wetland mitigation, and towards the use of wetland mitigation banking as a market mechanism that would allow for the increasing use of off-site compensation (Ruhl et al. 2009; Salzman and Ruhl 2005). This approach to wetland compensation was seen by government agencies to “ensure wetlands conservation at minimum economic and political cost” (Salzman and Ruhl 2005, p. 2), and by 2005 wetland banking had grown to account for as much as 30% of all mitigation being carried out in the US (Wilkinson and Thompson 2006). The increasing use of wetland banking as a form of permittee-responsible mitigation drove the need for clearer and more consistent standards and procedures. As a result, the Corps and the EPA jointly issued new rules for wetland mitigation in April of 2008. Though designed to improve compensation outcomes by creating clear performance standards and administrative procedures, concerns have emerged that the procedures outlined in the new rule will become yet another regulatory mechanism that further institutionalizes the use of compensation over avoidance (Stokstad 2008). Given that less than one percent of permits in the US are denied by the Corps (Murphy et al. 2009b), and the general assumption by proponents that they will not be denied a permit (Nichols 2008), it seems apparent that compensation, over avoidance or minimization, has become the preferred mechanism by which to achieve the goal of no net loss in the United States (Hough and Robertson 2009; Race and Fonseca 1996; Kruczynski 1990).
Wetland management and regulation in Canada has a much shorter history than that of the United States, and wetland policy in many Canadian jurisdictions is either non-existent or is in early stages of development (Rubec and Hanson 2008). One exception to this is Alberta, where the trajectory of wetland policy can be said to resemble that of the United States, particularly with respect the growing trend towards the use of compensation over avoidance as a mechanism to meet wetlands policy goals.
In 1993, Alberta introduced a regional wetland policy that primarily applied to marsh wetlands in the settled areas of the province. While the stated policy goal is to “sustain the social, economic, and environmental benefits that functioning wetlands provide, now and in the future” (AWRC 1993), the implementation of the policy has focused on achieving a no net loss of wetland area through conserving wetlands in a natural state, mitigating the degradation or loss as close to the site as possible, and enhancing, restoring, or creating wetlands in areas where they have been depleted or degraded (Rubec and Hanson 2008; AWRC 1993). While Alberta was one of the first provinces in Canada to adopt a wetland policy, very little progress was made with respect to implementation of the policy until December of 1999, when the outdated Water Resources Act was replaced by the Water Act. This new legislation shifted the focus away from solely regulating the allocation of water, and instead included a more comprehensive purpose for supporting and promoting the “conservation and management of water, including the wise allocation and use of water”.2 Under the Act, any activity that “causes, may cause or may become capable of causing an effect on the aquatic environment”3 requires an approval, and in making a decision about granting an approval, the government “may consider any existing, potential or cumulative effects on the aquatic environment”.4 Notwithstanding this more conservation-oriented language, the Purpose of the Act also specifies that decisions about the management of water resources must also recognize “the need for Alberta’s economic growth and prosperity”.5
In fact, many policy actors in Alberta feel that wetland avoidance is simply not a practical option in light of other considerations, such as economics. There is often an acceptance that there is no alternative to filling the wetland and simply compensating for the loss, as summarized by another government approval writer who said:
What we found is that avoidance just doesn’t seem to be an option for most of [the permit applicants] out there. They’ve already planned their project; they know what they want to do. It’s very difficult to work around that. (Approval writer, personal communication, June 2009)
We would want you to avoid the impact whenever and wherever possible, but there is a realization that it’s not practical and development will occur, and so then we have to go to minimize, mitigate, and compensate. (Approval writer, personal communication, August 2009)
The general failure to avoid wetland impacts in both the US and in Alberta, despite this preference being stated in regulation and policy, has led to an overall decline in the number and quality of natural wetlands in many jurisdictions across North America (Dahl and Watmough 2007; Walters and Shrubsole 2005; Zedler and Kercher 2005). It has also spurred a lively debate over whether the mitigation sequence of avoid, minimize, and compensate is an effective approach for managing wetland habitats within a no net loss framework. For example, Burgin (2010) suggests that “the outcome for wetland mitigation may not be an ‘unmitigated disaster’ but it is, at best, modestly successful” (p. 53), and Murphy et al. (2009b) go so far as to say that “mitigation activities continue what can only be described as a ‘cockeyed optimist’ approach to aquatic resources permitting—one that is destined to lead to further deterioration of the nation’s aquatic resource base” (p. 3112). Given that many jurisdictions have adopted the mitigation sequence as a means to achieve a no net loss of wetlands, it is critical that we begin to better understand the key factors that lead to the pervasive tendency to skip-over avoidance.
Key failures in the avoidance of wetlands
A lack of agreement on what constitutes “avoidance”;
Current approaches to land use planning do not identify and prioritize wetlands in advance of development;
Wetlands are economically undervalued;
A “techno-arrogance” is associated with wetland creation and restoration, resulting in increased wetland loss;
Requirements for compensation are inadequately enforced.
A lack of agreement on what constitutes “avoidance”
Foremost on the list of problems associated with the wetland mitigation sequence is the absence of a clear understanding on what constitutes “avoidance”, and a lack of standardized methods or guidelines for evaluating or interpreting this regulatory requirement (ELI 2009; Yocom et al. 1989). While the regulatory understanding around wetland mitigation in the US has historically included a sequencing of “avoid, minimize, and compensate”, these words were never expressly written into US regulation until the Final Rule on Compensatory Mitigation for Losses of Aquatic Resources was issued in April of 2008. Prior to that, the concept of wetland mitigation was only vaguely defined as a sequence of decisions that make up the alternatives analysis, which was further clarified in a Memorandum of Agreement between the Corps and the EPA in 1990. A critical component of the alternatives analysis is how the proponent has defined the basic project purpose, and whether the regulator accepts the project purpose as presented. While the regulator is not obligated to accept the basic project purpose as proposed by the permittee, this step alone has the potential to foreclose on any opportunity to avoid wetland impacts; if the purpose has been too narrowly defined, alternatives may be considered impracticable (Pifher 2005). The language that allows compensation if avoidance or minimization “is not practicable” becomes a de facto loophole in its non-specificity, allowing developers to skirt the intent of the law and move directly to compensation. Given that there is no rigorous and repeatable process under which to consider “practicability” (Murphy et al. 2009a), the availability of options other than avoidance, such as compensation, are too easily considered by regulators. For example, in the US, Krogman (1999) found that administrative momentum, or the implicit assumption that regulators need to find a way to make it work for the applicant, makes asking the permit applicant to consider other sites for development seemingly unreasonable.
Once there is agreement on the basic project purpose and the proponent has demonstrated there is no other practicable alternative in terms of project location, there is still a requirement under Section 230.10 of the 404(b)(1) Guidelines to make the on-site impacts to the wetland as small and innocuous as possible, including giving consideration to how the project can be designed to avoid or minimize impacts (Hough and Robertson 2009). In this step there is additional confusion over the meaning of avoidance; to some regulators on-site avoidance means preventing direct impacts, such as placing fill material directly into a wetland. To other regulators, “an attempt constitutes avoidance” (ELI 2009, p. 3), meaning that any effort to modify a project—regardless of whether the project ultimately results in a direct impact—is considered avoidance. The language around the “minimization” of wetland impacts is also sufficiently vague, and in many cases, avoidance and minimization are lumped together such that “any measures to reduce impacts usually are applied to satisfy both requirements” (ELI 2009, p. 6).
Given the lack of clarity around what constitutes avoidance and minimization, in addition to an absence of clear standards or guidelines, wetland permit decisions in both the US and Alberta are subject to a high degree of subjective interpretation by regulators. This leads to an approval process that is characterized by inconsistent decision-making and uncertainty within and between jurisdictions (ELI 2009). In Alberta, one regulator is quoted as saying:
[The mitigation sequence] is more of a mechanism for enabling [wetlands] to be disturbed. We don’t really have a good mechanism of saying, ‘When should we say no?’ If you have a sensitive vegetation species, should we be saying no? If there’s sensitive wildlife, should it be no? We don’t have clear guidelines on that. (Approval writer, personal communication, August 2009)
Consistency is an issue…and personally, I think it looks bad in the department. We should [have] a standard approach. Maybe you have different flavors from different offices, but the requirement…and the expectations should be the same across the board (Approval writer, personal communication, August 2009)
In most cases, the “best outcome” does not include the avoidance of wetland impacts, but rather, approval of development plans and permit conditions that are palatable and acceptable to the applicant, which most often includes wetland compensation (Nichols 2008).
Well, there’s always the ability to say no. Do we say no very often? Not really. What we try to achieve is the best outcome. (Approval writer, personal communication, June 2009)
Poor planning in advance of development
A clear understanding of the adverse impacts caused by urban development and resource degradation can assist planners in mitigating loss of ecosystem structure and function. When incorporated into a planning process and final plan, this information communicates the importance of protecting wetland function and integrity at the watershed level (p. 173).
This sentiment was echoed by a government employee who said:
If there [are] areas of wetlands that are significant, well then if we know that up front, we wouldn’t go out and purchase them and try to develop them. (Sr. Executive, Land Development Company, personal communication, June 2009)
I think the [wetland protection and conservation] debate needs to be taken up to a land use discussion to talk about what areas of wetlands do we want to preserve? Where should we keep them, where should we not? Where is it okay to develop, where is it not? It’s a broader context, and I find that our [wetland approval] process tends to get leveraged a little bit in those discussions. (Approval writer, personal communication, August 2009)
Despite the existence of available technologies to assist in the prioritization of wetlands for protection, such as GIS-based synoptic land cover maps, rapid ground-based assessments, and intensive field assessments (Brooks et al. 2004), many land use planners do not prioritize significant wetlands or wetland communities. The failure to prioritize is often due to limited wetland mapping, inadequate wetland assessment methodologies, and poor linkages between wetland management actions and outcomes (LaPeyre et al. 2001). The result is that rare, unique, or high-value wetlands are treated with the same regard as common or low-quality wetlands, and few barriers to their loss have been brought to bear, contributing to persistent and incremental losses of wetlands. Murphy et al. (2009a) concurs, suggesting that even new and stricter rules that favor wetland avoidance in the United States “allow for a project-by-project analysis of mitigation that need not look at the entire watershed and its needs” (p. 15).
Ambiguous and competing goals within and between government agencies can also contribute to the lack of prioritization and planning in wetland regulation and management at various scales. Without clear goals for maintaining wetland ecosystem function or protecting wetlands that are highly valued socially, simple rules of minimizing harm and trading-off one wetland for another has become the norm (Mann and Goldman-Carter 2008; Ehrenfeld 2000). An Alberta example of this shows that land use planning and regulatory decisions are made at different scales by multiple governments and agencies, including: municipalities for land-use zoning and bylaws; Alberta Energy for mineral rights; Alberta Sustainable Resource Development for forest resources and public lands; Alberta Environment for water and air; and Fisheries and Oceans Canada for fish and fish habitat. To further complicate matters, wetland policy implementation varies between the white zone (the southern one third of the province that is mostly private land and dominated by agricultural land use) where wetland impacts are regulated by an interim wetland policy, and the green zone (the northern two thirds of province comprised primarily of publicly owned forested lands) where the interim policy does not currently apply. This fragmentation of decision-making and general failure to better integrate planning at multiple scales has contributed to the ineffectiveness of the wetland policy in Alberta.
Divergent goals for wetland management can also occur between regulators and restoration service providers (ELI 2006). In this case, the intention of (or task assigned to) the restoration service provider is to meet a specified goal or set of minimum criteria to ensure, for example, a no net loss of wetland area, even if the compensatory wetland is not of the same replacement value as the wetland that was lost. Indeed, many in-lieu fee programs in both Alberta (personal communication, August 2009) and the US (ELI 2006) allow restoration service providers to accept wetland compensation funds before mitigation sites are even identified or secured. There are also concerns in Alberta that without more coordinated planning, wetlands that have been restored or avoided will remain vulnerable to future incursions, particularly in areas where adjacent land values rise substantially, as they have in the more urbanized southern portion of the province and in northeastern Alberta where oil sands production is the dominant industry.
Reconciling this pluralism of goals at multiple scales of planning is a significant challenge in the management of wetlands across jurisdictions, and has been described by Huppes and Midden (1991) as a great social dilemma in wetland policy. Finding a balance between site-specific decision-making that focuses on the management of a single wetland, versus adopting a broader and more regional approach to wetland permit decisions, requires a fundamental (and likely structural) change in how wetlands are regulated. As Huppes and Midden (1991) suggest, “it is not so much individual projects that have to be improved, on an ad-hoc basis, but the overall development strategy” (p. 204); thus, the current approach in the US and Alberta of simply focusing on wetland impacts, permitting, and compensation at the project-level needs to be re-evaluated. Providing more clarity around the most appropriate scale (or scales) at which the alternatives analysis, and thus avoidance, should be applied would go a long way in resolving some of these issues in the US. In Alberta, the introduction of regulation that requires both a site-specific and a regional evaluation of impacts would contribute towards a more ecologically relevant approach to wetland management.
As a caveat, land use planning at the watershed level is not an answer in and of itself for integrating broader wetland values into permitting decisions. Throughout the land use planning literature are examples of plans and policies that have been adopted with little or no attempt to measure progress toward achieving stated goals and objectives (Wenig 2006; Seasons 2003; Baer 1997). Brody and Highfield (2005) summarized a host of studies and concluded that far more effort is put into planning than is accorded to the details of implementation. Similarly, in Alberta, there have been a number of elaborate land use planning efforts that have not resulted in measurable land use changes, such as new regulations and prioritized land uses (Wenig 2010; Fluet and Krogman 2009). Following through with effective implementation of land use planning and wetland prioritization is as important as the process of planning itself, and requires sufficient allocation of resources (e.g., financial and personnel) to be successful.
Wetlands are economically undervalued
The inexorable demand for developable land has resulted in the emergence of market-based mechanisms that have re-focused the discussion away from avoiding and minimizing wetland impacts, towards a more permissive orientation that allows for the “exchange” of wetland area or function between impact and compensation sites. The emergence of wetland banking and in-lieu fee payments has, in part, been driven by the perception that wetland avoidance in areas of economic conflict, such as residential subdivisions, is impracticable because the “assumed” value of wetlands is often much lower than the more immediate and tangible wealth generated by development. While accounting tools for ecosystem services do exist, they are complex (Moeltner and Woodward 2009) and are employed by relatively few specialized resource economists; consequently, the substantial economic value that flows from wetlands in the form of ecosystem goods and services (Moeltner and Woodward 2009; Costanza et al. 2008; Birol and Cox 2007; Boyer and Polasky 2004; Turner et al. 2000; Mitsch and Wilson 1996) is rarely considered in the permitting process.
You really have to dig at the avoidance and mitigation piece…a lot of proponents, especially in the land development side of things, they just want to skip right to, “Let’s write a cheque”. (Approval writer, personal communication, August 2009)
Robertson and Hayden (2008) have also reported a trend in the Chicago region where mitigation banks are frequently located in areas where land value prices are considerably lower than at the site of impact. This arguably creates a large subsidy for industry and land developers who are able to buy credits in a wetland bank for far less money than they receive when their product is sold in the marketplace. While private interests gain considerably in this arrangement, the public largely pays this subsidy in the form of lost ecosystem goods and services (de Groot et al. 2010; Mitsch and Gosselink 2000), and there are often unanticipated social costs associated with the redistribution of wetlands through the use of compensation (BenDor et al. 2008; BenDor et al. 2007).
The controlling factor for wetlands in the province, even though the water is provincial jurisdiction, [is that] the ownership of that land is private…if you could just go out and rebuild [wetlands] wherever you wanted it’d be real easy to do, but unfortunately they have to have approval from those landowners. (Wetland restoration agency employee, personal communication, August 2009)
The reliance on wetland banking or in-lieu fee payments as a mechanism to replace wetlands assumes that the values, functions, and services provided by the compensatory wetland are in some way equivalent to those that were lost, and are thus fungible (items freely interchangeable with another to satisfy an obligation). Where wetlands are assumed to be fungible, trade in these wetlands grows and the demand for comparability emerges. In Alberta, all of the government regulators we interviewed indicated that the most common metric used for comparability or equivalency between impacted and compensatory wetlands is area, with very little consideration given to wetland functions or services. Wetlands have thus become a commodity in a market where the measure of comparability between the items being exchanged disregards ecological and social values and functions. As many other scholars have argued, wetlands vary considerably in their value and function by type, landscape context, and spatial scale (de Groot et al. 2010; Hein et al. 2006; Mitsch and Gosselink 2000); therefore, it is difficult to meet the goal of maintaining the biological, physical, and chemical integrity of wetlands in a market where area is the only criteria used to assess comparability.
“Techno-arrogance” associated with wetland creation and restoration results in increased wetland loss
We have to come up with a new scenario where we actually can recreate [the wetland]. The outline of that wetland is the same as it is in a natural state, but it’ll be in an urban environment and fed [by] storm water through a pipe, and it’ll be much better, at least aesthetically, than it is today. (Sr. Executive of a land development company, personal communication, August 2009)
The idea that a constructed wetland that visually resembles a natural wetland is adequate compensation ignores that wetlands grow and develop according to a myriad of highly variable inputs over time, including stochastic weather, random arrival events of species, competition, surface and groundwater interactions, and many others. The fluctuations and interactions of wetland ecosystems are more akin to human metabolism than they are to an automotive engine, with dynamic interacting components such as wetland soils, hydrologic regimes, riparian zones, and water chemistry that are linked to their surroundings. Constructed wetlands must grow, mature, and evolve, often requiring decades to centuries to stabilize and broadly resemble naturally occurring wetlands. Such time frames are rarely considered in the price of compensation.
Despite the complexity of wetland ecosystems, optimistic and naive land developers, economists, engineers, and policy makers often argue for compensation over avoidance, confident in the notion that constructed wetlands can adequately replace the values and functions of a natural wetland. The lack of focus on wetland avoidance allows for engineered compensatory wetlands to receive more political and economic value than their natural counterparts, as they provide decision-makers the options, flexibility, and negotiation room beyond a hard and fast requirement to relocate the proposed development to a non-wetland site. The premise of compensatory offset wetland policies is that habitat loss can be mitigated through the creation or restoration of habitat that is equivalent to that which was lost. The challenges associated with measuring, let alone reproducing, the full suite of ecological, social, and economic values and functions of a natural wetland makes the reliance on this policy approach untenable in all cases, and highlights the need to give greater consideration to avoidance in the mitigation sequence.
Inadequate enforcement and compliance of wetland law and policy
There is a large segment of the [agricultural] producer population that doesn’t understand that bodies of water are crown land. [The wetland is] on their land, it’s surrounded by [their land] – it must be theirs. (Alberta Government employee, personal communication, May 2010)
While there are clearly enforcement problems in many jurisdictions, there is also a growing need for “back-end” monitoring to ensure that compensation sites are performing adequately and are meeting the conditions set out in the permit. The list of studies documenting non-compliance in the United States is long (for example, see Reiss et al. 2009; Brown and Veneman 2001; Turner et al. 2001; Zedler and Callaway 1999), and clearly articulate the general failure of permit holders to replace wetland functions through off-site compensation (Burgin 2010; Cole and Shafer 2002; Malakoff 1998; Roberts 1993; Spieles 2005; Zedler 1996). The lack of government oversight to follow-up and ensure that the conditions of approvals for wetland losses are met over an appropriate timeframe reinforces the preference for compensation over avoidance; if permit holders are not held accountable, then compensation is much easier and economical than avoidance.
There are many recorded failures to meet the ecological conditions stipulated in wetland permits, yet few studies have examined why regulatory compliance has been so weak. One such study, conducted by the United States Government Accountability Office (GAO 2005), highlighted a number of major shortcomings of the regulatory process, including a general reluctance by the regulators to sanction violators, preferring instead to rely on negotiation to resolve the contravention. In many cases, legal recourse for non-compliance was not an option, as the conditions of the permits were not specific enough to allow for enforcement action against the violator, harkening back to the simple and vague language mentioned earlier.
This reactive, rather than proactive, approach to wetland regulation in Alberta appears to be related, at least in part, to a lack of government capacity and resources, as expressed by another approval writer who said:
The department is really good at issuing the approvals and doing the up-front work … we’re not as good as following up with the monitoring and the back-end stuff, just because you get busy with the next project. There’s always something coming up, the next fire to manage. (Approval writer, personal communication, August 2009)
I think we need to be more proactive, and probably any person that you talk to would agree with that statement – that the government needs to be proactive, but it’s a matter of resources … it’s pretty obvious to me that we’re somewhat understaffed in terms of our ability to deal with some of these approval situations, and probably even more so in the enforcement and compliance end of things where we just don’t have the capacity to be proactive. We’re a reactive organization right now. (Approval writer, personal communication, June 2009)
Some authorities claim that increased oversight by regulatory agencies, such as more frequent interaction with permit holders, regular site visits, and more frequent enforcement actions, could improve compliance outcomes (Reiss et al. 2009; Schulte-Hostedde et al. 2007; NRC 2001). More rigorous record keeping (Minns et al. 1996; Kentula et al. 1992) and better coordination of policy within and between jurisdictions and agencies responsible for wetland permitting (Austen and Hanson 2007; Race and Fonseca 1996) have also been suggested as a means for achieving better compliance. By improving compliance, not only would outcomes for compensatory habitat creation be improved, it may act as an adequate deterrent if the costs associated with meeting compensation requirements outweighed those of avoiding the wetland in the first place.
Alternatives to address key failures in wetland avoidance
To address the key failures in wetland avoidance described above, we recommend experimenting with a suite of policy tools, some of which are already in place in select jurisdictions, which would better link avoidance mechanisms with land use planning and regulation. Below we provide some thoughtful, though mostly untested, considerations for re-instituting avoidance as a workable option in wetland management, including: watershed-based planning; more comprehensive economic and social valuation of wetlands; and long-term citizen-based monitoring schemes.
By placing wetlands within a broader landscape context, watershed planning can help to prioritize the conservation of high value wetlands, or identify land uses that may not be compatible with regional wetland conservation goals (Chavan et al. 2008; Brooks et al. 2006; Stein and Ambrose 1998). Using science-informed watershed plans, wetlands can be managed within a larger hydrologic and ecologic regime that considers issues of water quantity and quality, habitat connectivity, and biodiversity in all of its complexity (NRC 2001; Margules and Pressey 2000).
A preference for on-site or in-kind mitigation should not be automatic, but should follow from an analytically based assessment of the wetland needs in the watershed and the potential for the compensatory wetland to persist over time.
A powerful science-based decision support tool that can be utilized for conservation planning at the watershed scale is systematic conservation planning (SCP). Systematic conservation planning is a rigorous, transparent, and repeatable framework that attempts to reduce the “uninformed opportunism” of traditional conservation planning by integrating multiple criteria (e.g., ecological, sociopolitical, economic) into broader landscape planning and decision-making (Pressey and Bottrill 2008; Sarkar et al. 2006; Margules and Pressey 2000). The framework for systematic conservation planning generally consists of several key steps (Groves 2003; Margules and Pressey 2000): setting conservation goals; identification of conservation criteria; development of a conservation strategy; identification of conservation areas; implementation and prioritization; and finally, monitoring and management. By utilizing this framework and systematically identifying wetland conservation criteria—the elements of biological and physical diversity that will be the focus of planning efforts—meaningful conservation goals can be set within a watershed, and priorities for wetland conservation, protection, or alternative management approaches can be identified in advance of development.
One key strength of SCP is the potential to involve local resource users and other key social actors at various stages in the process, including setting conservation goals, developing criteria and management strategies, and monitoring outcomes (Sarkar et al. 2006; Pierce et al. 2005; Cowling and Pressey 2003). Through SCP, local and regional conservation plans can be tailored to reflect the local context, allowing for the inclusion of a wide variety of perspectives and values in the planning process. The resulting user-friendly and target-driven planning tools that are the products of SCP can be used by authorities at various jurisdictional levels, from municipal to regional, to help inform land use planning and decision-making (Pierce et al. 2005). Wetlands can thus be framed in both time and place by iteratively and adaptively identifying future land use pressures and potential risks, thereby allowing for a greater emphasis being placed on the avoidance of wetlands that have been identified as being high-priority for management.
More comprehensive watershed-based planning also allows for the development and use of region-specific wetland functionality indicators that can be derived through the use of benchmark or reference sites. Matthews and Endress (2008) suggested that the use of benchmarks could help agencies with permit approvals, selection of mitigation site locations, calculation of compensation ratios, development of performance criteria, and implementation of post-construction monitoring protocols. Bedford (1999) argued that wetland restoration will be more successful if individual wetland restoration decisions are made in light of past and present regional profiles, and Olsen and Christie (2000) highlighted the importance of locally and socially relevant indicators to build local ownership of coastal (wetland) management, especially for direct users/abutters of wetlands. Watershed planning can also provide rich opportunities for more place-based and prescriptive restoration goals (Stanturf et al. 2001; Olsen and Christie 2000), thereby addressing some of the competing goals (individual to structural) that limit overall restoration effectiveness.
As landscape-level approaches to wetland management replace previous command-and-control style regulations, planners among different levels of government will need to coordinate carefully (BenDor and Doyle 2010), particularly in areas where watershed plans cross jurisdictional boundaries. The coordination required for watershed management can help clarify jurisdictional issues and uncertainties (ELI 2009), and improve interagency communication (Olsen and Christie 2000). While BenDor et al. (2007) found tension between local authorities as watershed-based management proponents, such tension was not necessarily disadvantageous, as it provided an avenue to help local and extra-local stakeholders more clearly articulate goals for restoration projects. Ehrenfeld (2000, p. 2) acknowledged such tension as an important component of projects because it “sets expectations, drives the detailed plans for actions, and determines the kind and extent of post-project monitoring”.
Globally, climate change poses considerable threats to wetlands due to forecasted changes in hydrological regimes (Johnson et al. 2010; Acreman et al. 2009). As climate change planning is increasingly incorporated into natural resource management, watershed-based planning offers an effective mechanism in which to accommodate the impacts of climate change on wetlands (Erwin 2009; Simenstad et al. 2006). In certain parts of the world where climate change begins to negatively impact water resources, the water storage, filtration, carbon sequestration, biodiversity maintenance, and other ecological goods and services offered by wetlands will become increasingly valuable. Thus, watershed planning will allow for more accurate assessments of a region’s vulnerability to climate change-related risks, such as drought (Hurd et al. 1999), and will be an important tool for assigning priority for the management of high-value wetlands.
In making this recommendation we acknowledge that this approach is not novel, and has previously been applied in some jurisdictions in one form or another, with varying degrees of success. For example, the US Environmental Protection Agency has an Advanced Identification (ADID) planning program that identifies wetlands that are “suitable or unsuitable for the discharge of dredged and fill materials”, with the intent of providing local communities with “information to help them better understand the values and functions of wetlands in their areas” (EPA 2009). While this approach has merit, the program is not widespread and is not mandatory; thus, it is likely of limited use in planning and management at large scales. The concept of watershed planning also confronts tensions over the management of common pool resources on private property. This conflict is very real and presents itself as a significant challenge in the development and implementation of any watershed plan. For example, Ando and Getzner (2006) examined the role of land ownership in wetland conservation decisions in Australia, and found that wetlands were more likely to be protected on public versus private lands, and concluded “ownership status is a significant factor in the pattern of wetland conservation” (p. 302). While land ownership issues are a barrier to watershed-level planning and conservation, there is an emergence of new policy tools that may offer some opportunities in this regard, including biodiversity off-sets (ten Kate et al. 2004), transfer of development credits (Pruetz 2009), and reverse auctions (Packman 2010), to name only a few. Whether these tools are able to overcome the challenges of managing wetlands on private property remains to be seen.
More comprehensive ecological and social valuation of wetlands
Making informed decisions about the economic trade-offs associated with a given permit application are difficult for both developers and wetland regulators because the ecological, social, and economic values of wetlands are difficult to identify, combine, compare, value, and aggregate, resulting in a chronic undervaluation of wetland habitats (Costanza et al. 2008; Carlsson et al. 2003; Turner et al. 2000). Under current accounting practices and market orientation, the economic value of land adjacent to a wetland often exceeds the “assumed” value of the wetland itself, which leads to the belief that wetland avoidance is an impracticable economic option. This tendency to perceive wetlands as economic liabilities may be overcome if ecosystem services and social values were accounted for in permit and planning processes. Incorporating economic and social valuation processes into wetland permit approvals may help link the desired ecosystem goods and services to benefit cost analyses of areas being considered for development. In turn, increased economic values attached to those broader ecosystem and other non-market services (e.g., aesthetics, recreation, education) may provide disincentives to wetland development and help to focus development in non-wetland areas. By including environmental and social considerations in the accounting standards under which wetland regulators and land developers make their decisions, the notion of wetland compensation takes on a new meaning. It becomes much more costly to compensate for wetlands loss when the “true cost” of that loss is borne by the permittee, rather than the public.
Long-term citizen-based monitoring schemes
One of the reasons identified for the policy failure of wetland avoidance is inadequate enforcement of compensation requirements. This lack of enforcement can occur because of shrinking budgets for enforcement personnel, or it may be due to a deficiency in the quality or quantity of information available to enforce regulations, such as inadequate assessment or monitoring data. If wetland regulators do not have reliable data on the performance of natural, reclaimed, or constructed wetlands, it becomes very difficult to make evidence-based land use planning decisions. At the same time, environmental policy in North America is experiencing a move away from command-and-control style management towards self-enforcing market-based policies (Daley 2007), and increasingly towards resilience management such as adaptive co-management, networked, or collaborative environmental governance (Armitage 2008; Reed 2008).
One type of program that has strong potential in this emergent policy space is the use of long-term, citizen-based monitoring schemes to help manage local wetlands. These schemes would not only encourage local stewardship of wetlands, but would also provide data to help regulators gauge approval compliance, potentially resulting in improved environmental outcomes. For example, citizens have been trained to identify functional and structural characteristics of wetlands, and report on these measures in a consistent, reliable manner, at low cost to local institutions (Koontz and Thomas 2006). Inherent to this program might be an empirical expression of human valuation and appreciation for the wetlands, giving greater opportunity to measure the intangible social value of these habitats. With this new data and more engaged local citizens, it is more likely that wetlands will be avoided during development, as compared to decisions that are made in the absence of data and a locally organized wetland group. The inadvertent creation of local political will and interest in wetlands may be an antidote to public apathy, resulting in more careful scrutiny of development plans and the elevation of avoidance as the key policy activity for wetlands protection.
While the use of citizen scientists is a relatively recent phenomenon, citizens are increasingly being included in conservation and restoration planning (Currin et al. 2008; Oscarson and Calhoun 2007) and have been found to be effective assistants to local land managers (Sharpe and Conrad 2006). If a standard protocol is used (e.g., Christmas Bird Count), a diverse public can be used as a local resource that is capable of collecting data on both wetland structure and function (Currin et al. 2008). By utilizing citizen participation, not only are costs lowered compared to traditional data collection methods, but local stewardship is also promoted, with local communities benefiting directly from the educational value of participation (Hudson 2001). The outcome may be a more engaged and informed citizenry that can bring political pressure to bear on the issues of wetland conservation, making wetland avoidance a more practicable option from a sociopolitical perspective. For example, Meyer and Konisky (2007) found that local environmental institutions that have included a broad array of community-based efforts to increase local participation in environmental decision making, particularly though local bylaws that protect wetlands, outperform jurisdictions that lack similar bylaws on numerous wetland measures.
Wetland avoidance needs to be reinstituted as the first, and most preferred option for wetland management in jurisdictions that utilize the mitigation hierarchy. While there is recognition in the literature that wetland avoidance is not practicable in all circumstances, there is overwhelming consensus that in order to meet wetland management goals, more emphasis needs to be placed on avoidance. Government decision-making is highly influenced by the subjective and ill-defined notion of balancing development and the environment; hence, governments are often fraught with a permissive orientation that makes avoidance optional, or even an afterthought. Where wetland avoidance is ignored, impact minimization and compensation become the default regulatory processes for wetland conservation. We suggest that decision makers and regulators need to better consider the public goods and services that flow from wetlands, and account for these losses in all compensation schemes using the best social and ecological data available. A move towards a true cost accounting approach may help address the inequitable behavior of societies where a select number of individuals reap the short-term benefits of wetland loss, while the public pays the cost for generations to come.
The literature clearly suggests that avoidance is not synonymous with preventing wetland loss. A proactive approach to protecting wetlands requires land use planning that safeguards the ecological, social, and economic value and function of wetlands, both locally and within the larger landscape. We suggest that this can be better achieved by systemically planning for wetland conservation in advance of development, engaging the public in the monitoring and management of wetlands, and developing a more comprehensive valuation scheme that acknowledges the complex ecological and social values of wetlands at multiple spatial scales. For meaningful areas of natural wetlands to remain in jurisdictions that rely on the wetland mitigation sequence, the public’s ability to identify and communicate wetland values will need to develop commensurately with the unfolding development being leveled at wetlands, as this provides the greatest long-term hope for sustained public interest in policies that promote wetland conservation.
