Incorporating science into resource conservation and management is becoming increasingly important, but it is not yet clear how to provide information to decision makers most effectively. To evaluate sources of information used to support the management and conservation of California’s riparian bird habitat, we distributed a questionnaire to restoration practitioners and public and private land managers. We asked respondents to rate the importance and availability of different sources of information they use to inform their decisions. Synthetic reviews and peer-reviewed publications both received high importance and availability ratings. Web-based tools received low importance and availability ratings. One-on-one interactions between ecologists and decision makers received high importance ratings, similar to those of peer-reviewed publications and synthetic reviews, but their availability was rated lower than any other method of decision support. Our results suggest that the decision makers we surveyed are already using a wide variety of information, but that prioritizing one-on-one interactions between scientists and decision makers will enhance the delivery of all sources of information.

Over the last 50 years, ecologists have generated an immense amount of knowledge about how natural systems work and how to protect and restore them. Just as modern science has revolutionized medicine, there is now an effort to shift the management of natural resources from an experience-based approach to an evidence-based approach (Pullin and Knight 2001; Salafsky et al. 2002). A major challenge in developing evidence-based management is identifying the most effective ways to incorporate scientific knowledge into the decision-making process (Pullin and Knight 2005; Pyke et al. 2007).
There are many sources of information that can help land managers and policy makers incorporate scientific evidence into the decision making process (Alexander et al. 2009). These sources include a wide variety of printed documents and computer-based sources of information that help decision makers understand how different choices will influence the natural resources they manage. In the peer-reviewed literature, papers that emphasize the management implications of ecological research can be used for decision support. Outside of the peer-reviewed literature, documents that synthesize large amounts of ecological information into a single resource are becoming more abundant. Examples of such documents include the habitat conservation plans developed by Partners in Flight (Bonney et al. 1999; Alexander et al. 2007), the systematic reviews prepared by the Center for Evidence-Based Conservation (Pullin and Stewart 2006), and “white papers” prepared to address specific management issues. There have also been efforts to provide decision support information in an interactive format, often available online, that allows managers to design and evaluate multiple alternative management scenarios or view spatially-explicit databases of previous management efforts or conservation priorities (Rauscher 1999; Twedt et al. 2006; Katz et al. 2007).
The conservation and restoration of riparian ecosystems illustrates many of the challenges of integrating ecological science with on-the-ground decisions. In North America alone, more than 1 billion dollars are now spent on riparian restoration each year (Bernhardt et al. 2005), but the degree to which these projects are informed by ecological science remains highly variable (O’Donnell and Galat 2008). Over the last two decades, PRBO Conservation Science (hereafter PRBO) has been involved with research designed to inform the conservation and restoration of riparian bird habitat in California. To communicate research results to land managers and policy makers, PRBO has worked to provide reports and peer-reviewed publications to land managers and participated in the development of synthetic reviews, such as the California Partners in Flight Riparian Habitat Conservation Plan (RHJV 2004).
In order to evaluate the importance and availability of information that PRBO provides for the management of California’s riparian bird habitat, we distributed a questionnaire to restoration practitioners and public and private land managers. Here we report on the perceived importance and availability of five sources of information for decision makers. Our results have broader implications for improving the delivery of information designed to support decisions related to habitat conservation and restoration. This example may encourage other researchers interested in decision support to conduct similar efforts to understand the needs of their audiences.
With input from PRBO staff involved with riparian ecosystem research, outreach, and education, we designed a questionnaire to generate information about the importance and availability of sources of information used to support decisions associated with riparian habitat conservation and restoration in California. The questionnaire began with two questions that described the professional affiliation and responsibilities of the respondents. This was followed by a series of 24 topics, grouped into six categories, for which we asked respondents to rate the importance and availability. A copy of the questionnaire is available upon request from the authors.
Both importance and availability ratings were based on a three-tiered categorical scale. For importance, the categories were low—“information rarely or never considered in your riparian projects”, moderate—“information useful in only half of the riparian projects with which you are involved”, or high—“information critical to every riparian project with which you are involved”. Similarly, for availability the categories were low—“information is not available”, moderate—“some information is already available, but more is needed”, and high—“sufficient information is already available.” We asked respondents to rate availability independent of the importance rating, such that even if a topic was of little importance to most projects, the availability would still be rated high if considerable information was available for this topic.
We distributed our survey in two ways. First, we solicited responses to a paper copy of the survey that was distributed during the poster session of the 2007 State of the Estuary meeting in Oakland, California and the 2008 Riparian Habitat Joint Venture meeting in Sacramento, California. We also designed an identical online version of the survey and sent out a request for responses to e-mail lists maintained by California Partners in Flight, the Western Chapter of The Wildlife Society, the San Francisco Bay Joint Venture, and the PRBO Conservation Science Restoration Group.
Five formats of information transfer and decision support for which respondents were asked to rate the importance and availability
Method described in questionnaire
Peer-reviewed scientific publications in bird and ecology journals (Condor, Conservation Biology, Restoration Ecology, etc.)
Unpublished reports to management agencies
Printed (also available on-line) sources that synthesize the result of multiple studies (e.g., Cal PIF Riparian Habitat Conservation Plan, handouts, brochures, conservation plans)
Interactive web-based decision-support tools and information
Field trips, workshops, or one-on-one visits in which the developers of decision-support information explain, discuss, and guide their implementation
We received a total of 86 completed surveys, 19 paper copies from the meetings and 67 electronically. In the surveys we received, respondents identified their professional associations with environmental consulting firms (26 respondents), federal land or wildlife management (18 respondents), non-profit conservation or restoration organizations (16 respondents), state land or wildlife management (14 respondents), city or county land management (4 respondents), and other (8 respondents). Respondents that gave their professional affiliation as other included researchers, agriculture trade group representatives, Joint Venture coordinator, and utility and water agency representatives. Because the sample for city and county land managers was <5, we included them with the “other” category for all further analyses. The majority of respondents identified the decisions they make as involved with managing riparian habitat and designing riparian restoration. A lesser number made decisions related to awarding funds to riparian projects or selecting sites for restoration.
As with all surveys that rely on non-random samples, the potential for self-selection bias is important to consider (Berk 1983). If the views of individuals that chose to respond to the survey were not representative of the entire sampling frame, then it would be inappropriate to generalize to the larger population. Thus, our results should be interpreted with caution. With this caveat in mind, we believe our results suggest three major points that ecologists should consider as they develop information to support decisions by land managers and policy makers.
Peer-reviewed publications and synthetic reviews are important and available
Often, one hears the statement that “managers don’t have time to read the peer-reviewed literature.” In contrast, our results suggest that peer-reviewed publications and synthetic reviews are perceived as an important component of riparian conservation and restoration decision making. On the surface, this result appears to contradict what previous studies have suggested—that these sources of information are used much less frequently by resource managers and restoration practitioners than are many less formal sources of information, such as personal experience (Pullin and Knight 2005; Kondolf et al. 2007). In part, this discrepancy may be explained by the fact that our questionnaire only asked about formal sources of information and did not evaluate their importance relative to other sources of information. Among sources of information we asked about, peer-reviewed publications and synthetic reviews were perceived as the most important and available (Fig. 1).
We suggest that ecologists should not underestimate the importance of publishing their results and contributing to conservation plans, white papers, and other printed materials that can guide habitat conservation and conservation. However, as the volume of this information grows, so does the need for well-organized clearinghouses that make this information available to a wide audience (Kondolf et al. 2007).
Web-based tools are not yet important or widely available
The relatively recent development of sophisticated, interactive web-based applications has introduced an entirely new medium for providing information to managers and policy makers. However, despite the enormous potential of these tools, our survey results suggest that for riparian habitat conservation in California, they are not yet perceived as important or available. We do not suggest that web-based tools should not be developed. Indeed, we agree that making information available on the internet will have many positive outcomes for conservation and restoration ecology (Jenkinson et al. 2005). However, our results suggest that simply making these tools available on the web will not be effective. To increase the utility of these tools, ecologists will need to engage with decision makers to provide the training they need to effectively use the tools.
Ultimately, the utility of online applications may not be that they provide a single tool, but that they provide managers with access to a dynamic collection of tools. Such “decision support systems” could be designed to provide managers with access to a library of electronic versions of traditional printed documents and site-specific data dynamically displayed with custom visualizations. In North America, the Avian Knowledge Network (http://www.avianknowledge.net) fosters the development of such systems through its distributed nodes, such as PRBO’s California Avian Data Center (http://www.prbo.org/data) and Bird Study Canada’s Nature Counts (http://www.birdscanada.org/birdmon/default/) (G. Ballard, pers. comm.).
One-on-one interactions are important, but not available
Respondents from all professional affiliations agreed that one-on-one interactions with ecologists who develop information to support decisions are important, but not widely available (Fig. 1). This result supports the conclusion that collaboration between managers and scientists, not just more published studies, are needed to improve the practice of river restoration (Bernhardt et al. 2007). To provide effective decision support ecologists need to do more than simply provide a paragraph describing the “management implications” at the conclusion of peer-reviewed manuscripts; they must also find opportunities to interact with decision makers (Carr and Hazell 2006). The benefit of this personal approach is the opportunity for information to flow in both directions and for site-specific recommendations to be made which allows for a more collaborative interaction and process (Carr and Hazell 2006; Rumps et al. 2007). We suggest that the development of any decision support tool should not be considered complete until there have been formal steps taken to provide the one-on-one interactions that will train the audience in the use of the tool.
The important and urgent conservation and management decisions we face today require interdisciplinary approaches to provide decision makers with the best available information (Pyke et al. 2007). Our results indicate that ecologists and conservation biologists should develop a wide variety of decision support tools and prioritize the one-on-one interactions between ecologists and decision makers that will enhance their delivery. Although there is a clear need for one-on-one interactions, this is also one of the costliest modes of information transfer. Government agencies and philanthropic foundations that provide financial support for developing information to support decisions should also support activities that will provide the one-on-one interactions to ensure that information is used effectively.
