Original Paper
Turner et al. ( 2017) report on wetland degradation following introduction of secondarily-treated municipal effluent into a freshwater emergent and forested wetland in southeastern Louisiana, referred to as the Hammond assimilation wetland (HAW). They assign the cause of the wetland loss to a combination of increased decomposition and decreased soil strength due to the presence of nutrients from the effluent that led to buoyancy in the marsh soil. They do not, however, discuss or even cite two other papers that have examined the same wetland and have come to different conclusions (Shaffer et al. 2015; Lane et al. 2015), specifically that nutria herbivory was the main cause of the wetland deterioration (Fig.  1), or a workshop in October 2016 where these issues were discussed in detail. Most importantly, the authors fail to mention or consider that the wetland vegetation began to recover as soon as nutria control was implemented (Fig.  2), though with a different species assemblage most...
