Maintaining Diversity in Created Wetlands

FHWA FY07 STEP Project:
How wetland mitigations replace wildlife function and values has received little attention despite efforts by wetland regulators to require performance standards for wetland mitigation areas. The focus should be on wetland mitigation banks as they typically possess a greater area than project-by-project mitigations and therefore provide more habitat opportunity. Wetland mitigations are often planned to compensate for flood attenuation, filtration, and specific plant community composition but not usually designed for specific or a variety of wildlife species. The usage of wetland mitigations by wildlife should be documented by habitat type and species using that particular habitat. A comparison can be made to the impacted wetland to verify if the mitigation site is compensating for the same or different wildlife usage. The data collected could possibly be integrated into a predicative model for determining which animal species and how many different species use a particular habitat type. Standardized methods to collect such information would be beneficial in determining how specific mitigation design elements contribute to successful mitigation of wildlife function. The objective of this research will be to document specific wetland habitat and the variety and number of wildlife species utilizing that habitat. The research may be useful for designing wetland mitigations to achieve a specific or desired variety of wildlife species based on their habitat requirements and use.
