MACROINVERTEBRATE AND FISH COMMUNITY RESPONSE TO WETLAND RESTORATION IN WESTERN KENTUCKY
Wetlands improve the quality of our nation’s freshwater resources, and they support a diverse assemblage of plant and animal species. Each year, billions of dollars are spent on a variety of projects focused on restoring wetlands, including the Wetland Reserve Program (WRP). Our main objective for this study was to quantify macroinvertebrate and fish diversity on easements enrolled in WRP and in surrounding wetlands. Our study sites include restoration easements of various ages (0-15 years), agricultural fields prone to flooding as control sites, and mature bottomland forests, which represent pre-disturbance “reference” wetlands. Structures, such as levee breaks, ditch plugs, or shallow water areas have either been installed or removed on each easement to improve wetland hydrologic conditions. Stovepipe cores and multi-habitat dip-nets were used to collect macroinvertebrates at each site, while backpack electrofishing and throw-nets were used to collect fish. Preliminary results reveal that easements with a continuous hydroperiod and increased structural heterogeneity mimic reference wetlands in terms of both species richness and diversity. Understanding how these easements respond to restoration will provide opportunities for adaptive management in subsequent years.
