THE IMPACT OF RESTORING AN URBAN FORESTED WATERSHED ON EPT BIOMASS
Macroinvertebrates serve important functions in freshwater ecosystems as a link in freshwater food webs and are a source of biomass for higher trophic levels. Even though understanding macroinvertebrate biomass is highly important in freshwater ecology, it is often not an analysis included in restoration monitoring. To address this research need, we quantified macroinvertebrate biomass before and after restoration in a forested urban watershed. Samples were collected from 2016-2020 at within the Reedy Creek Nature Preserve in Mecklenburg County, North Carolina. Ephemeroptera, Plecoptera, and Trichoptera taxa were collected using the NC Qual-4 method along 50m stream reaches pre-restoration and 100m stream reaches post-restoration. Two years post-restoration results indicate total EPT biomass increased from 60.13 mg/m2 pre-restoration to 326mg/m2 post-restoration in the 2 sites influenced by urban development, total EPT biomass increased from 788.62 mg/m2 pre-restoration to 1156.4 mg/m2 post-restoration in the 4 sites influenced by historically agricultural land, and there was no evident change in total EPT biomass pre-restoration (229.38 mg/m2) and post-restoration (219.53 mg/m2) for the forested control site. We hypothesize that EPT biomass has increased post-restoration due to either the removal of predator or introduced substrate into the habitat.
