Abstract

As New Jersey population increases, urban landscapes and watersheds experience an increase in degradative anthropogenic affects. The issue to be addressed concerns ecological integrity in urban forested wetlands, almost completely overlooked. As benthic macroinvertebrate abundance and diversity directly affect the presence of larger organisms, ecological integrity is affected. The hypothesis to be explored opines that heterogeneity within wetland water channels, and substrate morphology combined with organic input from riparian vegetation can provide near optimum habitat for benthic macroinvertebrates despite degraded water quality and anthropogenic channel modifications.

Baseline data about physical and water quality parameters will be gathered; seasonal dynamics of the benthic macroinvertebrate community in wetland channels will be analyzed. Macroinvertebrate abundance and diversity will be correlated with channel morphology, substrate heterogeneity and water quality.
