Background

Picture from the Long Creek Watershed The primary goals of the Long Creek case study include: 1) to serve as an example United States Environmental Protection Agency Stressor Identification (SI) case study, whereby the report may help future assessors understand the SI process for other biologically impaired ecosystems, and may help the broader scientific community better understand urban-related stressor interactions, and 2) to provide useful information for the improvement of the Long Creek watershed; this is especially timely, as stakeholders are currently considering options for promoting ecological recovery of the watershed.
