Assessing Faunal Recovery in a Headwater Stream

A catastrophic fish-kill in a small tributary stream of the Etowah River system (Dawson County, Georgia) has created the opportunity to assess faunal recovery, including recolonization by a federally-listed fish species (the Cherokee darter Etheostoma scotti).  Fishes are expected to recolonize Flat Creek by moving upstream from downstream sources.  In particular, Flat Creek flows...

Response of fish assemblages and habitat to stream restoration in the Ashokan Watershed

Background: Streams are ecologically, culturally, and economically important systems that are subject to impacts from a large array of human activities. There has been a relatively recent increase in efforts to manage, protect, and restore streams that have experienced physical, chemical, and biological degradation. Unfortunately, interest in any single restoration effort tends to be...
