This dataset represents a species habitat distribution map for Hoary Marmot (Marmota caligata) within the conterminous United States (CONUS) based on 2001 ground conditions. This habitat map was created by applying a deductive habitat model to remotely-sensed data layers within the species' known range. See Gap Analysis Project Species Habitat Maps for more information regarding model process and user constraints. For species specific model information, see the attached Species Habitat Model Report.

Dam removal has been proposed as an effective method of river restoration, but few integrative studies have examined ecological responses to the removal of dams. In 1999, we initiated an interdisciplinary study to determine ecological responses to the removal of a 2 m high dam on lower Manatawny Creek in southeastern Pennsylvania. We used an integrative monitoring program to assess the physical, chemical, and biological responses to dam removal. Following removal in 2000, increased sediment transport has led to major changes in channel form in the former impoundment and downstream reaches. Water quality did not change markedly following removal, probably because of the impoundment's short hydraulic residence time...
