Evaluation of Potential Impacts to Endangered Species that Use Wetland Areas: A Case Studyby Andrea Rosenthal,
Abstract: A proposed runway extension in an airport adjacent to a large riverine system and containing a small perennial branch of the riverine system would result in loss and modification of forested riverine habitat and upland deciduous forest. Concerns about the potential impact, loss, or modification of this habitat on the Indiana bat (Myotis sodalis) a federal and state listed endangered species, were raised by the United States Fish and Wildlife Service (USFWS). An evaluation of the project area was conducted during the time the bats were expected to be in residence. This evaluation was conducted to determine the suitability of the habitat to support summer roosting and to identify the presence of the Indiana bat in the area. The evaluation consisted of a field survey, a data search and interviews with resource agency personnel. The results of the field survey, data search and interviews were evaluated to determine the likelihood that the Indiana bat is present in the project area. Based on these results, recommendations for further studies and measures which should be followed during project construction to avoid impacting the Indiana bat were made.
