Indiana Bat Survey

In 2010, GAI Environmental Consultants, Inc. contracted Davey Resource Group to complete an Indiana bat presence/absence mist-net survey along a 110-mile proposed natural gas pipeline corridor spanning two states and seven counties. Dominion Transmission, Inc. plans to install natural gas pipeline along this corridor within a 200-foot right of way.

Davey Resource Group has completed an initial reconnaissance study to determine proper site locations for mist-net placement. The study also gathered data to prepare a study plan for the client to use during coordination with federal and state agencies. Davey carefully planned the study and ensured its procedures followed guidelines recommended by the Indiana Bat Recovery Team and endorsed by United States Fish and Wildlife. This step was especially important to protect against the spread of white nose syndrome.

Mist-net sites were chosen in areas deemed as appropriate habitats for the Indiana bat; a total of 160 net sites were surveyed. Multiple survey crews worked simultaneously to complete this project within the specified timeframe. The fieldwork occurred within more than a two and a half month period to complete the mist-net surveys. During the mist-net survey, Davey provided progress updates to the client on a regular basis so that any obstacles or findings were clearly communicated. All mist-net locations were mapped using GPS and depicted on aerial photographs.

During the study, Davey participants captured a total of 1,322 bats of seven different species; however, they did not capture any Indiana bats. Upon completion of the fieldwork, Davey prepared detailed reports per the requirements of state and federal regulatory agencies.
