BATS! – What’s the “Bat Window” and How Can It Affect Your Project?
Before the start of any construction project there are many details that should be addressed and planned for. Along with costs, professionally prepared plans and permits, nature-related restrictions need to be part of the discussion. One such restriction involves tree clearing as it relates to the natural habitat of bats. In the state of Ohio, if you are planning tree clearing, the USFWS recommends that it occur between October 1st and March 31st to accommodate the “bat window”. This is further supported by the Ohio Department of Natural Resources (ODNR) which protects and regulates the harm of species that occur in low numbers within the state. The reason for the date range is because bats typically hibernate over the winter in caves and abandoned mines and are less likely to be affected by tree clearing. Summer roosting habitats take effect in the late spring and summer months when bats roost in live or dead tree cavities, crevices and under loose bark putting them at risk if trees are being cleared. The trees with the highest bat “residency” tend to be oaks and maples but some species roost in hickory, elm, ash and occasionally pine trees. For any federally funded project or project that requires federal permits where tree clearing is proposed between April 1st and September 30th in Ohio, an ODNR approved bat survey should be performed to determine presence or probable absence of bats. Mist net surveys are conducted between June 1st and August 15th. Failure to conduct a survey will require strict adherence to the tree clearing date restriction. If a survey is conducted and probable absence of federally and state-listed endangered bats is recorded the findings are valid for a period of five years and tree clearing will be permitted outside the standard time frame. As you can see, failure to properly plan for the bat window can significantly delay the start or progression of your project costing both time and money.
