The northern long-eared bat population has declined as a result of the white-nosed syndrome. Although forest harvesting does not impact the bat or habitat per se, felling a tree where a bat is located or disturbing a hibernaculum would be problematic. There are both state and federal regulations that apply.
Here is communication from NYSDEC on May 5 2016
"As you may know, the northern long eared bat (NLEB) has been listed by the USFWS as threatened due to declines as a result of white nose syndrome. The FWS has also issued a 4(d) regulation that enables certain forestry practices to continue.
NYS Part 182 regulations for the protection of endangered species also apply. DEC restrictions are less flexible than a threatened status under the federal law so we have some additional restrictions beyond the 4(d) rule.
Attached is guidance on how DEC will be protecting NLEB under Part 182, as well as maps indicating known roost trees and hibernaculum. Please note that these restrictions related to cutting trees are not intended to protect NLEB habitat; loss of habitat is not an issue for NLEB survival and most normal forestry practices are not the issue. The restrictions are intended to protect any bats that may be in the trees and would potentially be harmed by the cutting of that tree. Hence, the focus on snag and cavity trees, which are the likely roosting locations, and lesser restrictions during the time of year the bats are in hibernation. "
Some of the cutting restrictions apply to snag and cavity trees. The definition of a snag / cavity tree are at http://www.dec.ny.gov/docs/lands_forests_pdf/policysfrention.pdf ;
Cavity Tree – Live or dead tree with excavations sufficient for wildlife nesting, denning and shelter.
Snag – A standing dead tree that is at least 20’ tall (DeGraff and Shigo, 1985).
