In April 2015, the U.S. Fish and Wildlife Service (“Service”) published a final decision to list the northern long-eared bat as threatened and, rather than publishing a final 4(d) rule, opted to publish an interim 4(d) rule and open a 90-day comment period to gather additional information and potentially refine the interim 4(d) rule.

As we discussed in a post last year, the effect of the interim 4(d) rule depended on the location of a particular activity. For areas of the country not affected by white-nose syndrome, the interim 4(d) rule exempted incidental take from all activities.  For areas of the country affected by white-nose syndrome, the interim 4(d) rule exempted from Endangered Species Act take prohibitions the following activities: (1) forest management practices, (2) maintenance and limited expansion of transportation and utility rights-of-way, (3) prairie habitat management, and (4 ) limited tree removal projects, provided these activities protected known maternity roosts and hibernacula.  Under the interim 4(d) rule, those activities were exempted provided: (1) the activity occurred more than 0.25 mile (0.4 km) from a known, occupied hibernacula, (2) the activity avoided cutting or destroying known, occupied roost trees during the pup season (June 1–July 31), and (3) the activity avoided clearcuts (and similar harvest methods, e.g., seed tree, shelterwood and coppice) within 0.25 mile (0.4 km) of known, occupied roost trees during the pup season (June 1–July 31).  Thus, with a few narrow exceptions, the interim 4(d) rule prohibited all incidental take within areas of the country affected by white-nose syndrome, including take resulting from the operation of utility-scale wind turbines.
