The Rangewide Northern Long-eared Bat (NLEB) and Tricolored Bat (TCB) Determination key (DKey) is one of the final consultation streamlining tools available for NLEB and is only applicable to TCB if the final determination is to list the species under the Endangered Species Act. The goal of this DKey is to streamline review of routine, predictable projects that are not likely to adversely affect the NLEB and/or the TCB. This DKey is not appropriate for project types that include wind turbine operation or sustainable forestry, or projects included under other programmatic consultations. The DKey is available through the Service’s Information for Planning and Consultation website for projects with NLEB and/or TCB on their official species list. The DKey allows project proponents to receive automatic verification or concurrence for some actions and create official records for those outcomes for Endangered Species Act section 7 consultation.
