Threatened and Endangered Species

We perform full-spectrum habitat assessments and species-specific surveys for United States federally and state threatened and endangered species, as designated by US Fish and Wildlife and US state authorities. Internationally, we have performed surveys for IUCN Red List threatened species, including applying IUCN criteria to assess taxa for threat status at a global level.

We are well-versed in permitting, for both IUCN and US endangered or threatened species. For endangered species, permits may be issued for incidental take to an otherwise lawful activity, enhancement of survival,  and recovery and interstate commerce permits.
