Endangered Species Surveys

Expertise Areas

Our scientists have surveyed for federally protected plants and animals across the nation, resulting in distribution records and life history information for many investigated species. Eco-Tech holds scientific collection permits for over 50 federally-listed species in more than 20 states, including bats and other small mammals, freshwater mussels, fish, and plants. Eco-Tech biologists have additionally performed numerous surveys involving dozens of state-listed species from California to New Jersey.

Every project with the potential to impact a listed species demands experienced biologists versed not only in scientific methodology, but also the regulatory implications of a positive determination of presence. The capture or identification of a federally-listed species may only be the beginning of detailed strategy, negotiation, and field investigation tasks with multiple governmental agencies.

Formal consultation under the Endangered Species Act (ESA) can be a daunting challenge to even the most seasoned field biologist. Our senior staff scientists, however, have experience in the cost-effective preparation of formal Biological and Ecological Assessments and supporting technical documents, including Habitat Conservation Plans, for several species across the U.S.
