Threatened & Endangered Species Assessment

Impacts to endangered and threatened species represent one of the highest-profile environmental issues of our time. Endangered and threatened species are found among all the various taxonomic groups from terrestrial and aquatic systems, such as mammals, birds, fish, aquatic invertebrates, insects, reptiles, amphibians, and plants. A wide range of human activities can potentially affect these species, including agriculture, dredging, timber management, industry, power generation, facility siting, linear/corridor projects, and water management. Numerous federal and state agencies are involved in enforcing endangered and threatened species regulations and evaluating potential harms to protected populations. In addition, many environmental organizations are very active in monitoring the possible effects of all of these diverse human activities and litigating against the EPA concerning potential effects on endangered and threatened species.
Exponent brings a well-trained, diverse group of regulatory and scientific consultants to bear on endangered and threatened species issues. Our team includes consultants with knowledge of the applicable laws and regulations, plus those with complementary scientific expertise, to address a client’s potential issues involving endangered or threatened species. This scientific expertise includes biology, population genetics, environmental DNA (eDNA), chemistry, toxicology, agronomy, and other fields that may be needed to address a specific endangered or threatened species issue. Exponent assists clients in determining the likely outcome of a regulatory agency evaluation of an endangered or threatened species issue, in responding to a regulatory agency determination concerning endangered or threatened species, and in developing and evaluating the most efficient and effective mitigation measures to address an endangered or threatened species concern.
