Threatened, Endangered, & Special-Status Species - Surveys & Permitting

Threatened Species Threatened Species

ECORP biologists provide habitat assessments and conduct determinate surveys for special-status plant and wildlife species including those protected under the federal and state Endangered Species Acts. Our staff has statewide experience working within a variety of habitats and natural communities. Our biologists are familiar with species' habitat components, life histories, and agency-approved survey methodologies. ECORP staff assess project-related impacts and consult with regulatory agencies to avoid, minimize, and/or mitigate habitat impact.
