We specialize in providing highly qualified technical experts who will work with our clients to identify and assess key natural and cultural resource issues and develop project-specific approaches that minimize environmental impacts and facilitate regulatory approvals.

Our biologists understand the data collection needs and processes for complying with the biological resource provisions of CEQA/NEPA and other federal, state, and local statutes.
