Biological Resources

RECON provides a full range of natural resource services for a wide range of projects. Our specialists include wildlife biologists, botanists, wetlands and permitting specialists, and preserve managers. We have extensive experience conducting threatened and endangered flora and fauna surveys in compliance with state and federal protocols such as the State and Federal Endangered Species Acts, Migratory Bird Treaty Act, and Clean Water Act. Through our positive relationships with staff at the U.S. Fish and Wildlife Service, U.S. Army Corps of Engineers, and California Department of Fish and Wildlife, combined with our solid understanding of applicable local, state, and federal regulations, we efficiently guide clients through the environmental process to secure regulatory permits.
