BFSA's consulting biologists are involved in a wide variety of biological work associated with the study of regional ecosystems. Our projects focus upon the characterization of biological resources, the assessment of potential projects to support threatened and endangered species, and presence/absence surveys for sensitive resources. BFSA's consulting biologists are familiar with critical habitats, including coastal sage scrub, chaparral, and mountain and desert habitats in the western and southwestern United States.

BFSA’s diverse staff of plant ecologists, wildlife specialists, and aquatic and wetlands professionals have experience with studies ranging from database and extensive field surveys to development of comprehensive mitigation programs. Our extensive experience includes conducting major field surveys requiring large teams of personnel to survey remote areas such as deserts or forests, preparing natural resources and habitat management plans, conducting wetlands delineations and marsh restorations, and enhancement for coastal and inland wetlands.
