State-listed Species Surveys

Huse Biological Consulting provides comprehensive surveys and habitat evaluations for state-listed species to determine their presence, distribution, and potential impacts within project areas. Using agency-approved protocols, biologists collect reliable field data that meet the requirements of California Department of Fish and Wildlife (CDFW) and other state wildlife agencies. This early identification of sensitive species allows projects to be designed or adjusted to avoid conflicts with state regulations and reduce the need for costly redesigns or delays.

We prepare detailed documentation to support state permitting and compliance processes, including California Endangered Species Act (CESA) Incidental Take Permit applications, species impact assessments, and resource management plans. Huse Biological Consulting works directly with state regulatory agencies to streamline reviews and ensure that all documentation meets current regulatory standards. Our team interprets complex state requirements and translates them into practical compliance strategies tailored to each project’s scope and timeline.


Huse Biological Consulting also provides on-site construction monitoring and environmental compliance oversight to protect state-listed species during ground-disturbing activities. Monitoring programs include implementing avoidance and minimization measures such as exclusion fencing, preconstruction clearance surveys, biological awareness training, and species relocation when authorized. By maintaining a consistent field presence, we help ensure adherence to permit conditions and provide immediate solutions to issues as they arise.


In addition, Huse Biological Consulting develops mitigation and habitat management plans to offset unavoidable impacts to state-listed species. These plans may involve habitat restoration, the establishment of conservation easements, or long-term biological monitoring to verify the effectiveness of mitigation measures. By combining technical expertise with regulatory coordination, Huse Biological Consulting helps clients achieve state compliance while supporting the recovery and long-term conservation of sensitive wildlife and plant populations.
