Wildlife Surveys & Monitoring

We work collaboratively with public agencies and private entities, guiding projects through permitting and regulatory requirements while helping balance development, restoration, and stewardship of California’s natural resources.

Wildlife & Ecological Research

We pride ourselves on bridging the gap between theoretical ecology and practical land management by providing actionable insights. Whether you have specific requirements necessitated by the National Environmental Policy Act or the Endangered Species Act, or need assistance developing a novel study to answer ecological questions, we provide an array of services including:

  • Environmental impact reports

  • Biological assessments

  • Biodiversity inventories

  • Nesting bird surveys

  • Mammal surveys

  • Herpetofauna surveys

  • Wetland delineations

Construction Monitoring

With more than ten years of monitoring experience, we support construction monitoring projects throughout Northern California involving a wide range of special-status species including:

  • Alameda whipsnake

  • California red-legged frog

  • California tiger salamander

  • Dusky-footed woodrat

  • Giant garter snake

  • San Francisco garter snake

  • Salt marsh harvest mouse

  • Western burrowing owl

  • Giant garter snake

Bat Surveys & Monitoring

Our biologists specialize in several bat survey techniques that are required for regulatory compliance. We can efficiently confirm bat presence or absence, track activity patterns, monitor roost health, identify species, determine relative abundance of bat populations, and mitigate impact to bat populations via:

  • Emergence and re-entry surveys

  • Maternity roost surveys

  • Mist net capture surveys

  • Disease testing and genetic sampling

  • Bat tracking, including PIT tagging and radio telemetry

  • Acoustic monitoring

  • Roost tree, mine, cave, and bridge surveys

  • Mitigation planning

Drone Services

With an FAA Part 107–certified remote pilot on staff, we provide drone-based aerial mapping to support ecological surveys, habitat assessments, and project planning. Drone imagery can be integrated with GIS analysis to efficiently characterize site conditions, document habitat features, and support spatial analysis at multiple scales.

All drone operations are conducted in accordance with applicable regulations and disturbance-avoidance protocols.
