Wildlife species, while often elusive, can be key players in aquatic and terrestrial ecosystems as top predators within the food web, indicators of ecosystem health within the forest or riparian corridor, or sensitive species with unique habitat requirements. We routinely conduct:

  • Special-status species habitat distribution and use (complete list of species we have worked with and have obtained State and/or Federal authorizations)
  • Focal species analysis
  • Wildlife habitat management (e.g., effects of flow on amphibians or transmission lines on raptors)
  • Regulatory compliance – including BAs, HCPs, EIS/EAs, EIR/Negative Declarations, ESA consultation
  • Baseline monitoring for evaluating restoration designs and assessing project impacts
  • Pre-construction surveys to meet environmental compliance (details on our pre/post construction monitoring experience)
  • Post-restoration monitoring to evaluate use and habitat effectiveness
  • Analysis of effects of flow regulation on amphibian distribution
  • Benthic macroinvertebrate abundance and diversity to calculate indices of stream integrity
  • Northern spotted owl effects analysis
  • Structure evaluation for use by bats

Stillwater Sciences uses an ecosystem approach to wildlife management to evaluate the underlying causes and mechanisms for the distribution of wildlife within a project area, usually beginning with a thorough understanding of the species' habitat needs through various life stages. These habitat needs can be evaluated in light of other biological and management issues to find opportunities where multiple species and resources can benefit. We use new and creative ways to monitor and assess wildlife populations in the field, develop restoration programs and designs to help restore these populations, and develop mitigation measures for environmental compliance required under the federal and state Endangered Species Acts, NEPA, or CEQA.



Our wildlife crews study everything from foothill yellow-legged frogs to fishers.

Developing frog-friendly flows

We’ve applied innovative methods to evaluate amphibian habitats downstream of dams to help develop beneficial flow release schedules as part of a number of hydroelectric project relicensings.

Documenting falcon breeding success

Our peregrine falcon survey team overcame early morning starts, overgrown trails, and steep slopes to get the best vantage point to document nest occupancy and breeding success.

Bats guide river restoration

Solar-powered acoustic detectors were used in this pilot study to monitor bat activity in various habitats along the Sacramento River corridor to evaluate restoration effectiveness.
