Biological Services

SHN biologists increase project value by identifying potential impacts and providing recommendations for minimizing or avoiding them.

SHN’s wildlife biologists, botanists, wetland and stream ecologists, and soil scientists provide a wide range of services that address both public and private client needs in Northern California and Southern Oregon.  We are certified and licensed, energetic, and enthusiastic, with decades of local knowledge and experience. Our biologists maintain excellent working relationships with agency staff, which helps facilitate the permitting process, and we are known for thorough and accurate work which satisfies regulatory agency expectations and permitting requirements.

SHN biologists and botanists increase project value by identifying potential impacts and providing recommendations for minimizing or avoiding those impacts; the project may then require less regulation, an easier permitting path, and less cost.  For example, delineating a wetland and moving the project outside of its vicinity is a good example of mitigation by avoidance.  Fish relocation during temporary dewatering for bridge or road construction is another avoidance mitigation that SHN has successfully conducted. 

SHN’s biologists are practical and pragmatic, and our services are often provided to help clients stay in compliance with environmental regulations and requirements.  Our biologists and botanists design sampling efforts and collect data to fully address potential environmental issues but will refrain from collecting data without a specific goal or purpose. 

The following is a partial list of SHN’s biological services:

  • Biological Resources Assessments
  • Nesting bird surveys
  • Wetland and other waters delineation
  • Wetland design and restoration
  • Botanical (terrestrial, aquatic, and marine) surveys

  • Aquatic organisms passage (fish, amphibians) assessment
  • Mitigation programs (plans and monitoring)
  • Endangered Species Act Biological Assessments/Biological Evaluations
  • Ecological restoration and design

We specialize in civil, environmental, and geotechnical engineering; geosciences; planning and permitting; surveying and drones; environmental and biological sciences; and materials testing and special inspections.
