  • Uses specialized techniques and methods to collect biological and physical environment data from field and/or facility investigations and reports findings to determine actual and potential impact on fish, wildlife, or plant resources from aquaculture, research, restoration projects or habitat improvement projects.
  • Collects biological samples ensuring correct documentation, reporting, storage, transport and delivery of samples taken.
  • Assists biologists in studying and preparing reports on effects to ecosystems from development proposals of local, state, and Federal government organizations.
