Environmental Assessments

Endangered Species

Collecting data on endangered species and critical habitat concerns for our energy, infrastructure and industrial market clients.

Identifying and addressing rare, threatened and endangered species

The U. S. Fish and Wildlife Service (FWS) and National Marine Fisheries Service (NMFS) share responsibility for administering the Federal Endangered Species Act (ESA). In addition, many states have their own regulations that expand the potential list of flora and fauna involved in siting and permitting projects.

TRC’s team of GIS experts and biologists perform initial desktop data collection and assessment, and then study/survey plans are developed to meet agency requirements while minimizing the cost to our clients. Our large group capability allows us to put multiple field teams in action simultaneously, and to cover all states.


Our team efficiently and accurately collects data, whether it is for habitat surveys or presence/absence surveys and prepares this information for inclusion into Biological Evaluations (BE) and/or Biological Assessments (BA). We identify potential RTE species and/or critical habitat issues and addresses agency concerns in a responsible, efficient and cost-effective manner to meet project needs and comply with federal and state protocols.

Our RTE Species Assessment Services Include:

  • Applicant Representation During Permitting
  • Informal and Formal Consultations
  • RTE Species and Habitat Surveys
  • Critical Habitat Surveys
  • BE and/or BA Preparation
  • Habitat Conservation Plan (HCP) Development
