Ecological Services

The National Environmental Policy Act (NEPA) is the United States' method of ensuring environmental impacts are considered during project planning and approval activities by federal agencies. Trihydro has experience preparing Categorical Exclusion Forms (Cat-Ex), Environmental Assessments (EAs), Programmatic Environmental Assessment (PEAs), Biological Evaluations (BEs), Biological Assessments (BAs), and developing Environmental Impact Statements (EISs) for project areas ranging from a few acres to tens of thousands of acres. Trihydro’s NEPA team is comprised of experts in a variety of scientific fields, enabling us to prepare accurate and scientifically supported NEPA documents. Trihydro’s NEPA team has considerable experience in considering various project alternatives and providing recommendations to avoid, minimize, and/or mitigate environmental impacts so final outcomes achieve client objectives while satisfying regulatory requirements.

• Threatened and endangered (T&E) species surveys
• Wildlife assessment/surveys
• Avian assessment/surveys
• Vegetation assessment/surveys

Biological surveys may be completed on-the-ground or via remote sensing.

Trihydro’s biologists have conducted biological surveys and habitat assessments across the country for a variety of complex projects. We have led field studies for dozens of projects involving small mammal trapping studies (including mark-recapture), raptor nest inventories, migratory bird point-count surveys and nest surveys, T&E species protocol surveys, acoustic bat surveys, broadcast acoustic surveys, herptile surveys, plant community surveys, and invasive plant assessments. In addition to field collections, our staff is well versed in analyzing, synthesizing, and interpreting complex surveys in the form of reports and summaries.

Our biologists have extensive experience in identifying, characterizing, and mapping habitats for a variety of wildlife including various T&E wildlife species. Trihydro biologists specialize in permitting for activities with potential impacts on species of concern, and are experienced in Section 7 consultation with the United States Fish and Wildlife Service (USFWS), state wildlife regulations, and conservation programs.

Our interdisciplinary staff of biologists, ecologists, environmental scientists, GIS-analysts, engineers, and geologists combine GIS mapping techniques and aerial data collection, such as unmanned aerial systems (UAS) and manned flights, with extensive knowledge of wildlife habitat utilization to perform accurate and representative habitat evaluations for many species of plants and animals. Trihydro’s GIS analysts work seamlessly with field biologists to prepare for field data collection and inventories, generating high-quality maps that show distributions of individuals and populations.

Trihydro supports clients in several key areas of ecosystem management, including habitat restoration and reclamation, invasive plant management planning, revegetation, and soil fertility management. We are well-versed in the flora and fauna of the diverse ecosystem types found across the United States. Our ecosystem management approach is focused on proactive communication with agencies and our clients to enable efficient project planning, reporting, and permitting.

Our team has expertise in collaborative conservation and multi-stakeholder restoration planning. Our ecologists plan and facilitate meetings and stakeholder outreach, help with negotiations, and guide decision-making throughout the ecosystem management planning process. We have successfully used adaptive management on our projects and have developed strategies for sustaining momentum so ecological planning goals are realized on-the-ground.
