Ecological Impact Assessments


Our philosophy balances development and the environment to foster economic growth while preserving the integrity of our shared natural resources. Our goal is to develop common sense approaches to environmental concerns. With our extensive knowledge and resources, we provide results that are reliable, consistent, and easily interpreted and approved by regulatory agencies.


EcoAnalysts has extensive experience with state and federal regulatory agency personnel and regulations, particularly with respect to threatened and endangered species. We excel at combining our expertise in ecology and life history with various construction, operation, and management methods to provide our clients with creative solutions that are readily accepted by regulatory agencies. 

EcoAnalysts surveys and reports always consider regulatory and legal implications, as well as client needs. We provide clients (both government and private industry) with defensible data and expert testimony when needed. 

Biological Assessments 

EcoAnalysts ecologists are highly experienced in preparing Biological Assessments in multiple states. Additionally, our biologists and taxonomists are recognized internationally as experts in their field and have been frequently called upon to give their expert testimony. 

Change in community structure and function can indicate there has been positive or negative impact to environmental conditions, whether by nature or by human action. 

The applications for this approach are wide and varied, including: 

  • site-specific or regional water quality monitoring  

  • baseline ecological assessments  

  • restoration effectiveness  

  • remedial investigations  

  • ecological risk assessment  

  • contaminated sediment site cleanup and monitoring  

  • end of pipe monitoring 

  • climate change monitoring  

  • natural resource damage assessments (NRDA) 

  • stressor identification 

  • food web modeling, and more.  

EcoAnalysts has been an internationally recognized expert in this specialized field of biological assessment for well over 20 years. 

Aquatic Systems 

Biological community indicators, such as fish, invertebrates, plankton and periphyton are widely used to evaluate change in aquatic environments. We house North America’s largest taxonomy services laboratory and our taxonomy lab is one of a very select few laboratories that offers taxonomy services for all groups, including freshwater and marine, under one roof. 

Our taxonomists are individually certified by the Society of Freshwater Science and we serve as technical experts to inform clients of biological condition, potential causes of impact and the ecological relevance to their projects. 

Terrestrial Systems 

EcoAnalysts is excited to offer expanded services in terrestrial systems biological assessments. We will bring the same level of expertise, professionalism and consideration to land-based projects as we have for decades with our proven record in aquatic systems.

Habitat Assessments and Species-Specific Surveys 

Habitat availability determines species composition and distribution and is the key stepping off point for any major project. A thorough and complete initial habitat assessment can identify potential diversity constraints and improve project designs and efficiency.  

Habitat can be incredibly hetergeneous, which is why EcoAnalyst biologists utilize multiple methods of data collection and analysis in their assessments, including: 

  • SCUBA surveys 

  • GIS/GPS spatially explicit mapping 

  • Qualitative Habitat Evaluation Index (QHEI) 

  • Aerial surveys with UAV’s 

  • Vegetation surveys (aquatic and terrestrial) 

EcoAnalysts biologists hold multiple collection permits or can quickly obtain permits needed to complete your assessment. We have experience completing habitat assessments and species-specific surveys for state and federally listed endangered and threatened species including freshwater mussel surveys and translocations and crayfish. 

EcoAnalysts has a strong reputation with regulators and agencies and can quickly mobilize to obtain Population Estimates, perform Qualitative and Quantitative Surveys and Presence Absence surveys to move your project forward.
