Natural Resource Inventories and Assessment


Natural resource inventories are essential for creating an accurate picture of the environment and are a necessary step in the evaluation ecological health. As a team of skilled environmental scientists, consultants and technicians, we emphasize the collection and production of scientifically defensible, ecological datasets that will be used to help our clients solve complex environmental challenges. With over 25 years of local, regional, and national experience EcoAnalysts is a recognized leader in the field.


Inventories compile and describe naturally occurring resources for: 

  • Land Use Management Plans 

  • Critical Habitat Evaluations 

  • Restoration Plans 

  • Conservation Planning and Design 

  • Environmental Compliance and Permitting 

  • Watershed Management Plans 

  • Wetland Delineation, Compliance, and Permitting 

  • Water Quality Monitoring Programs 

  • Impact Assessments 

  • Construction and Dredging Permits 

Freshwater and Marine Aquatic Inventories 

EcoAnalysts team brings a high degree and depth of experience to the evaluation of the ecological health of a given environment. Our services support reliable evaluation of the health and condition streams, rivers, lakes, and ocean, and environments. 

We have experience in designing surveys in small and large systems for various clients' in-stream construction and dredging permit needs. EcoAnalysts also provides services for federal and state agencies. Aquatic inventory services include species identification (including federal and state threatened and endangered species), faunal distribution mapping, formal technical report preparation, and economically feasible mitigation to meet  regulatory requirements

Available equipment includes boat mounted, tote barge, and backpack electrofishing units, as well as nets (hoop nets, gill nets, and seines). Equipment for various types of macroinvertebrate surveys is also available, including kick nets, Ponar dredges, and Surber samplers. 

Freshwater Mussel Surveys and Diving Operations 

EcoAnalysts biologists are certified through experience and species identification examinations by several state agencies to conduct freshwater mussel surveys, including threatened and endangered species.

Most freshwater mussel surveys in medium and large rivers require diving. EcoAnalysts' highly trained dive staff is committed to integrity, safety, and teamwork: characteristics evident in every EcoAnalysts dive operation. Safety is the primary concern of any reputable dive team. EcoAnalysts is a member company of the Association of Diving Contractors International (ADCI). We also meet or exceed the US Army Corps of Engineers and OSHA regulations for commercial diving. All field team members are Emergency First Responders (First Aid/CPR) as well as Oxygen Administration. 

Although our surface supplied air system is EcoAnalysts' preferred method of diving, some situations call for more portable solutions. EcoAnalysts has all the SCUBA and communications equipment necessary to safely meet diving objectives when surface supplied air is not an option. Divers and biologists are certified Rescue Divers through PADI (Professional Association of Diving Instructors). Additionally, we are currently developing a Scientific River Dive Safety course for USFWS that will be a PADI certification.
