Project Solutions

If insects or other invertebrates affect your governmental or commercial projects, Entomological Consulting Services, Ltd. can help.

Our environmental services provide accurate scientific and technical data designed to help clients make better land use and resource management decisions. Our projects have included applied scientific studies and resource inventories, environmental impact analyses, preparation of resource management plans, and development of mitigation monitoring programs.

We can provide comprehensive survey and reporting of pertinent entomological issues at the early stages of a proposed project, or when questions or concerns arise at a later stage. Our goal is to give you the information needed to make sound project, resource, and land use decisions.
