Wetland Training Institute, Inc. provides professional training in wetland delineation, soils and hydrology, federal regulatory policy, wetland construction and restoration, plant identification, mitigation banking concepts, wetland policy and permitting, and other riparian resources conservation issues.
Who we are
Wetland Training Institute, Inc. meets the educational and technical resource needs of professionals involved in all aspects of water resource conservation, management, and regulation. We are an association of more than 20 individuals from private industry, academia, and government. It is this group of highly qualified and widely respected professionals that is the backbone of the courses and information available through WTI. WTI was formed in 1989 and is celebrating its 30th anniversary this year (2019).
WTI selects its instructors not only for their academic training and abilities to teach, but because of their backgrounds in the subject matter and their continuing application in the real world of wetland and water regulation. Each has an outstanding academic background. WTI instructors have been actively involved in the development of the technical procedures, manuals, policies, regulations, and judicial decisions that are the backbone of wetland science and wetland regulatory programs and they continue applying that expertise in permit cases throughout the country.
