This one-day class will provide wetland regulators and consultants with a practical tool for calculating if mitigation projects will adequately replace the functions and values lost to altered wetlands. The class is based on a new method developed by the Department of Ecology called ""Calculating Credits and Debits for Compensatory Mitigation in Wetlands of Western Washington"" (Ecology Publication #10-06-11). This method is designed to provide guidance for both regulators and applicants during two stages of the mitigation process: 1) estimating the functions and values lost when a wetland is altered, and 2) estimating the gain in functions and values that result from the mitigation.



The Credit Debit Method is based on the Washington State Wetland Rating System for Western Washington (Ecology publication #04-06-025). This workshop however does not provide training in the wetland rating system. Training in the wetland rating system is strongly suggested as a PRE-REQUISITE for this workshop.



You will receive a copy of the “Credit-Debit” manual. The morning session will be held inside. The afternoon session will be conducted in local wetlands, so dress appropriately. (6 CM AICP Credits/CEP Points)


Lunch is provided.


Note:  This class will qualify you to use the 2014 Wetland Rating System if you have already taken the 2-day training in the older rating system in Western WA.


InstructorsDr. Tom Hruby was the former senior ecologist for the Shorelands and Environmental Assistance Program at the Washington State Department of Ecology, specializing in aquatic and coastal ecosystems. He studied the impacts of sewage and toxic chemicals on coastal, freshwater, and wetland ecosystems and developed models to assess the functions and values of wetlands. Tom Hruby developed 17 different methods for analyzing the functions that wetlands perform. He published over 25 papers published in peer reviewed scientific journals on environmental research and assessment methods.

Dr. Amy Yahnke
is the senior wetland ecologist for the Shorelands and Environmental Assistance Program at the Washington State Department of Ecology. She holds a Certificate in Wetland Science and Management, BS in Environmental Horticulture, MS in Forest Resources, and PhD in Aquatic and Fishery Sciences. She has studied wetland ecology within the contexts of amphibians, invasive plants, and stormwater management. Dr. Yahnke has experience teaching a wide range of environmental topics to audiences of all ages.
