Using the Revised Washington State Wetland Rating System (2014) in Western Washington

This two-day intensive workshop will provide wetland regulators and consultants with practical information and experience in using the revised rating system for wetlands in western Washington. It is specifically designed for those who will be using the rating system in the field. You will gain a working knowledge of topics such as the hydrogeomorphic classification of wetlands, how to separate wetlands into units for rating, and how to answer all the questions on the field form. The purpose of the class is to provide you with knowledge so that you can fill out the rating form on your own. You will receive a copy of the revised rating system.

It is important that you already have some experience and/or education in delineating wetlands and identifying natural wetland features such as outlets, boundaries of basins, vegetation classes, and some ability to distinguish between different plant species. The morning sessions will be held inside. The afternoon sessions will be conducted in local wetlands, so dress appropriately. (12 CM AICP Credits/CEP Points)
