This three-day intensive workshop will provide wetland regulators and consultants with practical information and experience in using the revised rating system for wetlands in eastern 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.

This course will include two required virtual sessions on Zoom on 10/15 (9:00 am - 12:30 pm) and 10/16 (9:00 am - 12:00 pm). Participants will visit sites with the instructor in Spokane on 10/17 (9 am - 4:30 pm). The field session will be conducted in local wetlands, so dress appropriately. Note: All cars driving to the field sites will need a Discover Pass.

It is mandatory to attend the virtual sessions on 10/15 and 10/16 and in-person field session on 10/17 in order to obtain your certification for the rating system (13 CM AICP Credits/CEP Points).
