Plant enthusiasts, hikers and others who want to help protect our natural areas are encouraged to join the effort to locate (and control) invasive species in the beautiful Middle Fork Snoqualmie Valley and the Snoqualmie Pass Gateway trails of the South Fork Snoqualmie. Help survey the area's spectacular trail system for invasive weeds so we can stop them before they get entrenched. This class will teach you to identify the highest priority invasive plant species and give you the tools you need to start helping prevent these weeds from spreading into our wilderness areas.

The training is a classroom-based workshop covering the program's goals and methods and focusing on learning to identify the priority invasive plants for the region, using a combination of slides and plant specimens. In addition, at the North Bend training there will be an outdoor activity to get further practice identifying plants and to get familiar with recording data on both the paper and online forms. For the Seattle training, we will schedule an optional weekend field day for plant ID and survey practice following the class. This is a joint training for King County's Trail Weed Watchers and the PNW‐IPC Citizen Science EDRR program.
