Upper Snoqualmie Weed Watchers - Citizen Science Early Detection Rapid Response Invasive Plants Training

Pacific Northwest Invasive Plant Council - Call for citizen scientists: Join a regional volunteer effort to detect and eradicate invasive plants!
COVID-19: Learn about our most up-to-date guidance for participants and leaders on our COVID-19 Response page. All participants and leaders must agree to the COVID-19 Code of Conduct before participating in this Mountaineers event.

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. The Upper Snoqualmie invasive weed project trains volunteers to survey along the beautiful trails of the Middle Fork Snoqualmie Valley and in the upper South Fork Snoqualmie watershed. Help survey the area's spectacular trail system for invasive weeds so we can stop them before they get entrenched. We are surveying trails from Mt. Si near North Bend to Dutch Miller Gap in the heart of the Alpine Lakes Wilderness.

Please join us at this training session to learn to identify priority invasive plants, record basic data, and report findings. We will give you the knowledge necessary to do invasive plant surveys that will support local land managers that need your help. 

The training is FREE. We just ask that volunteers conduct 1-2 surveys over the field season. Your efforts will directly support the maintenance of healthy ecosystems.


The Pacific Northwest Invasive Plant Council (PNW IPC) is a non-profit conservation organization working in partnership with U.S. Forest Service, National Parks, Washington Department of Agriculture, Washington Department of Natural Resources, county noxious weed programs and conservation districts, and other organizations on a Citizen Science EDRR (Early Detection Rapid Response) program to track priority and newly emerging invasive plants. Volunteers provide crucial assistance in preventing further spread of invasive species!
