Celebrate Earth Week by digging in with Friends of Trees! Your help is needed to mulch hundreds of native trees and shrubs. We may also take out some weedy introduced plants, if time allows. Note: there will be no tree-planting at this event, and this is physically-demanding work (great for folks looking for a work out!). Our stewardship events help to ensure the highest level of plant survival through the PNW dry summer months ahead.
