Tiger Mountain in Issaquah is a popular destination for hikers, mountain bikers, hang gliders, paragliders and horseback riders. Its trails bring visitors through the remains of old growth forests left over from Tiger Mountain’s logging past. Tiger Mountain has 65 miles of trails and 29 miles of gravel roads and the constant usage of these trails and roads causes them to erode over time. In addition, hikers and their vehicles become the vectors for invasive plants to enter the ecosystem, decreasing the ecological health of Tiger Mountain. Volunteers at Tiger Mountain will work together to help repair overused trails by resurfacing, brushing, fixing drainage issues, and repairing boardwalks. In addition, volunteers remove invasive plants like Scotch Broom and Himalayan Blackberry to allow native trees and shrubs to thrive. Volunteers help keep the trails and trailheads in good shape so people can continue to come back each year to enjoy the mountain’s beauty.
