Old Growth Trail passes through an old growth reserve. Old growth reserves located within McDonald Forest are low-elevation coniferous forests containing some large, 200+ year old Douglas-fir trees, as well as snags and fallen trees. Snags are standing dead trees. Students and researchers study the ecology of these old growth reserves. Old Growth Trail is just under a half of a mile in length with a 50 foot gain in elevation. Although the area surrounding Old Growth Trail was logged historically, the trees in the valley where the trail is located were not harvested due to the steepness of the valley. Although steep, the trail has been developed with rails, stairs, and bridges to make it more accessible. This trail provides visitors with the opportunity to marvel at some of the biggest trees within McDonald Forest. Interpretation is located along this trail and provides further information regarding old growth forests. Other fauna of interest along this trail include tall bugbane, an uncommon native wildflower. Tall bugbane flowers in the early summer and can reach heights of three to seven feet. The old growth characteristics observed along the trail are typical of the locations spotted owls inhabit. Currently, the spotted owl is listed on the threatened species list. A hike along this trail offers visitors the rare opportunity to explore an old growth forest community. Make time to hike this trail and immerse yourself in the wonder and awe created by big trees!
