Along the southern shore of Hummingbird Lake is an area of intact old-growth Douglas-fir forest. It lies within Woodlot 2031, which is operated by Okisollo Resources. The area of old-growth is unprotected. In the photograph below, which looks towards the east end of Hummingbird Lake, the old-growth forest is visible on both side of the lake and high on a ridge southeast of the lake. The right side of the photograph shows the south side forest.
