Forest Park is located within what is known as the Western Hemlock zone. In its natural, undisturbed condition, this zone is populated by three primary tree species: Douglas-fir, western hemlock and western red cedar.

Forest Park remains in a semi-natural condition and has maintained all of the western hemlock zone's naturally evolved, characteristic plants. However, one change is significant today. Instead of being dominated by evergreen trees, the park is clothed with a preponderence of red alder and bigleaf maple trees. Primarily due to extensive logging, evergreen trees have declined appreciably while hardwood species have proliferated. For more information on the Forest Park landscape, click here.
