Points of Interest

1. Towering Douglass Fir Trees

Look up into the canopy for a glimpse of individual Douglass fir tree crowns. There are many species who use individual trees (especially broken or snag trees) for nesting or hunting spots.

2. Older Forest

Here, the new 3rd or 4th generation forest (logged 10-20 years ago) butts up against older 2nd generation forest.

3. Maple Understory

In some places, the logging operations have opened up opportunities for maples and other hardwoods to take over.

4. Logging Operations

In parts of the trail system, selective logging is permitted. These areas are not clearcuts, but rather thinning of selected trees which allows the forest to recover quicker and for younger trees to reach maturity. It also prevents the runoff and erosion associated with clearcutting of steep hillsides.
