Acer macrophyllum or big leaf maple sometimes forms the predominant stand in the forest. These stands can be long lasting in part because the maple trees do not die when cut. Maples will send up an inverted chandelier of stems from the trunk and rapidly form a dense seasonal canopy that appears to effectively block out other competing trees. I am aware of a few stands that are 100 years old. This particular stand shown below grew up out of a clear cut harvest of a mixed stand of mature Douglas fir, western red cedar, grand fir and western hemlock on a moderately steep slope. The maples have since been cut but have grown right back up again.
The geology of the site is an advance glacial outwash sand, a compact sand slope on a very old deep-seated landslide head scarp with an east facing slope aspect.
