Observation Narrative	Vegetation dominated by overstory Quercus montana and understory Tsuga canadensis once covered a large area on this slope. Most of the Tsuga has succumbed to an outbreak of hemlock woolly adelgid within the past 10-15 years. Plot is located in a small area where more or less continuous Tsuga cover still persists, although most trees are infested and have thin foliage. This was ignored when projecting vertical cover of Tsuga.
