Observation Narrative	This site has a "quaking" mat of Polygonum fibers. The area is a large, open site measuring > 50 x 300 m. There are a few scattered, small Acer rubrum individuals not in the plot. Only a few shrubs are present either. For the area it appears that woody plants account for much less than 1% of the total cover.
