Vegetation Characteristics: Overall, the species in the overstory and understory over the majority of the site are (check box):

Native: > 75% Mixed: 51-75% native Mixed: 51-75% exotic Exotic: > 75%

For overstory and understory characteristics (below), dominant species are those representing a majority of the
sampled cover throughout the site. Codominant (2nd, 3rd, etc.) should also be ranked to reflect their relative
proportion over the entire site.  Substantive differences among patches within the site should be noted in comments,
below, or on the last page.

Is surface water present within 300 m of this site? YES_____ NO _____ Is that true for all patches? YES_____ NO _____
Describe in comments the nature (type, size) of water (when present) and note differences among patches within the site.

Remember to describe in comments any substantive variation between patches. For example, the average canopy cover for
the site is 30%, but within Patch 3 it is 60%. Similarly, if other vegetation parameters show considerable variation it
should be noted. Document these differences with photographs whenever possible.  Be sure to reference comments to
appropriate photo #s and note #s.  Photos should provide both overviews and details of the habitat and, of course, any
YBCU locations.
