II. ENVIRONMENTAL / SITE DESCRIPTION
1. Environmental Comments (if site is a wetland, indicate type of hydrology, e.g., seepage wetland, temporarily
flooded stream bottom, seasonally flooded pond, etc.)
III. VEGETATION DESCRIPTION (observation is within a 0.5 ha area – approx. a 40 m radius circle)
1. Prevalent vegetation association within 0.5 ha of observation area, based on field key:
2. Other vegetation associations present within 0.5 ha observation area:
3. Representativeness: is the vegetation within the 0.5 ha observation area representative of vegetation in the
surrounding mapped polygon? If vegetation of the AA point is an anomalous inclusion in the polygon, please note
4. Approximately what percentage of the mapped polygon did you observe? OR approximate size of area observed?
(This may be also be drawn on a map. Include
with form)
