All points fall within the mapped polygons. All vegetation plot sampling followed the USGS/NPS Vegetation Mapping Program protocols. The protocol recommends that each vegetation association should have been sampled at least three times in order to capture the naturally occurring variation within the park. If each of the identified formation-level vegetation types represented only one association in Friendship Hill National Historic Site, the minimum number of plots needed would have been 25. This assumed that areas labeled with modified Anderson level II categories would not be sampled, and that for formations with less than three polygons, one plot would be placed in each polygon. However, it is more likely that some formations represent multiple associations, and that a few formations actually represent the same single association. Therefore, we concluded that approximately 30 plots would be sufficient to capture the range of vegetation types based on our initial reconnaissance of Friendship Hill National Historic Site and previous vegetation mapping efforts at this and other parks. Polygons labeled Conical-crowned temperate evergreen forest were not sampled because they represented extremely small remnants of conifer plantations, a vegetation type adequately sampled at other nearby parks. Many of the Medium-tall sod temperate or subpolar grassland polygons were also excluded from sampling because they represented frequently mowed grasslands in which the plants could not be identified. Plot sampling was conducted in June and July 2004. In total, 32 plots were sampled throughout Friendship Hill National Historic Site. All vegetation types were sampled over a range of environmental variables. The two additional plots were added to the original sampling strategy. These plots were placed in a Saturated temperate perennial forb vegetation polygon and a Medium-tall sod temperate or subpolar grassland polygon in order to sufficiently capture the variation in species composition and environmental setting.
