visited and confirmed. We note that of the remaining five vegetated polygons without vegetation plots, one was also walked through on the way to other vegetation plots. These five polygons were observed visually from neighboring polygons and Witmer et al. 2002 rat eradication vegetation data was used to further confirm classification. Where there was any uncertainty in classification due to lack of field data, polygons were only identified to the Virgin Islands Subformation (Gibney et al. 2000), including four non-visited polygons. Thus SFCN felt the combination of these factors is sufficient enough to meet the National Vegetation Inventory Program standard of 80% classification accuracy with 90% confidence. As mentioned above the SFCN check of the horizontal accuracy indicated that positions of well defined points on the imagery were within 2.2m of their true location. A separate positional accuracy of the vegetation map was not possible, due to the scarcity of well-defined map-able objects. However, the accuracy of the imagery suggests that the map should be well within the 12.2 meters required by the NPS Vegetation Mapping Inventory Program. Summary of final project specifications, products and files The Buck Island vegetation map was made in UTM, NAD 83, zone 20N coordinates with a minimum mapping unit of 400m 2 . Aerial imagery used was a single U.S. Army Corps of Engineers natural color GeoTIFF orthophoto acquired as part of a larger collection in 2006-2007. SFCN tests showed the horizontal accuracy (RMSE) of the aerial image to be 2.2m. The final vegetation map has a total of 26 mapping classes and 51 polygons. A vegetation key and classification are included in Appendix A and a photo-interpretation key and map photos are included in Appendix B. Four proposed new Alliances, and 11 new Associations are described in the vegetation classification. A list of vegetation species observed in the field during this project is provided in Appendix C and a vegetation species photo guide for Buck Island Reef National Monument is provided in Appendix D. Data and photos were collected for 67 field plots as well as additional photos along trails or between plots. Ninety-two percent of the polygons either had vegetation data collection or were directly visited and confirmed; consequently SFCN feels the map meets the NPS VMP requirement of 80% accuracy with 90% confidence. The final product meets the FGDC metadata standard. Table 7 (page 23) summarizes the products and filenames included in the Buck Island Reef National Monument vegetation mapping project products and files. 14
