Base Map Class Development overlays, was then added to the attribute table of each base map polygon. Additional attributes, including vegetation associations and communities, were then incorporated using a tabular join in ArcGIS 9.2. The resulting vegetation map, in shapefile format, was then reviewed independently for attribute accuracy through a “heads-up” comparison of the vegetation map with the original orthorectified overlays in the ArcMap application of ArcGIS 9.2. 3.2 Results The vegetation map database for PEFO (fig. 9, table 7) encompasses 46 base map classes: ● 8 classes describing infrastructure ● 5 describing land cover and geology types ● 4 describing sparse vegetation ● 15 describing grasslands ● 15 describing shrublands ● 2 describing woodlands and forests. The vegetation map database is georeferenced to Universal Transverse Mercator (UTM) projection North American Datum of 1983 (NAD 83) zone 12. The vegetation map database contains 6,989 polygons, of which 1,956 (28%) are smaller than 0.5 ha (table 8). The majority of the vegetated polygons smaller than 0.5 ha in size occur in nine base map classes. Map classes that occurred in the barren badlands were relatively easy to distinquish from unvegetated areas on the aerial photography and were often mapped even when the patches were less than 0.5 ha in size. but were included within the surrounding mapped vegetatation: 1) Artemisia filifolia / Bouteloua eriopoda Shrubland, 2) Forestiera pubescens Temporarily Flooded Shrubland Alliance, 3) Krascheninnikovia lanata Dwarf-shrubland, 4) Suaeda moquinii Shrubland, 5) Sporobolus coromandelianus Herbaceous Vegetation, and 6) Sporobolus cryptandrus Great Basin Herbaceous Vegetation. These plant communities frequently occurred in patches smaller than the minimum map unit and are not characteristic of any of the base map units. Pinus edulis – (Juniperus osteosperma) / Bouteloua gracilis Woodland was also not mapped as a unique map unit but was incorporated with One-seed Juniper / Bigelow’s Sagebrush Shrubland as a base map class. A summary of the base-map class distribution, as well as the distribution of the management, group, and macrogroup map classes, is presented in section 4. A key to the base map classes, crosswalked to plant community, as well as the group, macrogroup, and management map classes, is presented in Appendix E. Appendix F lists the relationship of plant communities defined in section 2 to base map classes and to the other three map schemas. Photosignatures and summaries of the characteristics of each base map class are presented in Appendix G. All base map classes have a one-to-one representation with a plant community. Six plant communities were not specifically mapped, as they could not be distinquished on the aerial photography, 29
