The data points were randomly distributed stratified according to vegetation association over the project area according to protocols developed by the Program. Points were located by GPS navigation and the community information was collected at the point, without knowledge of the attributes of the vegetation spatial data. The data points were compared to the attributes of the polygon in which they were contained. Attributes of the polygons or accuracy assessment points that did not match were changed during later analysis due to errors in the AA methodology or map attribution errors. A contingency table was completed from the final dataset. To verify the accuracy of the mapped vegetation communities at Fort Laramie National Historic Site. 199808 Ground Condition Complete None Planned Fort Laramie National Historic Site, Wyoming, USA -104.577039 -104.529424 42.224866 42.190945 none National Park Service U.S. Geological Service The Nature Conservancy Aerial Information Systems Center for Biological Informatics land cover vegetation alliance association Environmental System Research Institute none Fort Laramie National Historic Site Wyoming None Standardized National Vegetation Classification System vegetation classification alliance community association Kingdom Plantae None Any person using the information presented here should fully understand the data collection and compilation procedures, as described in these metadata, before beginning analysis.

Vegetation associations were identified based on the field key and plant identification. If additional communities were found within a 50 meter radius of the plot center, they were recorded as well. During the analysis, it was concluded that some attributes were in error and changed to match the mapped attributes. This was done by examination of the aerial photographs under stereoscopic view. The attributes were in error due to 1) spatial error in the GPS derived coordinates (4-8 meters), 2) change of vegetation community due to temporal changes, or mis-identification of the community on the ground. All attributes are codes that correspond to vegetation communities and have been checked for typographical and logical errors. All points were collected and analyzed. The points were located using a military-style GPS receiver (PLGR), which has a published accuracy of 4-8 meters. Not applicable Field None Accuracy Assessment Data points were located by use of a PLGR GPS receiver by Wyoming Natural Heritage Program and Fort Laramie National Historic Site personnel. Vegetation communities were identified on the basis of a dichotomous field key and plants species present. Lab None Accuracy Assessment Accuracy assessment points were compiled into an ARCINFO point coverage and intersected with the vegetation community coverage. The resulting INFO file was exported into a text file, imported into a spreadsheet, and the attributes from the accuracy assessment and the spatial data were compared. If the attributes did not compare, an analysis of the mismatch was made and either the AA attribute or the map attribute was changed based on identification of the community on the aerial photo.

The system is organized hierarchically to support conservation and resource stewardship applications across multiple scales. The upper levels of the hierarchey are based on the physical form or structure of the vegetation (physiognomy) and have been refined from the international standards developed by the United Nations Educational, Scientific, and Cultural Organization (UNESCO). The two most detailed levels of the hierearchy are based on the species composition of the existing vegetation (floristics) and reflect the phyto-sociological standards that were originally developed by European ecologists. The vegetation classification is continually advanced through the collection and analysis of new field data and will be greatly strengthened during the course of the NBS/NPS mapping efforts.
