Vegetation sampling was performed by Peter Bowman. Accuracy assesement was performed by Sue Gawler from NatureServe. The shapefile depicts point locations of vegetation classification sampling points and point locations for accuracy assessment observation points. Plot locations were recorded with a WAAS-enabled GPS unit. A GPSMap60CSX unit was programmed with coordinates of the selected accuracy assessment sampling locations. Data were reformatted to match Plots V3.2 by the USGS/CSS/Core Science Analytics and Synthesis. 200409 ground condition Complete None planned Saint-Gaudens National Historic Site and environs -72.380129 -72.365661 43.502717 43.490721 National Park Service Theme Category Thesaurus Vegetation ISO 19115 Topic Category biota none Vegetation Map Association level Vegetation Classification vegetation plots thematic accuracy assessment National Park System Unit Name Thesaurus Saint-Gaudens National Historic Site National Park System Unit Code Thesaurus SAGA none Saint-Gaudens National Historic Site Cornish New Hampshire none 2004 None Standardized National Vegetation Classification System vegetation classification alliance community association Kingdom Plantae None None Sue Gawler NatureServe Regional Ecologist mailing address

Bowman, New Hampshire Natural Heritage Bureau 201205 Report Natural Resource Technical Report NPS/NER/NRTR--2012/584.1 http://www.usgs.gov/core_science_systems/csas/vip/parks/saga.html Dataset contains no duplicate features. Point locations for all 25 plots and 17 accuracy assessments are included. Each accuracy assessment point is representaed by one point in the shapefile. All points fall within vegetation association polygons. Twenty-five vegetation plots were sampled for this vegetation project during August and September of 2004. Field survey methodology followed the standards of the USGS/NPS Vegetation Mapping Program (http://biology.usgs.gov/npsveg/), using NatureServe field forms adapted for the project. At least three vegetation plots were placed in each type identified in the reconnaissance, except where limited spatial extent prevented it. Areas classified as Anderson Level II (modified) categories were not sampled. The plot data collection was carried out by Pete Bowman. Vegetation structure is documented as total cover, stratum height, and characteristic species for each stratum. Then, segregated by stratum, each species' cover was recorded in the applicable cover class, as the class midpoint. A seven-class cover scale was used. Data also included diameter at breast height (dbh) measurements for trees in the plot. Additional data were collected on landscape position, adjacent vegetation types, presence and abundance of non-native invasive species, and disturbance types. Because of archaeological restrictions within the park, soil disturbances are not permitted, and information collected on soils was limited to what was visible at the surface. Digital photographs were taken of most vegetation associations. The location of each plot was recorded with a global positioning system (GPS) unit, with the datum set to North American 1983 (Conus) and the coordinate system set to Universal Trans-Mercator (UTM) zone 18. The GPS unit was WAAS (Wide-Area Augmentation System) enabled and provided real-time differential correction. Vegetation association-level data recorded in the plot forms were crosswalked to the US National Vegetaiton Classification System by NatureServe'sRegional Ecologist, Sue Gawler in 2004. 2004 Peter Bowman New Hampshire Natural Heritage Bureau Ecologist mailing address

Concord NH 03301 USA (603) 271-3623 x427 pbowman@dred.state.nh.us 9-5 Thematic accuracy has several objectives including to asssess the data's suitability for a particular application, to inform the map producers to learn more about data errors and improve the mapping process, and conform to production standards. Accuracy assessment (AA) sampling design followed the guidelines provided in the NPS Vegetation Mapping Program (The Nature Conservancy 1994) manuals with respect to the number of AA points sampled and their distribution across park polygons. The sampling design called for 20 points during the 2006 field season. AA sampling coordinates were selected by generating random points within the minimum and maximum easting and northing UTM coordinates of the park's extent. During October 2006, 17 accuracy assessment point was located in the field using a GPSMap60CSX unit. Points were then buffered at a distance of 10 meters from the polygon border to exclude ecotonal areas that may be of ambiguous classification.The datum on the GPS units was set to North American 1983 (Conus) and the coordinate system was set to Universal Trans-Mercator (UTM) zone 18. The vegetation association at the point was then determined using the dichotomous key and the detailed vegetation descriptions. The dominant plant species in each stratum, environmental attributes, surrounding vegetation associations, rationale for classification and other comments were noted on a field form. After field work was completed, data from the 17 accuracy assessment points were entered into the NatureServe PLOTS 2.0 Database System on a Microsoft Access platform. Vegetation associations were identified using the vegetation key developed for the park. AA results were analyzed using a sample missclassification matrix. Overall accuracy and Kappa index were calculated following the Accuracy Assessment Procedures-USGS/NPS Vegetation Mappiong Program manual (The Nature Conservancy 1994). 2006 Sue Gawler NatureServe Regional Vegetation Ecologist mailing and physical address
