Field data for the Vegetation Mapping Inventory Project of Golden Spike National Historic Site
2005-2012. Field data for the Vegetation Mapping Inventory Project of Golden Spike National Historic Site
This reference is an assemblage of field data collected as part the baseline vegetation inventory for the park unit. Typical files here are vegetation plot data, accuracy assessment data, field photos, PDF showing locations of vegetation plots and accuracy assessment data, and other data for this type. ecologists visited most potential map polygons in the field and recorded vegetation information on paper maps of aerial imagery. This reduced the need for a large number of quantitative plots and observation points. Sampling locations were determined by examining vegetation patterns on aerial imagery for distinctive signatures and other features, annotating the field maps with extensive notes, acquiring ground photographs, and by walking the NHS in a systematic grid pattern. The NHS was accessed to the degree possible by field crews hiking across the landscape, mapping and sampling simultaneously. The few areas that could not be accessed directly were inspected with binoculars and the dominant species and polygon boundaries were noted on the base imagery. The sampling was completed in July 2007 by NCPN vegetation mapping program and e2M staff. Three vegetation classification plots and 46 observation points were sampled and detailed field notes recorded on field maps of the imagery during the 2007 field visit. Plot and observation point data were manually entered into the GOSP Vegetation Classification and Mapping Project Database. This database is compatible with the data standards of the PLOTS Database System developed for the USGS-NPS Vegetation Mapping Program by TNC (1997). The NCPN database offers greater flexibility in overall data management than does the NatureServe PLOTS database, and is designed to accommodate all project data recorded in plots, observation points, and field photographs. Data standards were established by NCPN for all network vegetation mapping projects, allowing compatibility of data across network park units.
