Field data for the Vegetation Mapping Inventory Project of Black Canyon of the Gunnison National Park
2001-2010. Field data for the Vegetation Mapping Inventory Project of Black Canyon of the Gunnison National Park
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. The mapping area is 22,989 hectares (56,807 acres), encompassing the entire park as well as an environs of adjacent public and private lands. Ecologists and photo interpreters identified vegetation alliances and plant associations for BLCA and determined how best to map them using 1:12,000-scale, true color aerial photography and digital orthophotography. The team collected vegetation and environmental data from 112 classification plots and 16 observation points. Supplemental fuels data were collected during the project in Gambel oak, pinyon-juniper, ponderosa pine, Douglas-fir, and quaking aspen communities. Assessment of map accuracy entailed sampling of another 762 data points. Fieldwork and mapping were completed between 2001 and 2004. Analysis of the vegetation data revealed 77 National Vegetation Classification plant associations, vegetation alliances, or park special vegetation types within the park and environs, 56 of which are shared with the adjacent Curecanti National Recreation Area (CURE). Twenty-eight plant associations were documented exclusively from accuracy assessment data, the remainder from vegetation plots and observation points.
