Geospatial data for the Vegetation Mapping Inventory Project of Redwood National and State Parks

The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase. A vegetation classification and vegetation and land cover map of Redwood National and State Parks (RNSP) was created from remotely sensed and ground-verified data. The project was undertaken to provide data for the National Vegetation Mapping Inventory Program (VMI) with which to inform local NPS management and the public. Products of the project include a digital vegetation and land cover map, a taxonomic classification, quantitative floristic vegetation plot data, and report. The map employed the U.S. National Vegetation Classification (USNVC) to map 142,062 acres (57,491 hectares) of RNSP. Forty-five (45) vegetated map classes at the level of USNVC alliance and four non-vegetated land cover classes were mapped. Eighty-nine (89)% (126,796 acres) of RNSP mapped as forest or woodland, 0.9% (1,322 acres) was mapped as shrubland, 3.7% (5,294 acres) was mapped as herbaceous vegetation, 1.4% (2,053 acres) was mapped as barren, 4.2% (6,035 acres) was mapped as water, and 0.4% (562 acres) was not classified and was mapped as unknown land cover. A thematic accuracy assessment was conducted on the 30 most abundant vegetation classes, employing 512 observations throughout RNSP. The overall accuracy at the alliance level vegetation classes was found to be 65.5%. When the classes are aggregated to thematically coarser levels, the accuracy is 86.2% at the USNVC group level and 95.4% at the level of USNVC macrogroup.
