Summary

Physical and biotic conditions, along with site history, drive the composition of plants found at any site. Therefore, vegetation represents a unique biotic response to local environmental conditions at a site. Vegetation composition is in turn a major factor in determining what animals may be present. Because of the interactions between environment, plants, vegetation and community structure, vegetation distribution has long interested ecologists and natural resource managers. Documenting regional vegetation is useful for many purposes, including biodiversity assessment, conservation planning, resource management, and species distribution modeling.

Description

In 1995, the Manual of California Vegetation (MCV) introduced a quantitatively based method for classifying and mapping vegetation in California. In 2002 Department of Fish and Wildlife, Information Center for the Environment, and Aerial Information Systems used this method to develop a classification of vegetation types for Napa County, and to attribute the polygons of a new vegetation map. The complete report for this study can be viewed at: http://www.nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=14660.

Supplemental information
METHODS We digitized vegetation polygons and characterized their vegetation from the most recently available DOQQs for Napa County, flown in 1993. Map development had five stages: 1) landcover (vegetation) classification and minimum mapping unit (MMU) definition; 2) base map imagery and ancillary GIS data layers acquisition; 3) field reconnaissance to refine the classification and develop a photo interpretation key; 4) vegetation polygon delineation and attribution; and 5) field verification to assess polygon label accuracy and revise polygon definitions and the photo interpretation key, as needed. A five-person crew conducted photo interpretation, polygon delineation and attributing from February to June 2002. A two-person crew conducted field verification from early August through late October 2002. The new map was produced by on-screen digitizing over USGS Digital Orthophoto Quarter Quads (DOQQs) with the aid of ancillary digital maps. We identified the distribution of 56 landcover types, 48 dominated by natural vegetation, at the alliance or aggregated alliance level, in 28,456 polygons across 2042 km2. The effective minimum mapping unit is below one hectare. The methods used, the mapping classification system developed, and the extents of landcover types mapped are presented. In a comparison with two previous digital vegetation maps for the area, the US Forest Services CalVeg and the Gap Analysis Programs GAP maps, the Manual of California Vegetation (MCV) map had finer spatial and floristic resolution. The MCV map has 15 more vegetation types than CalVeg and 22 more vegetation types than GAP. The MCV map contains more riparian corridors and isolated wetlands, identifying 157 km2 of these types, compared to 7 km2 for CalVeg and a non-spatial result for GAP.
