Description:
Wieslander Vegetation Type Mapping, Santa Barbara County, California.

In the 1920s and 1930s Albert Everett Wieslander and several others explored much of California's wilderness sampling vegetation, taking photographs, collecting plant specimens, and drawing detailed maps of what they found. These data represent a snapshot of California's vegetation in the early 20th century, and are a valuable resource for comparative and conservation ecology. 

The ultimate goal of the original VTM project was to create vegetation type maps, but several other types of data were collected in the process. Vegetation plots, in which crews collected data on species composition, depth of leaf litter, tree size, and other variable, were used to validate the broad zones of vegetation they designated from high vantage points. The plot locations were marked on USGS topographic quadrats for reference. Additionally, sample specimens were collected and placed in the University and Jepson Herbaria, many of which remain there today. Photographs of many distinct locations were taken, the locations of which were also recorded on topographic quads (unfortunately many of the original photos maps were lost). Finally, they created vegetation maps, drawing broad zones of single or mixed stands in colored pencil directly onto USGS topographic quads.

This dataset was selected by location to a buffered boundary of Santa Barbara County, California.
