About this Collection
In 1926, the U.S. National Forest Service began a natural vegetation survey of California and those portions of Region 5 National Forests and adjacent areas that extended into Nevada and Oregon. The initial purpose was to provide data in support of statewide land use and fire protection policy development. The California survey was headed by A.E. Wieslander, Associate Silviculturist with the USFS California (now Pacific Southwest) Forest and Range Experiment Station. The project became known as the Wieslander Vegetation Type Map (VTM) Survey.
