The vegetation image above is derived from a 1994 Landsat image which was classified by the Humboldt State University Spatial Analysis Lab (click on InfoLinks for more information about methods of classification). The area covered by the image is the Upper Jacoby Creek Calwater watershed planning unit. This watershed is characterized by dispersed early seral forests with small trees (11-16") and tree/shrub mixed dominating much of the watershed (light green with yellow patches). Small patches of orange in the photo may also be rural parcels with homesteads or pasture. A substantial portion of the very large trees (>36") remaining in the watershed in 1994 were in steeper areas at the top (east) of the watershed.
