Aspen Stands - Warner Mountain [ds112]

This dataset displays aspen stands in the Warner Mountains south of State Highway 299. The 1946 and 1994 data are presented as polygons depicting aspen stands derived from aerial photos taken in 1946 and 1994, respectively, while the 2002 data includes the aspen stand delineations and their corresponding vegetation data (i.e., size distribution of aspen, the canopy and shrub cover, the number of species of grasses and forbs, and the ratio of conifers to aspens). The polygons ranged in size from less than 0.2 acres to more than 1,130 acres. There are 2103 records, one for each aspen stand mapped and sampled. All data were collected and summarized by Aaron Di Orio, California Department of Fish and Wildlife. This is one of three data sets for a study investigating change in the size of aspen stands since 1946. Other available data sets are 1946 and 1994 aerial photo mosaics.
