Summary

The purpose of these aerial photos is to document the historical location and distribution of aspen stands and to be used in comparison older and newer photos to document changes in the size of aspen stands over time.

Description

This is a layer of aerial photos acquired from the Modoc National Forest with photo dates throughout the summer of 1994, scanned and orthorectified by the Geographical Information Center, California State Univ., Chico, with later processing by the California Department of Fish and Wildlife.It documents the location of aspen stands. It also provides the visual background for the display of polygons and the visual comparison of similar and more recent data sets. This is one of five data sets for a study investigating change in the size of aspen stands since 1946. Other available data sets are a 1946 aerial photo mosiac, interpreted polygons of individual aspen stands from 1946 and 1994, and a sample of aspen stand characteristics in 98 stands from 2002. Geographic extent of the imagery: The study area is the Warner Mountains south of State Highway 299.
