This image portrays stand replacement level disturbance sites (minimum 2 ha) for the forested portion of the study area. Disturbances are classified according to cause and date. Purpose: To provide a highly accurate, high spatial resolution disturbance map of western Oregon for use in forest & wildlife management and regional ecology studies. Supplemental_Information: Procedures_Used: Over fifty separate LANDSAT images dating from 1972-1995 were combined and analyzed to detect forest cover change during five time periods. The analysis took place on 28 different pieces, assembled so that each piece had only one image for each date. After change pixels were identified for each piece, the pieces were mosaiced, smoothed, and filtered to a minimum mapping unit of 2 ha. Disturbance by fire was separated from disturbance by harvest by visual inspection and expert knowledge. For a full explanation, see: Cohen, W. B., M. Fiorella, J. Gray, E. Helmer, and K.

This is the first public version and is the current official version. Supplemental_Information: References: Cohen, W. B., M. Fiorella, J. Gray, E. Helmer, and K. Anderson. 1998.
