Fish distribution in Umpqua National Forest. The cover was built at two locations and by two people. Cottage Grove prepared the Cottage Grove district fish distribution and the Supervisors office prepared the fish distribution for Tiller, North Umpqua, and Diamond Lake districts. The SO then merged the two layers together. The fish distribution layer was developed using the existing stream layer, then identifying those streams and stream breaks for each fish species. The streams that don't have any fish distribution were deleted fom the layer. Arcview was the program used to create the layer utilizing heads-up digitizing to identify the breaks. This cover was built at a map scale of 1:24000.

This dataset depicts riparian reserve management areas as defined under a Record of Decision for the Umpqua National Forest. The Record of Decision is on file at the Umpqua National Forest Supervisor's office. The riparian reserve areas are defined as buffers from streams and waterbodies of varying distances based on the class of the waterbody and the average timber height and ground slope within each fifth-field watershed. The distances used to create define these buffers are contained within the attributes of this dataset.

This dataset represents fire boundaries on the Umpqua National Forest for significant, large fires that occurred between 1987 and and 2003. Many smaller fires that occurred on the Umpqua National Forest are not included in this dataset.

This dataset depicts harvest activity on the Umpqua National Forest in Oregon, collected under the NRIS FACTS system. Critical attributes are either missing (activity date) or not defined by the Umpqua National Forest, so this dataset is presented until a better dataset is obtained.

Plant series for the Umpqua National Forest. This layer was developoed from ecology plot data and analysis of each plot's physical characteristics (slope, elevation, aspect). The characteristics were used to map the forest into several series used for classification. Each polygon attribute represents the plant series as defined by the physical characteristics of the polygon. These polygons were manusctipited on 1:24000 mylars and scanned and edited in LTPlus. This cover was built at a map scale of 1:24000.

The Fish_AnadromousWsh feature class contains polygon corporate data which depicts the range of anadromous fish within watersheds. This feature class is a product of the Pacific Northwest Region Coverage to Geodatabase Conversion Project in an effort to standardize data throughout the Region.
