This summary layer was created by intersecting the 6th field watershed layer with the CLAMS95 (Coastal Landscape Modeling and Analysis Study) landcover layer, which was provided to the MidCoast Watershed Council by the CLAMS group at Oregon State University. This resulted in a DBF that contained the area (square meters) of each 6th Field Watershed occupied by each of the landcover categories. In addition, we created additional columns that describe the proportion of each 6th field watershed occupied by each landcover category.

Recall that there are 14 cover classes in the CLAMS95 data.

Using either the DBF or the ARCView layer you can color code each 6th field watershed by either the proportion occupied by each landcover category or by the absolute area occupied by each landcover category.

Landcover classes were determined by the CLAMS folks at OSU based on their interpretation of TM satellite imagery. The classes that they identified included: background, shadow, water, open, semi-closed, cloud, broadleaf, mixed-small conifer, mixed- medium conifer, mixed-large conifer, mixed- very large conifer, small conifer, medium conifer, large conifer, and very large conifer. (See Coastal Landscape Modeling and Analysis Study for details.)
