Table 1. Areas of vegetative cover types in the Southern Pacific Rainforests, physiographic area 93. U.S. forest coverages are taken from USFS FIA data, nonforest cover types are modified from USGS data. Habitat coverages with superscript * are combined from both databases by adding USGS coverage in the "nonforest" section of the USFS database. Canadian cover types are taken from CCRS landcover database.
