Table 1. Areas of vegetative cover types in the Eastern Spruce-Hardwood Forest, physiographic area 28. U.S. forest coverages are taken from USFS FIA data, nonforest cover types are modified from USGS data. Water coverage is combined from both databases by adding USGS water in the "nonforest" section of the USFS database. Canadian coverages are taken from the CCRS landcover database..
