Evaluation of Forest Susceptibility to the Gypsy Moth across the Coterminous United States
TABLE 5
Total land area covered by forests in three susceptibility classes by state. Numbers directly under land areas in each susceptibility class are areas expressed as a percentage of total forested area for the state. The second number below each susceptiblity class area is the area expressed as a pecentage of the total state area (when inventory data were incomplete, this percentage was expressed as a proportion of the land area for all counties in the state were inventory data were available).
