Text Appearing Before Image:
With land use patterns varying across the state (Fig. 5). it is not sur- prising that the change in commer- cial forest acreage has varied be- tween the geographic units: Commercial forest land Unit Change 7965 1978 Thousand acres Percent Western 2,522.6 2,534.3 + 0.5 Southwestern 1.709.7 1,597.1 - 6.6 Allegheny 3,325.4 3,282.2 - 1.3 North-Central 2,900.6 2,859.8 - 1.4 South-Central 1,721.4 1,642.0 - 4.6 Northeastern 1,220.7 1,357.3 + 11.2 Pocono 1,763.7 1,656.7 -6.1 Southeastern 1,066.8 994.3 -6.8 All units 16,230.9 15,923.7 - 1.9 The Western Unit maintained its forest area over this period. Any de- crease in forest area due to expan- sion of urban and built-up land around Pittsburgh and other urban areas was offset by a corresponding increase in forest area from marginal farmland and reclaimed surface mines. The Northeastern Unit showed the largest absolute and percentage change, registering the only signifi- cant gain of commercial forest acre- age. Our data indicate that this was primarily due to the reversion of abandoned agricultural land. Forest Agricultural and open | Urban or Built-up Disturbed
