1991 , from 4.4 billion cubic feet to 5.5 billion cubic feet— 0.7 percent of the 

 growing stock inventory. Annual mortality averaged 4.2 billion cubic feet 

 between 1962 and 1986. Softwood mortality was up 17 percent between 1986 

 and 1991 . Hardwood mortality was up 34 percent. 



— Total forest growth on timberland declined about 2 percent between 1986 and 

 1991— the first decline since 1952. All of the decline was attributable to 

 softwoods. In the South, softwood removals exceeded growth by 14.1 percent in 

 1991 . This is the first time since 1952 that softwood removals have exceeded 

 growth in the South. Because of a decrease in removals in the Pacific Coast 

 region, timber growth exceeded removals by 14 percent in 1991 , the first time 

 that growth has exceeded removals in this region since 1952. For the Nation as 

 a whole, the growth-removal ratio for softwoods was 1 .09 in 1991 . 



— The number of species listed as threatened or endangered has increased by 

 197 to 728 since the 1989 Assessment. Endangered biota are not 

 homogeneously distributed across the United States, but are concentrated 

 primarily in the Southeast and Southwest. High species endangerment is 

 associated with land use intensification, drought-stress climate, high levels of 

 species richness, and endemism. 



The Demand/Supply Outlook for Renewable Resources Is Changing 



— If current demographic trends continue, the proportion of the population that is 

 white and non-Hispanic will decline from 75 percent in 1992 to 56 percent by 

 2040 (fig. 3). The median age of the population will increase from 33 in 1990 to 

 43 in 2040, and the proportion of the population living in urban areas is 

 expected to increase. These trends suggest that important changes in both 

 participation rates and patterns of outdoor recreation are likely. The impacts of 

 increased customer diversity are likely to be most significant in and near urban 

 areas. For example, African Americans generally participate less in activities 

 that ordinarily take place in a wildland setting, but participate more in sports
