Changes in Use of Three Oregon, USA, Wildernesses

摘要

Several studies have suggested that use of wildernesses within national forests is declining. Data from three wildernesses in Oregon (based on mandatory permits and voluntary registration) indicate that between 1976 and 1991 in two areas and between 1980 and 1993 in another area the number of recreational visitor days (RVDs) has de- clined between 23/100 and 63/100. However, the number of visits has remained roughly stable in one area and more than doubled in the other two.
