Spatial and temporal variation in soil and vegetation impacts on campsites Spatial and temporal variation in soil and vegetation impacts on campsites
We studied the impacts of camping on soil and vegetation at Delaware Water Gap national Recreation Area. We assessed the magnitude of impact on campsites that varied in amount of use and in topographic position. We also evaluated change over a 5-yr period on long-established, recently opened, and recently closed campsites, as well as on plots subjected to experimental trampling. Campsite...

Trail degradation as influenced by environmental factors: A state-of-the-knowledge review Trail degradation as influenced by environmental factors: A state-of-the-knowledge review
Excerpt: Human use and misuse of land has been causing extensive degradation of the very natural resources on which we depend. National parks, wilderness and other protected natural or semi-natural areas (referred to as natural areas hereafter) represent efforts to preserve our natural heritage from further exploitation. Such areas also provide outstanding recreational, research, and...

Environmental auditing: Capabilities and management utility of recreation impact monitoring programs Environmental auditing: Capabilities and management utility of recreation impact monitoring programs
A recreation impact monitoring system was developed and applied in 1984?1986 and in 1991 to all backcountry river-accessed campsites within Delaware Water Gap National Recreation Area, Pennsylvania and New Jersey. Results suggest that actions implemented by park managers in response to problems identified by the initial survey were highly effective in reducing resource degradation caused...
