This is the third and final year of this project. In 1990 and 1991 we concentrated our efforts at Natural Bridges National Monument and Canyonlands National Park. In 1992, we performed work at Natural Bridges National Monument, and at Arches National Park. At Natural Bridges we sampled plant grids and small mammal grids along sections of canyon bottom containing or lacking a hiking trail to determine if the trail was influencing the distributions or abundances of plants or animals in the canyon bottom. We collected data in May and June. We sampled the area between Sipapu Bridge and Kachina Bridge (area containing the well used hiking trail), and an area about 3 kms long above Sipapu Bridge (area lacking a well used trail).
