We investigated the efficiency of DK-1 and Macabee® pocket gopher (Geomys bursarius) traps placed in lateral tunnels in both open and closed tunnel sets in rangeland and nonirrigated alfalfa fields in Nebraska. We observed no statistical difference between the traps in capture efficiency when used in open, versus closed, tunnel sets. Trapping of pocket gophers was more effective in rangeland (p...

This article examines the history of rangeland management on the El Rito District of the Carson National Forest in northern New Mexico. The area became part of the U.S. Forest Service system in the late nineteenth century, when Mexican land grants in the area were not confirmed by U.S. courts. In the 1940s, the Forest Service implemented a series of grazing restrictions in the district. The art...

The encroachment of agricultural practices into traditional rangeland areas of north-eastern Morocco is considered by some to have negative impacts in both the agro-pastoral communities that utilise these ranges and the surrounding physical environment. Indicating the extent and location of such land use changes provides resource managers with valuable information on which more sustainable deve...

The Water Erosion Prediction Project (WEPP) is a physically based erosion model for applications to dryland and irrigated agriculture, rangeland, and forests. U.S. Forest Service (USFS) experience showed that WEPP was not being adapted because of the difficulty in building files describing the input conditions in the existing interfaces. To address this difficulty, a suite of Internet interface...

This paper reviews the predictions and management implications of two current paradigms in the ecology and management of arid and semi-arid rangelands. The equilibrium model stresses the importance of biotic feedbacks such as density-dependent regulation of livestock populations and the feedback of livestock density on vegetation composition, cover and productivity. Range management under this ...
