1. Increased grazing and dominance of an exotic pasture (Bothriochloa pertusa) affects vertebrate fauna species composition, abundance and habitat in savanna woodland

Abstract:
... The invasion of exotic pasture species into intact woodlands has the potential to affect native fauna by altering habitat structure and ecosystem function. The spread of these weeds is generally in concert with cattle grazing, so that fauna or habitat change is due to multiple interrelated causes. In this study we investigated whether the spread of the introduced pasture grass Bothriochloa pertusa ...

Abstract:
... Thickening of native shrubs is a major problem in many 'semi-arid woodlands' as significant increase in shrub density is often negatively correlated with herbaceous vegetation and leads to reduced pasture production and soil erosion. This project aimed to test the hypothesis that temporary cropping (up to three crops in 15 years) consistently increases the density of native perennial grasses follo ...

Subject:
base maps; grazing; public lands; rangelands; surveys; vegetation cover; New Mexico
Abstract:
... Data from New Mexico range survey maps created shortly after the passage of the Taylor Grazing Act in 1934 have been preserved and are being used to document changes in vegetation. The range survey data were collected at the time of a critical shift in rangeland policy and practice in federal lands of the United States. This paper describes the historical context of the post-Taylor range surveying ...
