They are refuting the causality of notions normally attributed to pastoralism, such as land mismanagement and degradation. They are also showing how extensive pastoral production has been underesti...

Globally, new combinations of introduced and native plant and animal species have changed rangelands into novel ecosystems. Whereas many rangeland stakeholders (people who use or have an interest in rangelands) view intentional species introductions to improve forage and control erosion as beneficial, others focus on unintended costs, such as increased fire risk, loss of rangeland biodiversity,...
Rapid human population growth and habitat modification in the western United States has led to the formation of urban and exurban rangelands. Many of these rangelands are also home to populations of black-tailed prairie dogs (Cynomys ludovicianus). Our study aimed to compare the vegetation composition of an urban and exurban rangeland, and explore the role that prairie dogs play in these system...

Mountain pocket gophers (Thomomy's talpoides) and plains pocket gophers (Geomys bursarius) are a problem to rangelands in Colorado. A new chlorophacinone (50 ppm) pelleted bait was applied to active burrow systems by hand baiting. Efficacy on the Geomys plot was 100%, while 94.73% of the Thomomys were controlled with the product. Introduction Pocket gophers, of the family Geomyidae, are indigen...
