Management for biodiversity and other ecosystem services from North America's rangelands has received increasing attention as recognition of the societal value of those services and payment mechanisms for them have grown. This, combined with adverse effects of livestock management on North American rangeland biodiversity and predictions of a warmer and drier climate reducing rangeland productivity, has led some rangeland scientists to call for a paradigm shift from utilitarian-driven management to biodiversity conservation management. A challenge for rangeland science is to describe management changes required for this shift and to elucidate consequent ecological and economic tradeoffs. On the basis of two criteria, direct alteration of biodiversity and alteration of one or more drivers of biodiversity, a framework of ten ecological conditions is proposed for making the transition from livestock-centered management toward biodiversity-centered management on Great Plains rangelands: (1) composition and productivity of plant communities;(2) herbivory patterns; (3) fire regimes; (4) habitat contiguity; (5) stream hydrology; (6) temporal ecological variability; (7) herbivorous mammal communities; (8) fate of ungulate production; (9) apex predators; and (10) size of management units. Reflecting trends in rangelands elsewhere around the world, a shift toward management for biodiversity on the Great Plains may be facilitated by changes underway in land ownership and by a potentially increasing number of landowners for whom livestock production is of secondary importance to lifestyle and natural amenity benefits from the land.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
