A Framework for Evaluating Land Use Planning Alternatives: Protecting Biodiversity on Private Land Ecology and Society
Theobald, David; Colorado State University/The Nature Conservancy; davet@nrel.colostate.edu; Hobbs, N. Thompson; Colorado State University/Colorado Division of Wildlife; nthobbs@nrel.colostate.edu.
Planning activities by local government often seek to identify areas of land that offer particularly high value for conserving biotic resources. Because private land is being developed rapidly, there is heightened concern about identifying these areas. Although general principles on setting priorities for habitat protection are emerging, substantial ambiguity remains about how to implement these principles. Here, we offer a general modeling framework for evaluating how planning alternatives could affect Critical Habitat. The framework contains four components: stakeholder involvement, spatial modeling of Critical Habitat and development patterns, analysis of alternative scenarios, and evaluation and monitoring. We illustrate this approach using a case...

Livestock grazing, habitat protection and diversity of bees and wasps in the Central Monte desert Rev. Soc. Entomol. Argent.
Vázquez,Diego P.; Aschero,Valeria; Stevani,Erica L..
Reserves aim mainly at preventing or mitigating human impacts on natural ecosystems. It is important to assess how well reserves meet this goal. We evaluated whether habitat protection offered by Ñacuñán Biosphere Reserve (Central Monte desert, Argentina) results in detectable changes in habitat structure and the species richness and composition of bees and wasps. We conducted pan trap sampling and flower visitor observations in six pairs of protected and unprotected sites. Our results suggest that thirty fi ve years of cattle exclusion in Ñacuñán have had detectable effects on habitat structure. However, these changes in habitat structure translated only into partial and conflicting effects on hymenopteran richness, and did not have detectable effects on...
