Extent and Condition of Grasslands in Arizona, Northern Mexico, and Southwestern New Mexico This file represents the final version of an assessment of the extent, condition, and distribution of grassland types in Arizona as indicated by expert interviews and field verification. Coverage includes the state of Arizona, Southwestern portions of the state of New Mexico, and the Northern portion of Sonora, Mexico.

Arizona faces critical challenges in preparing for a prosperous and sustainable future. Solving pressing challenges about water supplies, how we grow, where we build our transportation and energy infrastructure, how we sustain our environment and improve quality of life will require strong, creative leadership, institutional capacity and public support. It also will require new information and tools to help problem-solve and enable...

The objective of this project was to use a science-based approach to identify a network of Conservation Sites throughout the Ecoregion that, with proper management, would ensure the long-term persistence of the Ecoregion's biodiversity, including rare and common species, native vegetation communities, and the ecological processes needed to maintain these elements of biodiversity. The technical team convened to compile and analyze data included staff from The Nature Conservancy, Sonoran...

We integrated 12 local, state, and regional datasets that identify open space lands and sensitive biological lands. This data set is a composite or simplification of the source data sets -- the boundaries of all source records have been combined ("dissolved") into one composite record in order to facilitate analysis. Note: We did not integrate wildlife linkages data from 2 of the studies in this composite layer because we were not able to obtain permission to do so from the source agencies.

We analyzed the current distribution of 223 target species and 26 terrestrial ecological systems there, and compared them with constraints on ecosystem integrity (e.g., road density) to determine the most efficient set of areas needed to maintain current biodiversity. The resulting portfolio of 90 areas includes 12.5 million acres (5 million ha) that should be priorities for protection. Conservation strategies include protection and restoration of grasslands, restoration or maintenance of natural fire regimes, and learning more of probable effects of climate change.
