Natural landscapes in the Southwestern United States are changing. In recent decades, rising temperatures and drought have led to drier conditions, contributed to large-scale ecological impacts, and affected many plant and animal species across the region. The current and future trajectory of climate change underscores the need for managers and conservation professionals to understand the impacts of these patterns on natural resources. In this regional assessment of the Southwest Climate Change Initiative, we evaluate changes in annual average temperatures from 1951–2006 across major habitats and large watersheds and compare these changes to the number of species of conservation concern that are found within these...

Grasslands of the Sky Islands region once covered over 13 million acres in southeastern Arizona and adjacent portions of New Mexico, Sonora, and Chihuahua. Attempts to evaluate current ecological conditions suggest that approximately two thirds of these remain as intact or restorable grassland habitat. These grasslands provide watershed services such as flood control and aquifer recharge across the region, and continue to support dozens of species of concern. Prioritizing conservation interventions for these remaining grassland blocks has been challenging. Reliable data on condition and conservation value of grasslands in the region have not been systematically summarized. State and national boundaries further complicate...

The Nature Conservancy has been a leader in spatial conservation planning for many years. The primary planning tool used by the Conservancy for landscape-scale conservation planning over the past decade has been Ecoregional Assessments. Our United States Ecoregional Assessments identify priority areas for conservation within the United States. This includes data from 67 Ecoregional Assessments, which identified over 9,000 conservation priority areas. Importantly, this dataset contains the conservation targets that we hope to conserve within these priority areas. Conservation targets include both species and habitat types (e.g. plant communities; ecosystems). Our dataset includes 8,507 unique species and 6,633 habitat...
