Desert Landscape Conservation Cooperative Boundary delineates the spatial extent of the DLCC. The vector boundary is available as both a shapefile and KML file. This is a derivative product of the LCCs shapefile produced by the U.S. Fish and Wildlife Service, accessed from http:/http://www.fws.gov/GIS/data/national/ in 2014.To access the KML file, click on the ScienceBase URL and then select Open in Google Earth (KML).

Final Report BOR R12AP80915 FY12: Defining Ecosystem Water Needs of the Upper Gila River and Assessing the Impacts of Climate Change
Final Report Executive Summary: The Nature Conservancy and a team of 14 academic partners (the project team) received funding from the Bureau of Reclamation’s WaterSMART program and the Desert Landscape Conservation Cooperative in 2012 to conduct this Gila River Flow Needs Assessment. The assessment describes the existing condition of the Gila River in the Cliff-Gila Valley and examines the potential impacts of CUFA diversion and climate change on the riparian and aquatic ecosystem. The project team was assisted by 35 academic, agency and consulting scientists who have expertise in some aspect of the Gila River’s hydrology and ecology. This larger team of scientists provided input on a review draft of this assessment...
Final Report BOR R13AP80034 FY13: (A Study of Climate Change Impacts on Water Quality and Internal Nutrient Recycling in Lake Mead, Arizona-Nevada)
Southern Nevada Water Authority will add new modeling and analytical capabilities to tools developed as part of a previous WaterSMART Climate Analysis Tools Grant that assessed impacts of climate change on water quality and sediment transport in Lake Mead. Project results are intended to increase an understanding of how water quality characteristics and nutrient levels in Lake Mead may be affected by climate change.
Quantitative and Predictive Analysis: Landscape Connectivity of Isolated Waters for Wildlife in the Sonoran Desert
Executive Summary: We provide an analysis of Sonoran Desert water network connectivity to inform managers of current conditions for target wildlife and how the connectivity will change as the landscape becomes more water limited.Climate change is expected to lead to fragmentation of the network, increasing coalescence distance by 8% and reducing the persistence and overall number of waters on the landscape. Identification of key water sites, ranked by network connectivity metrics, are presented in Appendix B. Wetland number under our scenario of water limitation will decline by 43% reducing network resilience.Anurans and Caudates, although varying in ability to disperse, generally experienced reduced connectivity...
Final Report: Data provision and projected impact of climate change on fish biodiversity within the Desert LCC
The four primary objectives of this project were to: (1) compile a dataset of fish occurrence records for the entirety of the Rio Grande drainage in the US and Mexico; (2) improve that dataset by reformatting dates, synonymizing species names to a modern taxonomy, georeferencing localities, and flagging geographic outliers; (3) for those species with sufficient data for modeling, create species distribution models (SDMs); (4) use the environmental conditions determined via those models to project the species distributions into the future under two climate scenarios. To accomplish those objectives, we compiled 495,101 fish occurrence records mined from 122 original sources into a single database. We then, on the...
Resources on the Effects of Wildfire and Climate Change on Avian Communities and Habitats in the Sky Islands, Arizona
Executive summary: The avifauna within the Sky Islands of southeastern Arizona includes species found nowhere else in the U.S. Thus, birdwatchers from across the globe visit the region, providing a vibrant state and local ecotourism industry. RMRS scientists initiated a study in the 1990s on avian distribution and habitat associations within the Sky Islands. Since then, the region has been under increased stress from ongoing droughts and wildfires, likely associated with climate change. By re-measuring vegetation and bird populations in 2014 following wildfires and applying climate change models, we will assess the singular and synergistic effects of climate change and wildfire and provide strategies for managing...
R12AP80911 Final Report: Alamosa Creek and the Cañada Alamosa Community: Aligning ecological restoration and community interests through active experimentation
Final Report Abstract: More than half of the world’s population relies upon monsoonal rainfall that supports agriculture. While in many locations climate change is resulting in less moisture from fewer winter storms and more intense summer precipitation events, rural working landscapes (agricultural managed systems) are struggling to recover from increasingly extreme droughts and floods. The Cañada Alamosa watershed, a 420,000 acre in southwestern New Mexico (see figure 1), faces contemporary resource challenges common to the Southwest; overgrazing and fire suppression have led to a loss of deep soils and vegetative cover. This area’s traditional cultural practices of managed stormwater flooding of the historic...
