The Nature Conservancy's Center for Science and Public Policy in Arizona was created to engage stakeholders and expertise in applied science and policy to develop new information, ideas, and tools that can help solve some of our most pressing challenges affecting people and nature.
Riparian grasslands dominated by big sacaton (Sporobolus wrightii) once covered floodplains across the southwest, but have been reduced to some 5% of their historical extent. Sacaton stands that remain provide key resources for watershed function, wildlife, and livestock—yet may need special management to sustain these benefits. This report describes mapping methods and management recommendations that can be applied to riparian grasslands throughout the region. By examining sacaton grasslands in the Las Cienegas National Conservation Area, this project also refines methods for evaluating ecological condition, and provides managers at this site with detailed maps of both high-quality habitat and restoration needs.
Central Arizona’s Verde River is a natural resource that is critical to the regional economy, environmental sustainability, and quality of life. The river’s future is uncertain, however, as there are still unresolved issues over how we grow while sustaining a healthy river. This report examines possible futures for the Verde River within the Verde Valley and provides information for stakeholders and decision-makers on the river’s resources, economic value, and tools for promoting sustainable water management. The report also summarizes three water management case studies from around the western U.S. that characterize the range of water management options that communities have adopted.
