SBSC: Providing Unbiased Actionable Science & Information to Support Natural Resource Management Needs of the U.S. & Department of the Interior Priorities
The U.S. Geological Survey Southwest Biological Science Center (SBSC) is uniquely positioned in the Colorado River Basin to provide sound information, specialized expertise, and innovative tools to support the management and sustained use of natural resources on public and Tribal lands in the Southwest U.S.
WebDART: A Cutting-edge Web Tool that Evaluates Land Condition
WebDART is an online ecological assessment tool available to a wide audience that incorporates Landsat satellite remote sensing imagery, topography, geology, soil conditions, and rangeland geospatial and vegetation mapping to compare altered terrain with an unspoiled area that has similar characteristics in the same region. The tool gives resource managers, landowners, companies, and other...
Southwest Fire Innovation Landscape Network: Advanced tools for fuel monitoring and assessment of wildfire risk
The USGS Southwest Biological Science Center is coordinating the Southwest Fire Innovation Landscape Network to prepare fire and natural resource managers for rapidly changing fire landscapes by conducting research and building science-management partnerships. The network develops advanced tools and technologies to assess fuel loads and the effectiveness of fuel treatments, understand wildfire...
USGS Science Supports Management of Invasive Species
Invasive species can harm ecosystems, increase wildfires, damage forests, and outcompete native species. The US Geological Survey's Southwest Biological Science Center conducts research that provides our federal and state partners, cooperators and land managers with the tools, data and strategies to enhance biosecurity management. Scroll through the information below to read about different SBSC...
The Gemini Solar Project
The United States is developing renewable energy resources, especially solar, at a rapid rate. Although renewable energy development is widely perceived by the public as “green technology,” construction, operation, maintenance, and eventual decommissioning of facilities all have known and potential negative impacts to natural resources, including plant communities and wildlife. This is especially...
RAMPS: Restoration Assessment & Monitoring Program for the Southwest
The Restoration Assessment and Monitoring Program for the Southwest (RAMPS) seeks to assist U.S. Department of the Interior (DOI) and other land management agencies in developing successful techniques for improving land condition in dryland ecosystems of the southwestern United States. Invasion by non-native species, wildfire, drought, and other disturbances are growing rapidly in extent and...
Plant responses to drought in the southwestern United States
Land managers face challenges in the future as heat-related aridification alters the abundance, distribution, and interactions of plant species. These challenges will be daunting in the southwestern US, which is experiencing increased temperatures and prolonged droughts, resulting in reduced soil moisture in an already water-limited environment.
SBSC Tribal Partnerships
The Southwest Biological Science Center (SBSC) conducts and provides scientific information as part of our mission and Federal Trust Responsibility to strengthen relationships and build partnerships with sovereign tribal nations. Here, we highlight a few examples of projects with tribal partners.
New Tools for Modern Land Management Decisions
In an era of rapid land use changes, it is imperative that land managers and policymakers have actionable and current information available for decision processes. In this work, we seek to meet these needs through new data products and decision support tools built on digital soil mapping, new vegetation cover maps, agency inventory and monitoring data sets, and cutting-edge analytical frameworks...
The iconic giant saguaro cactus in the Sonoran Desert
The saguaro cactus ( Carnegiea gigantea) is a keystone species that grows only in the Sonoran Desert of northern Mexico and the southwestern United States. The USGS’ Southwest Biological Science Center is working to better understand the species’ biological features, its role as a keystone species that supports greater than 100 other plant and animal species, and its responses to extreme drought...
'Eastern' Joshua trees and their sole pollinators, 'eastern' Yucca moths
Did you know that moths can be pollinators? Even more amazing is that Joshua trees, the scraggly icons of the Mojave Desert, require a single moth species to ensure fertile seed production. The association between the Joshua tree and its pollinating moth is a rare example of an obligate mutualism, which means that the species are entirely dependent upon each other. Joshua trees depend on the moth...
Regional Assessment of Drought Impacts on Soils (RADIS)
Soils are the foundation of terrestrial ecosystems. They provide critical services including supplying a substrate and the nutrients necessary for plant growth, retaining moisture from precipitation, filtering contaminants from percolating waters, and acting as a sink of carbon. Healthy soils are key to sustaining both human and ecosystem health. However, global- and regional-scale disturbances...
