Southwest Biological Science Center

The SBSC provides sound science, specialized expertise, and objective and timely tools to Federal and State agencies and the public to inform land management decision-making, and support thriving landscapes for the Southwest’s abundant natural resources and vast public lands. This research assists those who manage, conserve, and rehabilitate rivers and arid regions of the nation.

Too much and not enough data: Challenges and solutions for generating information in freshwater research and monitoring

Evaluating progress toward achieving freshwater conservation and sustainability goals requires transforming diverse types of data into useful information for scientists, managers, and other interest groups. Despite substantial increases in the volume of freshwater data collected worldwide, many regions and ecosystems still lack sufficient data collection and/or data access. We illustrate...

Four-band image mosaic of the Colorado River Corridor downstream of Glen Canyon Dam in Arizona, derived from the May 2021 airborne image acquisition

In May 2021, the U.S. Geological Survey’s Grand Canyon Monitoring and Research Center acquired airborne multispectral high-resolution data for the Colorado River in the Grand Canyon, Arizona. The image data, which consist of four spectral bands (red, band 1; green, band 2; blue, band 3; and near infrared, band 4) with a ground resolution of 20 centimeters, are available as 16-bit...

Short-term ecological effects of solar energy development depend on plant community, soil type, and disturbance intensity

Solar energy is rapidly growing to decarbonize the electrical grid. Maintaining ecosystem function with solar energy generation can be promoted through construction methods that minimize negative impacts on soils and vegetation. However, the disturbance created by less-impactful construction methods at utility-scale solar energy (USSE) facilities and the ecosystem responses remain...

Riparian Vegetation in Grand Canyon: An Overview

Riparian plant communities, associated with rivers and streams, are ecologically and culturally important areas in the southwestern U.S. Despite covering less than 2% of the land area in the southwest, the resources provided by these communities make them valuable to wildlife, the public, scientists, and resource managers.
