Buffelgrass-Integrated modeling of an invasive plant

Buffelgrass (Pennisetum ciliare) poses a problem in the deserts of the United States, growing in dense stands and introducing a wildfire risk in an ecosystem not adapted to fire. The Invasive Species Science Branch of the Fort Collins Science Center has worked with many partners to develop a decision support model and a data management system to address the problem. The decision support model evaluates potential strategies for resource use and allocation. The data management system is a portal where users can submit, view, and download buffelgrass data. These tools provide a case study showcasing how the FORT is working to address the urgent issue of invasive species in the United States.

Improved ground-based remote-sensing systems help monitor plant response to climate and other changes

Scientists at the U.S. Geological Survey are improving and developing new ground-based remote-sensing instruments and techniques to study how Earth’s vegetation responds to changing climates. Do seasonal grasslands and forests “green up” early (or late) and grow more (or less) during unusually warm years? How do changes in temperature and precipitation affect these patterns? Innovations in ground-based remote-sensing instrumentation can help us understand, assess, and mitigate the effects of climate change on vegetation and related land resources.

Mines and mineral processing plants in the United States

Although minerals are vital to our way of life, many of us take them for granted. Hundreds of the things that we do each day - from driving a car to watching television or working on a computer - depend on products made from minerals. It takes about 3 tons of coal and 10 tons of nonfuel minerals, elements, and mineral products in the United States per person each year, just to maintain our lifestyle (U.S. Bureau of Mines, 1991).
