A radioed male tortoise in the Santa Rosa Mountains, CA eating a beavertail prickly pear cactus. During the extreme drought conditions we are experiencing, that is the only food available for them with any moisture. They have to cope with all the little spiny gloccids (hair-like spines) that cover the pads of the cactus. Video provided by Dr.

USGS conducts vegetation and soil drought and climatic research at long-term study sites in Canyonlands National Park, Utah in partnership with the National Park Service. This photo shows a site tour of a protected grassland that has been monitored by the USGS since 1996, with 2025 marking the 30th year of continuous data collection.

Panorama photo of Lake Powell taken from the water, with rocks in the distance. Some of the "bathtub ring" is visible on the rocks from mineral deposits left when the water level dropped.

An eastern Joshua tree (Yucca jaegeriana) inflorescence (flowers) with a Yucca moth (Tegeticula antithetica) trap. SBSC is studying the ecology of the eastern Yucca moth, which is the obligate pollinator of eastern Joshua trees, to determine how climate change affects the emergence of blossoms and eastern Yucca moth visitation.
