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.

SBSC researcher Mary Kathryn Busby sets traps on a Joshua tree in NW Arizona, April 2022. SBSC is studying the ecology of the Yucca moth (Tegeticula antithetica), which is the obligate pollinator of eastern Joshua trees (Yucca jaegeriana) to determine how climate change affects the emergence of blossoms and eastern Yucca moth visitation.

Starting in 2017, U.S. Geological Survey (USGS) researchers and land managers are co-producing a network of restoration field trial sites on Department of Interior (DOI) and surrounding lands in the southwestern U.S. The network systematically tests restoration treatments across a broad range of landscape, soil, and climate conditions.
