Agate Desert is a prairie near White City in southern Oregon, not a true desert but a landscape named for the agate, petrified wood, jasper, and other minerals found there. Its defining feature is a network of seasonal vernal pools that fill in winter and spring, create small wetland habitats, and leave rings of wildflowers when they dry. These pools and prairies support rare species, including the Hairy Water Flea, found nowhere else, and endangered plants such as big-flowered woolly meadowfoam and Cook's lomatium. After heavy alteration by Camp White and later development, preservation efforts now focus on restoring native grassland and protecting this unusual ecosystem.
