| Bryant’s Woodrats live on Cedros Island, a land-bridge island once connected to mainland Baja California. They flourish in coastal scrub, juniper scrub, chapparal, and pine forest habitats on the island's dry, steep, rugged terrain. In 1996, scientists found 97 nests, located under prickly pear cactus or other plants, in rock crevices, between boulders, or in caves. They also found woodrat runways and feces. The nests, which were 1 to 2 meters in diameter and up to a meter high, were built of sticks, cactus spines and pads, and other materials the rats gathered. In spite of this evidence of vitality, these relatively large woodrats are considered endangered, because of predation by domestic cats and because people are using the shrubs on the island for firewood, which will eventually deprive the woodrats of habitat.
