I am a cactus with round branches covered completely in spines. I may look like a fuzzy teddy bear, but my spines are sharp! Desert woodrats use my spines for protection, guarding their burrows with my branches when they fall off to keep the coyotes and foxes away. My spines have been used as tools and if you are careful to pick through my needle sharp spines, my buds and the fruits are edible. I love hot and dry places, which may make me resilient to climate changes but my ability to disperse to new areas when temperatures are not suitable will be important for my future.
