Prickly Pear

NPS

A cactus is a member of the family Cactaceae. The park has multiple species, including cholla, prickly pear, paperspine, and hedgehog. Cactuses are adapted to conserve water. The thickened, fleshy part stores water. The spines (highly modified leaves) protect against herbivores, deflect drying winds, and provide shade. The succulent stems carry out photosynthesis. Cactuses are native to the Americas from Patagonia to northern Canada.
