Mount Lemon
Elevational gradient is an ecological pattern where trends in biodiversity occur at different elevations. Mountains are considered "hotspots" of biodiversity. Depending on a certain elevation level, ecosystems change. Mount Lemmon is a prime example of such a pattern. At lower elevations, Saguaro cacti pervaded the landscape. At higher elevations, the cacti were basically nonexistent. Instead, pine trees dominated the scene. Human activity such as continuing land development (habitat destruction) pose a threat to unique ecological phenomenon such as the one existing on Mount Lemmon.
