Natural Features & Ecosystems
The entire park area is considered to be semi-arid desert, but distinct habitats are located at different elevations along the 8,000 foot elevation gradient. Near the Colorado River, riparian vegetation and sandy beaches prevail. Just above the river corridor a desert scrub community exists complete with a wide variety of cacti and warm desert scrub species. A pinyon pine and juniper forest grows above the desert scrub up to 6,200 feet, while between 6,200 feet and 8,200 feet ponderosa pine is abundant. On the North Rim at elevations above 8,200 feet, a spruce-fir forest tops out the park.
As in all natural habitats, the type and abundance of organisms is directly related to the presence or absence of water. The Colorado River and its tributaries, as well as springs, seeps, stock tanks and ephemeral pools provide oases to flora and fauna in this semi-arid southwest desert area.
The arid climate has been a benefit to the Paleontological resources of the park. The dry climate has been instrumental in preserving many prehistoric fossils deep within caves in Grand Canyon's geologic formations.
