There are approximately 200 species of trees and shrubs in Grand Canyon National Park. Most of these are found in the higher elevations of the park, on the South and North rims. Some of the tree species include the white fir, Engleman spruce, blue spruce, Douglas fir, corkbark fir, ponderosa pine, Utah juniper, alligator juniper, Colorado pinyon, quaking aspen, Fremont cottonwood, Gambel oak, and Arizona walnut.

Seeps and springs – the true local water of Grand Canyon – offer significant resources to visitors and wildlife alike. The water from Roaring Springs, for example, provides the park with its entire domestic water supply. And at even the smallest seeps, abundant plant and animal life grows and flourishes. In fact, the ecosystems of seeps and springs represent some of the most complicated, diverse, productive, provocative, and threatened ecosystems on earth.

The Colorado River is one of the principal rivers of the Southwestern United States and northern Mexico (the other being the Rio Grande). The 1,450-mile-long (2,330 km) river drains an expansive, arid watershed that encompasses parts of seven U.S. and two Mexican states. Starting in the central Rocky Mountains in the U.S., the river flows generally southwest across the Colorado Plateau and through the Grand Canyon before reaching Lake Mead on the Arizona–Nevada border, where it turns south toward the international border. After entering Mexico, the Colorado approaches the mostly dry Colorado River Delta at the tip of the Gulf of California between Baja California and Sonora.
Known for its dramatic canyons, whitewater rapids, and eleven U.S. National Parks, the Colorado River system is a vital source of water for 40 million people in southwestern North America.[6] The river and its tributaries are controlled by an extensive system of dams, reservoirs, and aqueducts, which in most years divert its entire flow for agricultural irrigation and domestic water supply.[7][8] Its large flow and steep gradient are used for generating hydroelectric power, and its major dams regulate peaking power demands in much of the Intermountain West. Intensive water consumption has dried up the lower 100 miles (160 km) of the river, which has rarely reached the sea since the 1960s.[7][9][10] (taken from wikipedia
