Over 1000 species of vascular plants grow in Grand Teton National Park and the surrounding area. Soil conditions, availability of moisture, slope, aspect, and elevation all determine where plants grow. Plants that require similar conditions are often found growing in the same area. These associations form various plant communities. It is useful to divide the plants of Grand Teton National Park into the following communities: sagebrush flats, riparian corridors and wetlands, forests, and alpine areas.

The valley floor of Jackson Hole is comprised of loose rocky soil that allows water to percolate through easily. Silvery-green big leaf sagebrush blankets the valley. Although at first glance it appears that only sage grows on the flats, this area is remarkably diverse.

Moisture-loving plants find suitable growing conditions along the Snake River, its tributaries, and other wetland areas. Narrow leaf cottonwood and willows, both of which thrive in wet areas, grow along the watercourses, creating ribbons of bright green across the landscape. Wet meadows provide the conditions suited to grasses, sedges, and wildflowers.

The canyons, mountainsides, and ridges formed of glacial debris, called moraines, contain soils capable of holding moisture. These conditions support the growth of trees. Conifers dominate these areas, coloring the slopes a dark green.

Although they appear gray and lifeless, the high alpine reaches of the park support plants specially adapted to the harsh growing conditions found there. Wind, snow, lack of soil, increased ultraviolet radiation, rapid and dramatic shifts in temperature, and a short growing season all challenge the hardy plants that survive here. Most plants adapt by growing close to the ground in mats like the alpine forget-me-not.

Uinta Ground Squirrel

Did you know that Uinta ground squirrels, sometimes mistaken for prairie dogs, hibernate up to eight months a year? These animals leave their burrows in March or April to inhabit the sagebrush flats, but may return by the end of July.
