Land Conservation

Conservation and reforestation efforts started in Little Cottonwood Canyon in 1933. The Alta Environmental Center carries on that tradition today.

Stewardship and revegetation efforts at alta, since 1933.

The Alta Environmental Center (AEC) was created in 2008 to guide the ski area's sustainability efforts and look after the natural environment in which we operate. Whenever a modification to the land is made at Alta Ski Area, whether it be laying new infrastructure, installing new equipment, or any recreational action that disrupts the land, equal restoration efforts are put back in to help in conserving the Alta environment.

Restored Wetlands

The installation of the new Supreme lift in 2017 resulted in the permanent displacement of 60 square feet (sf) and temporary disturbance of 560 sf of wetland in the Albion Fen within Albion Basin. The Supreme project includes the restoration of disturbed wetlands and the potential creation of 4,000 sf of new wetlands. Restoration/creation of wetland includes: 520 sf of wetland is actively being restored through the removal of three old Cecret lift towers; 1,480 sf of new wetland is being restored with a swale at the Fen’s outlet; another 2,000 sf of new wetland is being restored in the Supreme base terminal excavation cut.

Alta Ski Area and Forest Service are pleased with the progress of the restoration and the new wetland areas. Disturbed wetland areas continue to be restored using nearby wetland soils and plant resources and recovery continues to be observed. Restoration efforts by Alta over the 2019 summer included:

  • Planting 857 native riparian & wetland flowers, and 1,715 upland flowers from the base to the top of the Supreme lift, totaling 2,572 flowers all grown from hand-collected seed (plan includes ~3,000 plants annually through 2020).
  • Transplanted approximately 100 sf of native plants into the disturbed areas (to be repeated again in 2020).
  • Seeded approximately 1,500 sf with native sourced wetland seed from the Fen.

invasive plant management

One of the primary threats to the health and ecological balance of the Alta environment is the spread of invasive, non-native, noxious plant species. Invasive species thrive in highly disturbed areas and often out-compete native vegetation due to invasive species' ability to grow rapidly and establish quickly. Alta Ski Area has partnered with the Cottonwood Canyons Foundation (CCF) and Friends of Alta (FOA) to help with invasive plant management within the ski area, and within the Town of Alta. CCF collaborates with Salt Lake City Public Utilities, Alta Ski Area's watershed regulator, on invasive plant management within the cottonwood canyons.

In 2019, the Alta Environmental Center surveyed 101 Acres of Alta Ski Area for invasive plant species. Over the course of the summer and fall, the AEC, partner organizations and volunteers successfully treated 75% of the invasive plant surveyed areas.

Trees Planted

The earliest documented reforestation efforts at Alta were completed by the Civilian Conservation Corps (CCC) in 1933. The CCC was a work relief program that was formed from Franklin D. Roosevelt's New Deal legislation to help combat high unemployment rates during the Great Depression. Since then, trees have been planted to some extent at Alta Ski Area almost every summer. Tree seedling harvest and tree planting events provide the public with an opportunity to get their hands dirty and contribute to ongoing conservation efforts within the ski area. Seeds for plants and trees are harvested at the end of every summer by AEC staff within the ski area. Harvesting seed from the ski area for revegetation and restoration efforts takes work but generally results in more successful plant and tree growth since the seed came from Alta. Seed collection efforts are defined yearly based on where revegetation and restoration needs to take place on the mountain. The aspect, elevation, vegetation type, and other characteristics are considered when deciding what seed will be harvested annually.

After harvested, the seed is taken to nurseries to grow over the winter. Eventually, the seeds provided to the nurseries are returned as tree and plant seedlings for planting within the ski area.

Once the seeds are collected and sorted, they go to local nurseries where they grow for 6 months to three years depending on the species, until they are strong enough to be planted and survive. Once the plants are ready, species that are a good match for a disturbed site are planted.

Since 1991, Alta has recorded the number of plants and trees that have been planted on the slopes of Alta.

  • 39,324 trees planted since 1991
  • 69,574 plants planted since 1991
