Our Mission

To preserve the Truckee-Tahoe region’s mountain character and natural environment for present and future generations.

Our Vision

Vibrant community cores surrounded by protected open space.

Our Goals

Preserve and protect open space in Truckee-Tahoe through collaboration, education & stewardship.

Sustain the authentic mountain character of the area by protecting the diversity of the environment, culture, and economy.

Advocate for responsible land use decisions & smart growth in the region.

The Tahoe region is facing a housing affordability crisis, and the Tahoe Regional Planning Agency is updating its housing policies to address it. Tahoe's land use rules must protect Lake Tahoe's clarity by law. Any changes to housing development must balance community needs with lake protection. Lake Tahoe’s housing crisis demands action now. TRPA has the power to adopt focused policies that prioritize safe, affordable, environmentally sound housing—solutions that protect people and our pristine environment. They need to hear your voice.

Wild & Scenic Film Festival On Tour, hosted by Mountain Area Preservation, is coming back to Truckee for two nights in 2026! Join MAP for back-to-back nights featuring two unique film programs at two exceptional venues, from Historic Downtown Truckee to Tahoe Donner. Mark your calendars for Friday, May 1st, at Alibi Ale Works - Truckee Public House and Saturday, May 2nd, at Tahoe Donner Alder Creek Adventure Center.

Over the last month, MAP worked really hard to secure $100k to support our mission-driven work as we enter 2026. Our members showed up to support us during two end-of-year campaigns, with support from a $50k match and 182 donors, helping us raise $100,050 to fuel open space and land use advocacy as we embark on another big year of standing up for what we love, Truckee Tahoe! 

We want to extend a huge thank you to our longtime MAP members who fueled the match: The Weakley Family, The Merrill Family Foundation, Anderson Family Fund, Daniel Haas, Peter & Ginnie Haas, Patricia Shifferle, Robert Gilliom, Cabona’s, John & Kathleen Zemaitis, and Mike & Carol Sabarese. Your continued support makes a meaningful difference for MAP’s mission and the people of Truckee Tahoe! Learn More.

Be sure to check out our spotlight on MAP advocacy over the last year on our website. Our small and mighty team tackles quite a bit, and it’s all fueled by MAP members, so thank you for being a part of our mission and helping us stand up for the Truckee Tahoe environment and community! 

The effort to save land at the eastern edge of Truckee started back in 1987, and in 2021, MAP and our partners saved 290 acres of critical wildlife habitat, while reducing fire danger in Glenshire. Now, in 2025, we are working to finalize stewardship plans and the donor kiosk. Read more in our partner update.

Save Canyon Springs | Invest to Protect

Protecting Canyon Springs as permanent open space and opening it to the public is a once-in-a-lifetime opportunity for Truckee. With the support of 700+ donors we achieved a great victory by raising $11.6 million to purchase the property. We are still raising Funds for Stewardship, Learn More.
