Our Spring Full Moon Jazz is FULL! Thank you to the 300+ who emailed their RSVP!We are sorry that we can only accommodate less than half this capacity at the venue...we truly wish we could have everybody there! We didn’t expect so much interest so fast over the holiday weekend. Maybe we will add more events next year! But good news - please save the date for our Fall Full Moon Jazz Sunday, September 27th. Stay tuned for a new registration system too! 🌕✨

Mount Sanitas Trails Need Repair

YOU Can Help!

A historic effort is underway to repair the iconic Mount Sanitas trails and recreation area, improve community access, and restore damaged areas and fragile native plant life with a $1.1 million matching grant. We’re calling on our community to join the legacy and step up for Sanitas with a gift of donation!

https://bosc.org/donate/

For more than a century, Mount Sanitas has been Boulder’s backyard sanctuary - a place to move, breathe, and heal. Its dramatic hogback ridges, Ponderosa Pine forests, and sweeping grasslands draw nearly 375,000 visits to its trails every year, making it one of the most popular recreation areas in Boulder.

Boulder Open Space Conservancy is raising funds to leverage a $1.1 million grant to repair and protect this irreplaceable landscape for future generations. Your tax-deductible gift - whatever feels meaningful to you - will directly increase sustainability and help preserve this beautiful open space that serves as our city’s backdrop for generations to come.

This is our chance to honor the legacy of Mount Sanitas and ensure it endures.

THANK YOU for Stepping Up for Sanitas!

Have you taken our multimodal questionnaire yet?

We're asking you to help guide the future of multimodal access: trails, trailheads, bike connections, wayfinding and more. It's part of a bigger push to make Boulder's open spaces easier to reach for everyone, building on work like the 67 new bike racks we just installed across the system. A week left to share your input. Open through May 3.

Chip Isenhart - of Wild Ranch, supporting livestock producers on the front lines of wolf conflict;

Dave Johnson - supporting Snow Leopard conservation as Director of the Katie Adamson Conservation Fund;

Boulder Open Space Conservancy is excited to announce our partnership with Boulder International Film Festival again this year!

BOSC will co-present a very important film, Snow Leopard Sisters, on Sat, April 11th at 10:00am showing at Grace Commons 1820 15th St. in Boulder.

Snow Leopard Sisters tells the extraordinary story of an unlikely yet unbreakable friendship between two Indigenous women living in one of the most remote corners of the Himalayas. The film follows snow leopard conservationist Tshiring Lhamu Lama as she mentors 17-year-old Tenzin Bhuti Gurung, who is seeking to escape a forced marriage. Together, they traverse the rugged terrain of the Himalayas in search of the endangered snow leopard, discovering courage, resilience, and the power of women’s leadership along the way.

After the film, BOSC is hosting a free panel Q&A and Call 2 Action for folks who were moved during the film to take action for local wildlife. Panelists will be announced soon!

Go to Bosc.org or biff1.com for more info.
