This year, NatureBridge made incredible progress in expanding access to environmental education, growing our student reach, and strengthening key partnerships. From opening the National Environmental Science Center (NESC) to welcoming more schools to launching new initiatives, we continue to create transformative outdoor learning experiences that inspire the next generation of environmental stewards. As we reflect on our achievements and look ahead to new opportunities, we invite you to explore our 2024-25 Annual Report and see the impact of your support.
Annual
Report
2024–2025
01 Letter from the CEO and Board Chair
As we reflect on the remarkable year that was 2024-25, we are filled with immense gratitude and pride in the NatureBridge community. From the students who first adventured with us at the newly opened National Environmental Science Center to the dedicated educators, staff, and supporters who make our work possible, this year has been one of growth, connection, and impact.
We loved seeing our work featured in USA Today not once, but twice this year. The September article spotlighted the powerful partnership between NatureBridge and Washington’s Outdoor School for All program, showcasing how we break barriers so that environmental science education is accessible to more students from more communities. Another feature, in December, highlighted NatureBridge’s enduring commitment to experiential learning and its transformative effect on students' understanding of the natural world.
This year provided moments of deep reflection as we said goodbye to beloved members of our NatureBridge family. We honored the lives and legacies of Donald Rees, our founding executive director, who laid the foundation for our mission; Ty Cobb, our former president whose leadership helped us expand our reach; Bill Anders, a founding member of the Yosemite Institute whose iconic Earthrise photo inspired generations of adventurers; Jay Flood, a former board chair who championed our mission with passion; our dear friend and advocate Bruce Bailey; and Annie Schuler, whose work helped unify NatureBridge as our Director of Communications. Their contributions live on in the vibrant community they helped build.
Your unwavering support made this year’s milestones possible, from welcoming thousands of students to our campuses to expanding partnerships that ensure our programs reach those who need them most. Because of your investment in NatureBridge, students are not just learning about the environment—they are learning in the environment, cultivating a lifelong connection to the natural world and the skills to protect it.
We hope you take a moment to read this year’s Annual Report and see the impact you have made. Together, we are inspiring the next generation of environmental leaders and ensuring that the beauty and wonder of the outdoors remain accessible to all.
Thank you for standing with us, for believing in our mission, and for continuing to invest in the future of our planet. Here’s to another year of growth, learning, and stewardship!
02Looking Back, Moving Forward


The NESC Opens to Students
On a chilly autumn afternoon in late October, NatureBridge's National Environmental Science Center (NESC) in Yosemite National Park opened its doors to its very first school groups, marking a pivotal moment for NatureBridge. This state-of-the-art facility has been nearly 15 years in the making, and we are thrilled to announce that students are now officially on campus, laughing, learning, and engaging with all of the opportunities for immersive learning at the NESC.
“This experience completely changed my way of seeing life and nature… thank you, forest, thank you, nature for showing us to be here and learn and connect with you.”
— Arlette, NatureBridge Olympic student
We are excited to celebrate staff who continue to believe in our mission and provide transformative experiences for our students, with some working with us for as many as 25+ years.

As part of our recent Cognia accreditation in April 2024, we have been further refining our science capacity and the academic rigor of our programs.
We have been engaging more broadly with the outdoor education field through professional development, conferences, and partners like the California Environmental Literacy Initiative (CAELI) so we can remain a thought-leader and model for outdoor schools around the country. We are also in the initial stages of engagement with National Science Foundation-funded environmental education outcomes evaluation efforts in Washington and California, and along with our survey of over 2,100 students, these will help NatureBridge continue to enhance our programs through thoughtful assessment and feedback.

03Our Students in 2024
Fulfilling our mission of connecting as many young people as possible with the wonder and science of nature remains at the center of our work. In 2024-2025, we welcomed 28,500+ students for a total of 99,000+ participation days across our four campuses.

Each year, NatureBridge welcomes students from across the country.
Each year, NatureBridge welcomes students from across the country. This year was no different, and we welcomed students from 15+ states including California, New York, Texas, Wisconsin, and more. Though our students come from different places, their joy and excitement to participate in these transformative outdoor experiences connects them all.

We have been piloting a secure online platform for teachers to engage with all aspects of planning and effectively manage their NatureBridge program through key enhancements in our use of Salesforce. This will improve operational efficiency, better-equipping staff to prepare for programs and allowing us to dedicate more time to ensuring students have a transformative experience in the outdoors.
Every year, NatureBridge provides scholarship assistance to schools and students who face barriers to experiencing our incredible outdoor classrooms in order to fulfill our mission to connect every young person to the wonder and science of nature. Learn more about our Scholarship Fund.

7Event Sponsors and Partners
NatureBridge events raise over a million dollars in revenue for the organization every year! These donations fund scholarships, campus improvement projects, staff training, and so much more. NatureBridge events are also fun: students share stories, field and subject experts bring their unique perspective to the importance of our mission, and educators bring programs to life for attendees, all while raising critical funds.

“Why do we support NatureBridge? Delaware North takes pride in operating in national parks throughout the U.S., and we strive to be good stewards while also inspiring the next generation of conservationists and explorers. NatureBridge is a great partner because it connects children and adolescents from different backgrounds and geographies to our parks through immersive experiences. All of America’s children should grow up knowing what is in their backyard, and that it is theirs to enjoy. We’re proud to support the mission and great work of NatureBridge.”
