During this time of change, like all species, we are adapting. Our staff is resilient. Our morale is high. The work to protect our natural world is ongoing because you can’t “cancel nature.” The human race cannot stay cooped up indoors forever - but we can use this moment to rethink our relationship to nature. We can ponder what it truly means to share the planet. We can resolve to change the way we live. There is no “social distance” required between humans and the natural world. It is the one place we don’t have to hold our breath.

Page 6 – ACES Annual Report 2020

Chickens provide another essential service at the ranch. Our laying hens follow the ruminants in this rotation; chickens’ natural inclination to scratch the ground while looking for bugs, larvae, and seeds distributes manure left by our ruminants, while also providing them mini–protein meals. Not only does this help to fertilize the pasture, but also cleans and sanitizes the area. While delicious, we consider our farm–fresh eggs – a $30k annual income–generating byproduct – secondary to chickens’ valuable ecosystem services. When raised in a regenerative manner, both livestock and vegetables have the potential to actually reverse carbon emissions by sequestering carbon from the atmosphere into the soil. Regenerative vegetable practices include reduced or no tillage, diverse cover crops, in–farm fertility, no pesticides or synthetic

fertilizers, and multiple crop rotations. In 2019, we made a drastic overhaul to our vegetable production system by switching to a reduced and no–till system. By narrowing aisles and decreasing bed size, our cultivated area shrunk by 20%, yet yields increased compared to 2018. The secret to carbon sequestration is perennial polycultures focused around grass. A side benefit to managing with regenerative “tools” is that they can provide meat, milk, and fiber as byproducts of their work – something tractors and hay baling equipment cannot do. When we’re able to harness the science behind the natural systems of regenerative agriculture, my fears for my two daughters’ futures subside and my hope grows. With any luck, their food over the next century will not deplete the soil, pollute rivers, or heat up our planet. And I will sleep better. Sometimes past 5 am.

ACES environmental education programs get kids outside for 28,000 hours annually. Not only does this provide a unique outdoor “classroom” for learning, but also has been linked to healthy physical and emotional development.

The Roaring Fork Valley offers abundant opportunities for kids to get outdoors and away from screens – and ACES is no exception. Our summer and school–year educational programs are rooted in science but driven by broader principles: promoting fun in the outdoors, letting curiosity drive learning, and shaping the next generation of environmental stewards. “By knowing what’s around you, you have more of a connection to it

School–year programs, which are more standards–based, focus on experiential learning of earth and life sciences.

partnerships. Every student at our three partner schools – Aspen Elementary, Basalt Elementary and Crystal River Elementary – visits their ACES Ed classroom weekly and receives seasonal field science programs. ACES Ed also provides weekly in–classroom environmental science programs in western Garfield County, now in its second year, as part of Garfield County Outdoors, a grant–funded initiative made possible by Great Outdoors Colorado. ACES recently completed construction on the Children’s Garden at Rock Bottom Ranch and developed new curricula to further integrate agriculture education into our in–classroom and field programs. ACES is currently revising our curriculum to align with the Next Generation Science Standards and the 2020 Colorado Academic Standards in science, providing crucial science instruction to students and aiding schools in implementing these standards. By offering standards–aligned in–classroom instruction paired with field experiences, we believe that the unique structure of ACES Ed can serve as a model for environmental education throughout the state and nation. For Roaring Fork Valley high school students, ACES also leads Tomorrow’s Voices each semester: a college–level course with a focus on social justice and environmental stewardship. Encouraged to listen to each other, speak their minds, and consider their broader civic roles, Tomorrow’s Voices students develop critical thinking skills and the agency to effect positive change. ACES’ community programs combine environmental science education with outdoor exploration, transforming the local environment into a community classroom. Community programs provide engaging opportunities for participants ranging from pre–K through adults. Participants form lasting friendships as they share immersive and informative experiences in nature, while developing a sense of place, curiosity about their surroundings, and passion for lifelong learning.

Was this going to be something like Leopold’s Shack, Thoreau’s Walden Pond cabin, or the Murie Ranch? New to town, I wasn’t sure. But the moment I arrived at the Catto Center at Toklat I knew I had made the right choice. The beauty. The history. The plea to help protect the place.

My first few weeks at Toklat were spent learning how to get warm water in the shower (derived from the magic of the pilot-lighted stoves), listening to Trevor’s stories of the place, and somehow answering the ooohs and ahhs from guests who walked in the door.

The Catto Center at Toklat The Catto Center at Toklat, an iconic wilderness retreat center, embodies ACES’ environmental ethic and spirit of stewardship. Since the late 1940s, the Catto Center at Toklat has been a place of quiet refuge where visitors can engage in thoughtful inquiry and reconnect to the natural world. Originally built by the Mace family, the Catto Center at Toklat continues to act as a gathering place for community members and visitors alike, offering a space where people can come together to reflect, rejuvenate, and feel inspired by the local environment. Visitors find their way to the Catto Center at Toklat for a variety of reasons, whether as part of a professional retreat, workshop, community potluck, field science class, to visit with one of our seasonal artists in residence, or simply to take in the stunning natural beauty of the Castle Creek Valley. But no matter how or why they arrive, visitors leave this special place with a renewed sense of connectedness to the land and appreciation for the value of environmental stewardship.

Events Our events do more than bring our community together; they are a celebration of those who take action and effect positive change in the world.

Wild & Scenic Film Festival This annual film festival fundraiser showcases inspiring films in support of ACES’ Tomorrow’s Voices program while celebrating environmental filmmakers, pioneers, and activists.

Fall Colors Potluck Each September, ACES’ annual membership potluck at the Catto Center at Toklat invites guests to experience the peak of fall colors in the Castle Creek Valley.

Stars Above Aspen Last year, ACES partnered with Aspen Skiing Company to host a celebration of astronomy for over 1,000 guests on the top of Aspen Mountain.

Raptor Fair Last July, this educational community event featured personal interactions with over a dozen raptors, including a Bald Eagle, Great Horned Owl, Red–tailed Hawk, and Snowy Owl for over 400 guests.

Farm to Table Dinners During last summer’s growing season, ACES celebrated regenerative agriculture at Rock Bottom Ranch with a series of elegant, locally–sourced meals.

Harvest Party Last October, ACES welcomed 1,400 guests to Rock Bottom Ranch to honor the harvest season with pumpkin–carving, apple– pressing, live music, a pie baking contest and more.

Earth Day ACES celebrates Earth Day every day, but especially on April 22nd by bringing the community together and inspiring action to protect our Earth that sustains us all.

50th Anniversary Events Last year, as we celebrated ACES’ 50th Anniversary, we partnered with other landmark Aspen nonprofits to celebrate mind, body, spirit – and the natural world.

Paul Hawken Public Lecture ACES and the Aspen Institute partnered to bring environmentalist, entrepreneur, and author Paul Hawken to discuss Project Drawdown – a list of comprehensive solutions to climate change – to a sold–out audience at Paepcke Auditorium.

Music Inspired by Nature ACES and Aspen Music Festival and School partnered to bring our community “Music Inspired by Nature,” featuring Stravinsky’s The Rite of Spring as well as pieces from Rachmaninoff and Anna Thorvaldsdottir.

Art for ACES The Aspen Chapel and ACES both celebrated our 50th anniversaries in 2019. In honor of this milestone, the Aspen Chapel Art Gallery sponsored a special show with ten local artists who created works inspired by the beauty of the natural world.

Speaker Series ACES Speaker Series feature scientists, adventurers, and other experts – giving them a platform to share their passions while inspiring, informing, and empowering attendees. Many of our lectures are available to stream at Naturalist Nights This year, scientists shared engaging presentations about local ecology, natural history, environmental issues, and more, including topics like “Too Hot To Trot: Pika Ecology in a Time of Global Change” and “Border Wall Impacts on Wildlife, Wilderness, and Communities: A View from Both Sides.”

Potbelly Perspectives This year, we heard stories of endurance, community building, and wild experiences from local adventurers, including Jordan Curet’s “Discovering the Yukon Wilderness by Paddleboard” and Nika Meyers’ story of “Setting the Unsupported Female Fastest Known Time on Vermont’s Long Trail.”

Jessica Catto Dialogues This year, ACES hosted Reverend Lennox Yearwood Jr. from the Hip Hop Caucus and Shyla Raghav from Conservation International for thought–provoking and engaging free public lectures. These two leaders inspired us to view environmental justice and climate solutions through new lenses, while providing ideas for ways to take action. Wild Perspectives ACES’ inaugural year of Wild Perspectives in Snowmass provided an opportunity for the community to gather and listen to experts share stories on everything from the history of skiing in Snowmass, to forest health, to birding, to activism.

50th Anniversary Capital Campaign Last year, in honor of ACES’ 50th anniversary, the Board of Trustees and ACES’ CEO Chris Lane launched a $12.5 million capital campaign. Today, over 80% of the goal has been reached thanks to inspired leadership giving during the “quiet phase.” The community phase will unfold over the next year to ensure that ACES’ facilities are safe and up-to-date, that vital educational programs reach as many people as possible, and that our beloved sites are protected for the enjoyment of all. As we look to the future, we recognize that our work has just begun. Through an in-depth analysis of what we want to accomplish in the next 50 years, ACES’ staff and board have identified three priority areas of focus:

Community Building Connecting People to Nature at the Catto Center at Toklat Helping influencers of all ages understand humanity’s unique connection to the natural world and its life–supporting and economy– sustaining systems is one of the most direct ways to protect the global environment. ACES’ wilderness retreat center, the Catto Center at Toklat is where we will provide that connection. Surrounded by wilderness and disconnected from a wired world, a renovated Toklat will feature a restored ecology center, artist– and scientist–in–residence programs, natural and historic heritage library, and a wilderness convening space for citizens, children, community and business leaders, policy–makers, teachers, and nonprofits.

Education Building the Environmental Science Education Movement As a beacon of science–based environmental leadership and education for all ages, our place–based science education will cultivate

Protection and Restoration Leading Collaborative Efforts in Ecosystem Restoration and Land Conservation Through our Climate & Forest Department, ACES will restore natural habitats and ecosystems throughout the region, including ACES sites. We will serve as a model for restoration efforts, ecological health, climate education, and outdoor community classrooms, providing cutting–edge, science–based information to the public. This will include assessing the state of our forests and ecosystem health through on–the– ground restoration work, in–depth science analysis, data sharing, and collaborations with universities, government agencies, and other NGOs.

When ACES moves forward with our campaign, we hope you will join us to “Protect the Future”. More details on these initiatives can be found at

community consciousness and environmental stewardship on a local, state, and national level, advancing our mission beyond our physical boundaries and into underserved communities and schools. We will contribute to a national agenda for increased environmental science education. In an effort to teach the world to rethink farming and food, we are transforming Rock Bottom Ranch into a national center modeling regenerative food systems. ACES will create food–literate citizens by: investing in infrastructure to demonstrate scalable, replicable systems of regenerative agriculture, creating a national farmer training program, and teaching these systems to both adults and students.

Hensley & James Peterson

Alex Hager

“We believe ACES is making a profound and vital contribution to our community through creating environmental education, stewardship, and awareness of our natural world for the future of our planet.”

“I’m a firm believer in the power of storytelling as a tool to learn about the world and bring people together. I first got involved with ACES by attending and volunteering at Potbelly Perspectives. It’s one of my favorite winter rituals – getting in a room with a bunch of like–minded folks who share a passion for the natural world and hearing stories from people who have gone on extraordinary journeys.”

James and Hensley Peterson’s long history with ACES is something to celebrate. James joined the ACES Board of Trustees in 1994 and served as Board Chair for five years of his seven–year term. During this time, he was motivated to address ACES’ need for staff housing and began a successful capital campaign to raise funds for housing, including the Treehouse and Straw Bale structures at Hallam Lake and

During her time on the ACES board, Rock Bottom Ranch was conserved with Aspen Valley Land Trust and the Field Study Center was established. During this time, ACES also acquired a wilderness lodge which would become the Catto Center at Toklat. After retiring from the Board of Trustees, Hensley continued to be an advisor on the Toklat Council. James and Hensley are still actively involved as Donor Circles members.
