Projects
The HST | Foundation supports pioneering initiatives at the intersection of art, ecology, community practice, and emerging technology.
Each project explores a different facet of our mission: to deepen human connection with the living world, to translate ecological intelligence into cultural experience, and to accelerate new forms of environmental stewardship.
From large-scale international art journeys to hyperlocal citizen-science experiments, our projects share a common thread: they listen to the signals of nature and transform them into stories, knowledge, and collective action.
And finally - the projects we support will all inform the world's first widely accessible Ecological AI.
TREELINE is a creative musical project connecting communities to their environments, trees and forests.
Acclaimed British Composer Graham Fitkin works with communities throughout Europe and the UK following old growth forests and their remnants in 10 countries from Romania to the UK, using music, data collection, field recordings and concert performances to engender greater respect for trees and biodiversity, and increase understanding of why these things are so important.
The HST Foundation is proud to support Graham Fitkin in adding layers of engagement and ecological data to the trees in the Treeline project.

Keepers is a gamified civic initiative designed to solve a simple but persistent problem:
When it comes to the ecosystem services provided by trees, most people find data and dashboards dull. Statistics alone don’t create emotional investment. And without emotional investment, we consistently undervalue the real, living services that trees provide to our cities.
Keepers flips that dynamic.
Instead of asking people to care about abstract metrics, we transform ecosystem services into tangible, measurable, gamified — and emotionally understood — assets.
Citizens choose and activate trees in their city, building personal collections of ecosystem-service-producing living infrastructure. The trees they care for immediately begin calculating and reporting the environmental benefits they provide in the real world: carbon sequestration, urban cooling, air pollution removal, biodiversity value, and climate resilience.
These living metrics are streamed in real time to a local Highly Sensitive Tree — a shared urban reference point that learns from the collective activity of its city’s Treekeepers.
And here’s the secret sauce:
As trees generate real ecosystem services, participants earn digital credits — HST Rings — which can be redeemed for real-world perks or reinvested to activate and care for even more trees.
Keepers sits at the intersection of ecological stewardship, civic connection, and strategic play — a city-scale game where the board is alive, the assets breathe, and everyone benefits when the system thrives.
