Treehouse Environmental grew out of years of friendship, fieldwork, and a shared commitment to environmental restoration. Our work is rooted in the belief that restoration, conservation, and climate resilience require both technical skill and long-term care for the places we serve.
We started Treehouse to support people and organizations working to restore, protect, and steward natural landscapes through applied science, field experience, and clear project strategy. Our work is grounded in Hawai‘i and the Pacific Islands, where fragile ecosystems face urgent and complex pressures, and where relationships among people, land, water, and natural resources carry deep cultural and community significance. We are especially interested in working with clients and collaborators who share that commitment to place-based restoration, conservation, and climate resilience.
Through our work, we aim to help clients understand site conditions, plan realistic next steps, document progress, and contribute to the protection and restoration of natural landscapes.
