Who We Are

SOLVE is an environmental non-profit, evolving from a grassroots initiative into a national model for volunteer environmental stewardship.

Today, SOLVE mobilizes and trains thousands of volunteers across Oregon and Southwest Washington. Volunteers engage in cleaning and restoring neighborhoods and natural areas, fostering a legacy of environmental care and community involvement.

Our Mission

SOLVE's mission is to bring Oregonians together to improve our environment and build a legacy of stewardship.

Our Roots

S.O.L.V. (Stop Oregon Litter and Vandalism) started as an all-volunteer-driven organization to address litter and vandalism throughout the state. We were founded in 1969 by a charge from eco-pioneering Governor Tom McCall, who believed it was every Oregon citizen's inherent right to enjoy and take responsibility for the places where we live, work, and play.

Commitment to Diversity 

Just as biodiversity is crucial for a healthy environment, human diversity is essential for a thriving society. SOLVE is dedicated to creating an inclusive space for people of all backgrounds to engage in environmental volunteerism. Our mission is for all Oregonians, regardless of age, gender, race, religion, or socio-economic background, to unite in improving our environment. We aim to address disparities in environmental impact and ensure safety for all residents.

Land Acknowledgement

The indigenous tribes and bands have been an integral part of the Oregon and Northwest regions since time immemorial and remain a vibrant presence in Oregon today. We want to express our deep respect for the First Peoples of this land, specifically the nine federally recognized tribes of Oregon: the Burns Paiute Tribe, Confederated Tribes of Coos, Lower Umpqua & Siuslaw Indians, Confederated Tribes of Grand Ronde, Confederated Tribes of Siletz Indians, Confederated Tribes of the Umatilla Indian Reservation, Confederated Tribes of the Warm Springs Reservation, Coquille Indian Tribe, Cow Creek Band of the Umpqua Tribe of Indians, and The Klamath Tribes. It's of utmost importance to acknowledge and honor the enduring legal and spiritual connection between the land, its flora and fauna, and the indigenous peoples who have lived in what we now call Oregon. The profound interconnectedness between the people, the land, and the natural environment cannot be overstated; the well-being of one is essential for the well-being of all. We recognize the pre-existing and continuing sovereignty of the nine federally recognized tribes with deep roots in this region and express our gratitude for their ongoing sharing of traditional ecological knowledge and their perspective on how we can mutually care for one another and the land, allowing it to care for us in return. We are committed to entering into a respectful and productive partnership as stewards of these lands.

Our Impact

Annually, SOLVE recruits, organizes, and guides volunteers through thousands of environmental projects and litter cleanup events to address a broader range of threats to Oregon's health, livability, and economic viability. Across the state, we unite diverse communities to improve the health and safety of our neighborhoods and natural areas, including our coast, rivers, parks, and forests.
