We did it!  We planted our 1,000th tree in less than 2 years!


Our mission is to engage the community to plant and steward native trees and shrubs to improve the environmental health of the Petaluma watershed, shelter wildlife, enrich our lives, save the planet.

ReLeaf rolls out a new program: ReOaking Petaluma’s open spaces

We are beginning a pilot program along the East Side Connector Trail to plant and nurture acorns and seedings along a 4 mile, 68 acre open space landscape owned by the City of Petaluma.  Together with our funder and our partners, we will be restoring these spaces to the oak savannah they originally evolved to be. We will also add shade along this favorite trail.  Please enjoy our East Side Connector Trail slide deck, recently presented at a community input meeting, that explains this new project.

Heat Island Reduction

ReLeaf is prioritizing sites in Petaluma having poor canopy coverage in historically disadvantaged neighborhoods. Trees will cool these neighborhoods, mitigate stormwater flooding, improve public health, and add beauty.

Biodiversity for Life

Trees are key species for the web of life. Our Petaluma native trees provide both habitat and food source for birds and insects.

Carbon Sequestration

Native trees and grasses are the best plants to store carbon above and below ground. Tree roots are in the top few feet and spread out as much as three times the dripline. Living roots can store half of the carbon of plants. Roots exude large volumes of carbon to the soil feeding the soil biota which in turn regenerates the soil, and then stores more carbon. Native bunch grasses are long lived and help restore the soil so carbon accumulates continously for many years.

Never doubt that a small group of thoughtful, committed citizens can change the world; indeed, it's the only thing that ever has.”
