Our Story & Our Partners

In 2006, in an ivy-riddled area of Portland’s Southwest Hills, a group called the West Willamette Restoration Partnership launched a pilot program to achieve (what seemed) a modest goal: to help 25 homeowners remove noxious weeds and restore the native habitat to their yards. The Backyard Program, as it was called, was one sliver of a much bigger effort by many, many partners to restore a 35,000-acre forested corridor that was one of this region’s most important remaining wildlife habitat. Coyote, deer, birds and beneficial insects all lived in the area, but its health was seriously threatened by invasive weeds.

The Backyard Habitat program, then as now, recognized that homeowners, whose yards adjoined—or even were a part of—this natural area had to be part of the effort to keep the native habitat healthy and thriving. In a developed area, people had to be part of the solution.

It wasn’t clear that the Backyard Habitat pilot would even work. After all, it asked participating homeowners to remove all invasive weeds and replant with native plants. Its marketing consisted of yard signs and word-of-mouth. Would they even be interested?

They weren’t just interested, they became enthusiasts. The more weeds they removed, the more native plants had space to grow. The more birds showed up to forage. Word spread. Other wanted to join from throughout the region.

In 2009, Columbia Land Trust and the Audubon Society of Portland joined forced to launch the program Portland-wide. Nearly seven years later, the program now has over 3,200 participants, over 20 partners and funders, and has developed deep roots in communities throughout Portland, Lake Oswego, Gresham, and Fairview.

Why the Program Matters

According to our regional government estimates, the population of the Portland-Vancouver Metro area is expected to double by 2050. Development will follow, a fact that has real consequences for the natural world, our animals and our native plant communities. Over the past decades, we have witnessed loss of native species on the landscape, countless new invasive weed infestations, alarming declines in native pollinator populations, increased urban hazards to the 209 species of migratory birds that live or fly through this region, and radically altered streams—the lifelines of many natural areas.

To date, regional protection and restoration efforts have focused most heavily on public lands, public right of way, and regulating new development. However, residential landscapes make up about 40 percent of the Portland metropolitan area. Therefore, they have a significant role to play in developing healthy habitats for people and wildlife.   People’s good gardening and maintenance efforts on their own land can prevent future introductions and the spread of invasive species and provide safe passage for wildlife, and reduce contaminated runoff into our waterways.
