Let's Stop these Silent Invaders
Our water, wildlife, and economy are threatened by invasive species. Travelers from faraway lands without predators here in Oregon, they spread quickly. Native plants and animals are pushed out, and entire ecosystems and agricultural areas can be seriously degraded or destroyed.

Garden Smart Guide
In 2008, SOLVE partnered with the Oregon Invasive Species Council, Oregon Public Broadcasting, The Nature Conservancy, and other community organizations to create more awareness about the problem of invasive plants and animals. One product of this partnership was OPB’s award winning documentary The Silent Invasion. Another was the Garden Smart Oregon guide. This booklet, developed in association with The Nature Conservancy, Portland BES, Oregon Sea Grant and the Oregon Association of Nurseries, highlights the plants that are most likely to cause problems in our yards along with several suggested alternative non-invasive plants that are unlikely to escape into the natural environment. You can download the guide here or request a paper copy by contacting SOLVE at 503-844-9571 or firstname.lastname@example.org.
