It was our objective to determine whether plant-soil feedbacks confer weed suppression to a shrub-steppe ecosystem in Washington State. We found that soils developed by native bluebunch wheatgrass communities reduced knapweed growth from 18 to 5% ground cover. A pairwise feedback model developed from our data successfully predicted the native and weedy plant distribution seen on the landscape. We suggest that endemic soil-based mechanisms of weed control may be common and will produce novel techniques for the management of invasive plants.
