Through Sustainable Conservation and the California Horticultural Invasives Prevention (Cal-HIP) committee, the PlantRight campaign was founded in 2005. PlantRight has brought together leaders from the nursery industry, environmental groups, and academics. Its goal is to address the ongoing sale of invasive garden plants in California and to develop a strategy to remove these plants from retail sale, as well as to prevent new potentially invasive plants from being introduced. To accomplish this first objective, PlantRight teamed with the UC Master Gardener program in 2011 to survey over 225 retail nurseries throughout the state for 19 known invasive species originating from the industry.

One way that invasive weed seeds and root fragments can be moved is in hay and straw used for animal feed and bedding or in materials used for erosion control.
Seeds can also be transferred in animal manure if the animal has recently ingested invasive plants in infested feed or while grazing. These seeds and plant parts can then reproduce and colonize a previously uninfested area --- and if left...

Invasive weed seeds and other reproductive parts are often moved to new locations via: imported gravel and fill dirt; vehicles and equipment; or in erosion control materials. Treating weeds over a large area is expensive and often impossible, so land managers can look to weed prevention as a cost-effective...
