Project Details
Native to New Zealand, biddy-biddy likely spread to the United States in the wool of imported sheep. Plants thrive in well drained soils and compete with native plants on coastal bluffs and in lawns where they form dense mats. Coastal habitats with summer moisture and infrequent frosts are particularly vulnerable, especially those in areas with heavy usage and foot traffic, as the seed burrs easily attach to boots, pants, gloves, pet fur, equipment, car tires, etc. and are often spread by visitors from one location to another.
To date on the south coast, biddy-biddy is only known to occur in limited distribution along the coastline in Coos and Curry counties. Noxious weeds partners have dramatically reduced a population at Cape Blanco State Park and are also treating infested lawns at the USFS Ranger Station in Gold Beach.
