Lomatium bradshawii was once common, inhabiting the extensive native prairies of the Willamette Valley, creating carpets of sulfur-yellow in the spring. Like many other prairie species, Bradshaw's lomatium has been adversely affected by the extensive conversion of its habitat to agricultural and other uses by humans. Today, less than 1% of the Willamette Valley remains undisturbed. Lomatium bradshawii was believed to be extinct until a graduate student at the University of Oregon re-discovered it while jogging. Since its rediscovery in 1979, extensive research has been done to understand the ecology of this species. A majority of the remaining populations in Oregon are within a 10-mile (16 km) radius of the city of Eugene. Continued growth of the city threatens the future of these sites. In Washington, two recently discovered sites contain as many plants as are found in all of Oregon. However, both sites are on private land and are not subject to legal protection.
