The newly-obvious threat of artichoke thistle in the burn area "shocked people into action," Tidwell commented, and a coalition was formed to address the problem.
The wildfire made artichoke thistle vulnerable to the coalition.
Tidwell estimates that 2,500 to 3,000 acres of artichoke thistle were sprayed throughout the 17,000-acre burn area.
Wherever we look at undisturbed chaparral, coastal sage brush or grasslands, the artichoke thistle can't get in," Pryor said.
A one percent cover of artichoke thistle is expected in succeeding years, and spot spraying will be used to control it.
