Lincoln, Neb. —With a third successful prescribed burn completed at Barta Brothers Ranch on April 21, researchers are seeing what fire can and cannot do about invasive redcedars.

“Burning isn’t a panacea for tree invasion, but it kills younger cedars,” Craig Allen, director of the project, said. “Older trees can escape fires, and have to be removed by other means, and after fire, young cedars can germinate in large numbers, so it usually takes follow-up fires to kill new young trees, until the seed source in the soil is depleted.”
