Burning Effects on the Development of a Restored Native Plant Community

Establishment of native plant communities on degraded sites often requires control of invasive species such as spotted knapweed (Centaurea stoebe L.), but the persistence of knapweed in restored plant communities is uncertain. Since 2009, we have studied the effects of various treatments, including burning, on native plant community development on a knapweed-infested site in western Michigan. Prescribed burns were conducted in spring 2012, 2014, and 2015, with fire intensities varying with timing, weather, and grass cover. Presentation by Neil W. MacDonald by Grand Valley State University.
