Effects Of Fire Season And Temperature On A Spotted Knapweed (Centaurea Stoebe) Infested Grassland, Zachery T. Pitman

Masters Theses

Invasive species, including the non-native forb Centaurea stoebe (spotted knapweed), constitute an imminent threat to degraded and restored native prairies. Considering the major threat that C. stoebe poses to imperiled prairie ecosystems, I examined the effectiveness of fire as a control agent of C. stoebe and (±)-catechin. I conducted a 2-year experiment in part of a restored tallgrass prairie community at Pierce Cedar Creek Institute in Barry County, Michigan between May and August of 2016 and 2017. My experiment consisted of individually burning 60 1-m² plots with a propane torch to achieve high (316° C) and low (103° C) temperatures …
