RT Journal Article SR Electronic T1 Post-fire vegetation communities in western Colorado JF Native Plants Journal JO NATIVE PLANTS JOURNAL FD University of Wisconsin Press SP 226 OP 237 DO 10.3368/npj.20.3.226 VO 20 IS 3 A1 M Nikki Grant-Hoffman A1 James Dollerschell YR 2019 UL http://npj.uwpress.org/content/20/3/226.abstract AB Wildfire is a cause of disturbance on public lands, and post-fire treatments often include broadcast seeding of native and non-native seeds. We collected vegetation data from an area burned by a wildfire in western Colorado in 2012 and, where available, compared pre- and post-fire data. We sought to determine how dominant plant species responded to fire and to determine post-fire vegetation community dynamics as compared to a typical response as described in the floristic composition model. Seed mixes were chosen based on previously available vegetation and treatment data. We found that areas seeded with a native seed mix had increasing cover of native forbs, whereas areas seeded with a non-native mix did not. However, the cause of low forbs in areas seeded with non-natives is not clear. We also found several native plant species that recovered after the fire, while sagebrush was absent after fire. Surprisingly, cheatgrass (Bromus tectorum L. [Poaceae]) frequency did not increase after fire in areas where pre- and post-fire data were available.
