Establishment of non-native plant species after wildfires: effects of fuel treatments, abiotic and biotic factors, and post-fire grass seeding treatments

Molly E. Hunter, Philip N. Omi, Erik J. Martinson, Geneva W. Chong
Summary - what did the authors do and why?

The authors examined the effects of pre- and post-fire management strategies on the establishment of non-native plant species after high severity wildfire. They further considered other biotic and abiotic factors that may also influence non-native species establishment post-fire.
Publication findings:

Fuel treatments prior to fire did not significantly influence the establishment of non-native species post-fire nor increase the potential for invasion. High severity fire, however, was a strong predictor of non-native species establishment, and invasion was more likely with increasing fire severity, indicated by depth of char in this study.

How does fire severity relate to species composition, non-natives, and structure?
