Prescribed burns are increasingly used by land managers to clear areas dominated by non-native species, but like many management actions they can have quite variable outcomes. The efficacy of a burn may be contingent on the dominant species or seasonality of the burn. Moreover, the efficacy may be contingent on dynamics post treatment. Here we share results from two studies about the effects of prescribed burns on 1) the subsequent establishment of invasive species and 2) the recovery dynamics of the soil microbial community. Our findings support previous work suggesting the completeness and intensity of a fire affect post-management dynamics.
