Title: To Burn Or Not To Burn Oriental Bittersweet: A Fire Manager’s Conundrum

Project Proposal Abstract: Oriental bittersweet (Celastrus orbiculatus) is an introduced liana that has invaded much of the Eastern US and is invading west into the Great Plains. In forests, it can girdle and damage canopy trees. At Indiana Dunes, we have discovered that it is invading non-forested habitats as well. Anecdotal evidence suggests that fire might facilitate its spread but the relationship between fire and this aggressive invader is poorly understood. We propose to investigate the effect of fire on the life history stages of Oriental bittersweet to address the following issues: 1) What fire temperatures cause seed mortality? 2) Does fire modify habitat susceptibility to invasion? 3) Both fire and cutting can cause Oriental bittersweet to resprout. Does the resprouting response differ between these two treatments and can a combination of cutting and pre- or post-fire treatment facilitate its removal? 4) How does Oriental bittersweet abundance vary with fire regime and can we predict the abundance of this species in a fire mosaic landscape based on fire return interval and time since last fire? From these studies managers will be better equipped to understand when and if burning should be conducted to reduce Oriental bittersweet invasion and to predict Oriental bittersweet presence and abundance in a pyric landscape.
