Title: Effects of Stand-Replacing Wildfire on Ecosystem Carbon Balance in Lake States Jack Pine Forests

Project Proposal Abstract: A key barrier to resolving uncertainty about the effects of fire on ecosystem C balance is the fact that fire effects on ecosystem C budgets are manifested over decadal time scales, meaning that we are largely forced to draw inferences using space-for-time substitution, or chronosequence, studies. Whereas chronosequences allow us to study processes occurring over long time scales, they are almost never re-sampled raising questions about the validity of chronosequence estimates of post-fire C dynamics. We are proposing to re-sample a well-studied fire chronosequence of jack pine (Pinus banksiana) forests (Rothstein et al. 2004; Yermakov and Rothstein 2006; Spaulding and Rothstein 2009), which will provide a unique opportunity to both determine the accuracy of chronosequence estimates of post-fire C fluxes for this forest type, as well as elucidate spatial variability in rates of C loss and recovery following wildfire. We also propose to combine re-sampling with re-analysis of archived soil samples and application of new stable-isotope techniques to better understand the response of mineral soil C to stand-replacing wildfire. Finally, we will integrate these results to quantify the consequences of alternative management practices for landscape-scale carbon storage and cycling in jack pine forest which will be delivered to land managers in the form of a General Technical Report and accompanying seminar. This study will make important fundamental contributions to our knowledge of fire effects on ecosystem C balance, as well as providing valuable tools to federal agencies managing jack pine forests in the Lake States.
