  1. Past fire = % based on dendro-chronological estimates (Gauthier et al. 2009c) over the last 200–300 years; Current harvest: based on Guindon et al. (2014) between 2001 and 2010; Current fire + harvest = combined of current harvest rate and current annual area burned (from Boulanger et al. 2014); Sustained: based on the average time to reach 100 cubic metres as estimated by Gauthier et al. (2015b); future rates are based on Boulanger et al. (2014) for fire projections, and with the current harvesting rate
