Table 2 Estimates of the amount of young forest (0–30 years) under past, current and future fire regime and current harvest levels in north-eastern Canada. Values in Bold exceed the past range, values in italics are lower than the past range

From: Young and old forest in the boreal: critical stages of ecosystem dynamics and management under global change

Region Study area Area (km2) Lat (Decimal degrees) Long (Decimal degrees) Reference Fire region (Boulanger et al. 2014) Percentage of young forests (0–30 years)

  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
