Photographs from two transects at Snag Lake (SL) taken 1 year post-fire (1998) and 9 years post-fire (2007), illustrating variability in post-fire aspen regeneration associated with spatial variability in fire intensity. Top: suboptimal, shaded, regeneration conditions associated with low intensity burning that lethally girdled live aspen but did not kill established conifers (note post-fire dead and down aspen stems). Bottom: transect with higher fire intensity that killed most conifers and reduced canopy cover, which is associated with the maximum aspen regeneration numbers and heights among transects within the site.
