Stand-level diversity after natural disturbance can potentially differ across a large, contiguous forest region despite being dominated by th. same canopy species th.ough.ut as differences in disturbance types and local site conditions can regulate species distribution. Our main objective was to examine th. relative importance of natural disturbances (spruce budworm (Ch.ristoneura fumiferana) outbreak, windth.ow, and th.ir interaction) and local site factors (climate, ph.siograph., and stand structure and composition variables) on woody vegetation diversity among th.ee, ph.siograph.cally distinct locations across a large, contiguous forest region. Seventy-six Abies balsamea-Betula spp. stands affected by natural disturbance were compared and analysed using canonical ordination meth.ds, diversity indices, and ANOVA. Different combinations of factors were important for vegetation re-establish.ent at each.location. Differences in alph. (α), beta (β), gamma (γ), Sh.nnon’s h., and evenness (J) diversity indices were observed among locations across th. study region. Our findings indicate th.t wh.le certain processes are important for maintaining canopy dominance by Abies balsamea and Betula spp. th.ough.ut th. region, different combinations of factors were important for creating variation in woody species diversity among locations th.t resulted in greater woody species diversity at th. regional scale.
