To measure the effect on Eucalyptus delegatensis populations of high severity fires in quick succession.
Type of Study:
Observational; pre-existing contrasts.
Single high-severity fires caused >95% adult mortality and triggered mass regeneration, but a second fire in quick succession killed 97% of the regenerating alpine ash.
Unburnt, once-burnt and twice-burnt in the decade prior to sampling.
careful intervention (e.g. targetted prescribed burning, reseeding) required to prevent local extinction.
Response variable :
One belt transect, at each of 10 sites per fire history.
