Aim: 
To measure the effect on Eucalyptus delegatensis populations of high severity fires in quick succession.
Type of Study: 
Observational; pre-existing contrasts.
Key Results: 
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.
Treatments: 
Unburnt, once-burnt and twice-burnt in the decade prior to sampling.
Response: 
careful intervention (e.g. targetted prescribed burning, reseeding) required to prevent local extinction.
Locations: 
Australian Alps.
Response variable : 
Tree diameter.
Replication: 
One belt transect, at each of 10 sites per fire history.
Ecosystem: 
Temperate forest.
