Abstract: Fire management is an important issue for landholders in mallee areas. Relationships between eucalypt litter fuel loads and fire intensity are well researched, but basic information on fuel re-accumulation after fire is lacking. We compared differences in litter bed size beneath mallee trees with increasing time since fire, and related tree dimensions to litter bed size across a short spectrum (3, 13 and >30 years) of time since fire. As expected, all tree and litter dimensions increased significantly with time since fire with the exception of litter density. Litter density (kg m-3) was significantly greater 13 years after fire than 30 years after fire. This is likely due to changes in litter composition with increasing time since fire. Canopy area was the best predictor of litter bed area (R2=0.73) and volume (R2 = 0.81). Our data confirm that relationships identified between crown size and litter bed size are upheld in recently burnt mallee communities.
