Title
Fuels or microclimate? Understanding the drivers of fire feedbacks at savanna–forest boundaries
WILLIAM A. HOFFMANN; SUSAN Y. JACONIS; KRISTEN L. MCKINLEY; et al. Austral Ecology 2011. doi:10.1111/j.1442-9993.2011.02324.x
Other claims from this paper (8)
- Observation Most variables showed strong gradients across savanna–forest boundaries, except total fuel load.
- Observation Savannas had higher daytime wind speed and air temperature than forests.
- Observation Savannas had lower daytime relative humidity and fuel moisture than forests.
- Observation Fuel loads were similar in savanna and forest.
- Observation The model predicted faster savanna fires than forest fires.
- Observation The model predicted more intense savanna fires than forest fires.
- Observation The model predicted greater flame lengths for savanna fires than forest fires.
- Mechanism Sensitivity analysis attributed most fire behavior differences to low bulk density of grassy fuels, with smaller contributions from wind, moisture and fuel load.
