Dry and Wet season burns
The dry season begins when precipitation declines

Croton post-fire recovery linked to hydrology
More absences and deaths after wet-season fire
WET SEASON VS. DRY SEASON BURNING AFFECTSSURVIVAL
CROTON LINEARIS RESPROUTS IMMEDIATELY FOLLOWING FIRE, AND SURVIVAL DECLINES OVER TIME
HYDROLOGY CAN BE MANAGED
Preliminary conclusions: Inundation following fire reduces survival
