WHAT THE EVIDENCE SAYS
Prescribed fire increased bare ground and tree girdling created snags and structural change, but desired groundlayer recruitment remained limited where shrub cover and residual canopy continued to constrain light and establishment. The authors argue for more targeted canopy reduction, refined burning and active seed inputs where propagule limitation persists.
WHY IT MATTERS / OUR READ
Restoring a process is not always enough to restore the community that once depended on it. Fire can be necessary and still insufficient when canopy structure, shrubs and missing propagules keep the system on a different trajectory.
CAVEATS / UNCERTAINTY
The experiment covers two degraded savanna communities and a finite treatment period, so responses may differ under other soils, seed banks and disturbance histories. Additional treatments recommended by the authors are management inferences rather than outcomes already demonstrated in this study.
