State
Grassland biomes have moderate, seasonal precipitation, and periodic fire disturbance limits woody-plant encroachment, maintaining the biome's characteristic open, grass-dominated structure.
Show
Periodic fire kills encroaching tree seedlings before they shade out the grasses, which resprout quickly from fire-protected underground roots.
Watch for
Fire in a fire-adapted biome is a maintaining disturbance, not a destructive anomaly the ecosystem merely survives.
