Grassland and the Role of Fire Disturbance
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
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.
