Grassland (Prairie, Steppe & Savanna)

Biome dominated by grasses and maintained by fire, grazing, and drought, storing most of its carbon in deep root systems and soil.

Core Principles & Analysis

• Prairie grasses keep most of their biomass underground, with roots reaching depths over 3 meters.
• Periodic fire and grazing suppress woody plants and maintain the open grass canopy.
• Deep grassland soils such as chernozem form some of Earth's most productive farmland.

Specifications & Metrics

• COVERAGE: ~40% of Earth's land surface
