Distribution of rangeland types globally

Rangelands are diverse in their vegetation driven by highly fluctuating rainfall, temperature and other climate phenomena, and influenced by soils and management practices. Rangelands have many economic, ecological, social, and cultural values, and a wealth of biodiversity that supports ecosystem health. 

This map has been produced using seven of fourteen biomes or rangeland types made up of terrestrial ecoregions as defined by WWF. For more information on these terrestrial ecoregions see: https://www.worldwildlife.org/publications/terrestrial-ecoregions-of-the-world

Key Figures

1. Rangelands cover 54% of global terrestrial surface (148,326,000 km2) to a total of 79,509,421 km2.

2. The largest rangeland biome is deserts and xeric shrublands covering 27,984,645 km2 or 19% of global terrestrial surface.

3. Rangelands are made up of seven biomes or rangeland types namely: 35% deserts and xeric shrublands, 1% flooded grasslands and savannas, 4% mediterranean forests, woodlands and scrub, 6% montane grasslands and shrublands, 13% temperate grasslands, savannas and shrublands, 26% tropical and subtropical grasslands, savannas and shrublands, and 15% tundra.
