Grasslands provide the feed base for grazing livestock and thus numerous high-quality foods, but such livestock also provides products such as fertilizer, transport, traction, fiber, and leather.
National Grassland Ecosystems provide services that:
- Mitigate drought and floods.
- Cycle and move nutrients.
- Detoxify and decompose waste.
- Control agricultural pests.
- Generate and preserve soils and renew their fertility.
- Contribute to climate stability.
