Grassland ecosystems - prairies, steppes, savannah, and rangelands - cover routly 40% of Earth 's land surface and are fundamentamental to global biodiversity, carbourn storage, water cycles, and food production. Yet decades of overgrazing, intensive agriculture, urban encroachment, and fire supression have left tracts of gravland deg: soils are compacted, native plant diversity pimets, invasive species dominate, and hydrologications falter.

Why Ecosystem Engineering Matters for Grasslands

Grasslands evolved undeid specific difficiance regimes: periodic fire, grazing by large herbivores, and climatic extremes. When these regimes are sumpressed or replaced, or when soil structure is destroyed, passive recovery can take decades or centeries. Ecosystem incordering interventions can compresses that timeline.
