They have come together in an informal alliance to develop common positions, and identify the grasslands of highest ecological importance for protection or sustainable management under the 30 x 30 commitment. They also continue to monitor their status and threats they face while calling for action from all stakeholders. The Alliance is convened by Dragonfly Advisory. 2.

These undervalued and overlooked landscapes are fundamental to planetary and human health. Protecting them is not merely an urgent mandate; it is central to numerous global challenges. Realizing the hidden value of grasslands provides an opportunity to bolster environmental stability and human development in the crucial decades ahead. Across the globe, grasslands take on different forms, each with unique human and wildlife communities. The Eurasian Steppe, home to nomadic pastoralists, supports wildlife such as the critically endangered Saiga antelope. In Africa's savannahs, indigenous communities coexist with iconic species like lions and elephants. North America's Great Plains, once grazed by vast bison herds, has long sustained Native Americans and more recently ranching communities. South America's Pampas, known for its vast plains, is crucial for bird species like the rhea. Each ecoregion demonstrates an intricate balance between the people and wildlife relying on them.

They also make substantial contributions to freshwater regulation, soil preservation, and other ecosystem services essential for the proper functioning of the planet. Despite their importance, these ecosystems are under threat. Half of the world's grasslands have already suffered some degree of degradation, and the risks are on the rise. The main challenges include agricultural conversion, such as monocropping practices, intensified livestock grazing and the replacement of native grass species with non-native counterpa
