Humans have long looked to grasslands and their ability to support large herds of animals as an opportunity. Grassland wildlife in some ecosystems around the world must compete with domestic livestock for food and water.
In some places, livestock are kept in such large densities that overgrazing and soil erosion occurs, degrading the landscape. But when sustainably managed, herds of domestic livestock can help preserve grassland biodiversity and avoid conversion to cropland. Grasslands that have remained largely intact until now, such as East African savannahs, are at risk of being lost to agriculture. The plants and animals that live in a grassland are connected through a vast web of interactions.
Biotic Features In An Open Grassland
But the removal of key species—such as buffalo and prairie dogs in the American West—and introduction of invasive species, like cane toads in northern Australia, have disrupted the balance in these ecosystems and damaged a host of other species. Grasslands are home to some of the most magnificent animals on the planet—elephants, bison, lions—and hunters have found them to be enticing prey. But when hunting is not controlled or is conducted illegally, species can be wiped out. WWF works with local stakeholders to preserve biodiversity and ensure that natural resources are used in a sustainable manner that benefits the local community.
We also work with governments and local communities to conserve and sustainably manage the water and other resources in grassland ecosystems. WWF also advocates for nations to more effectively enforce wildlife laws and has trained local wildlife authorities in modern methods of antipoaching and provided equipment and provisions for antipoaching teams in several nations.
