Question

Quizplus · Accepted Answer

Rangelands typically have native grasses with fibrous root systems that are adapted to drought conditions. They are able to survive and recover from periods of drought or other environmental stresses. Overgrazing, on the other hand, can degrade rangeland ecosystems by reducing plant diversity and damaging soil structure. Rangelands are found in a variety of climates, including both temperate and tropical regions. While rangelands can be used for grazing livestock, they also provide other ecosystem services such as carbon storage, water filtration, and biodiversity conservation. Around 30% of the Earth's land surface is classified as rangelands, and they are inhabited by over a billion people whose livelihoods depend on them.
