New model sheds light on grassland desertification dynamics

In a study published in Remote Sensing, scientists from the Aerospace Information Research Institute (AIR) of the Chinese Academy of Sciences (CAS) have employed a Desertification Difference Index (DDI) model to better understand ...

Bud bank confers post-drought recovery across grasslands

Grasslands are important terrestrial ecosystems and provide many ecosystem services. As global climate change has accelerated in recent years, the increased frequency of extreme droughts has negatively affected the aboveground ...

Grasslands are areas where the vegetation is dominated by grasses (Poaceae) and other herbaceous (non-woody) plants (forbs). However, sedge (Cyperaceae) and rush (Juncaceae) families can also be found. Grasslands occur naturally on all continents except Antarctica. In temperate latitudes, such as northwestern Europe and the Great Plains and California in North America, native grasslands are dominated by perennial bunch grass species, whereas in warmer climates annual species form a greater component of the vegetation.

Grasslands are found in most ecoregion of the Earth. For example there are five terrestrial ecoregion classifications (subdivisions) of the temperate grasslands, savannas, and shrublands biome ('ecosystem'), which is one of eight terrestrial ecozones of the Earth's surface.
