    Grassland - Wikipedia

    • A grassland is an area where the vegetation is dominated by grasses (Poaceae). However, sedge (Cyperaceae) and rush (Juncaceae) can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. Furthermore, gras… See more

    Definitions

    Included among the variety of definitions for grasslands are:
    • "...any plant community, including harvested forages, in which grasses and/or legumes make up the dominant vegetation." … See more

    Ecology

    Grasslands dominated by unsown wild-plant communities ("unimproved grasslands") can be called either natural or "semi-natural" habitat. Although their plant communities are natural, their maintenance depends u… See more

  1. Desert grassland is a transitional grass-dominated landscape community, often positioned between desert shrubland below and the chaparral vegetation type above. The climate of the desert grasslands is generally characterized by warm to hot summers, and by mild and open winters (Martin 1973).

    Arid and semi-arid lands are regions of the world that have harsh environmental conditions, including high temperatures, high evapotranspiration rates, low precipitation rates, and scarcity of freshwater resources.

    Dormant periods when grass growth is absent is a common feature of arid and semi-arid grasslands, when lack of rain and/or low temperatures, inhibit growth. The onset of spring rains and increased temperatures are associated with increased grass growth resulting in increased LAI, light interception and NPP.

    What types of grasslands are in aridity?
    The gradient in aridity includes the three major types of grasslands in northern China (meadow steppe, typical steppe, and desert steppe from wetter to drier)—the largest natural grasslands remaining on Earth.

    Are arid grasslands a thornscrub?
    Arid and semi-arid grasslands comprise most of the grass-dominated communities in Mexico. There is great concern about the transformation of these into thornscrub through the action of several interrelated factors, mainly: overgrazing and diminishing fire frequency.

    Why are arid grasslands important?
    The processes of land conversion, modification, and disturbance are of paramount importance to arid grasslands and desertscrub not only ecologically, but also in economical terms because of the use of grasses as forage by livestock. Grasses are well known for their resistance to harsh environmental conditions.

    What types of grasslands are found along a 1100 km transect?
    We choose 10 experimental sites including three different types of grasslands situated along a 1100 km transect from east to west including meadow steppes, typical steppes, and desert steppes across an aridity gradient (from less to more arid; Table S1; Supplementary Fig. 1, 2).

    Are arid grasslands a climatic climax?
    Although a sizable portion of the land designated as Mexican arid grasslands might represent a climatic climax, most of their present area can be ascribed to cultural or biological factors (Rzedowski 1978). The instability of arid grasslands is best exemplified by the major changes that occur once recurrent disturbance agents come into play.

    What is arid land conversion?
    Arid land conversion -the replacement of desertscrub by another vegetation- occurs by deliberate transformation of the land mainly by extirpating the desertscrub to transform it into agricultural land, and by the replacement of the desertscrub by induced grasslands to increase the stocking rate for cattle.
