Grasslands also called Greenswards are areas where the vegetation is dominated by grasses and other herbaceous non-woody plants.

Ecosystem: It’s Structure and Functions (With Diagram)

In addition, grasslands provide important services and roles including as water catchments, biodiversity reserves, for cultural and recreational needs, and potentially a carbon sink to alleviate The producers fix the solar energy and produce the. From a global perspective, the distribution of grassland is largely a function of climate, particularly climatic factors that influence soil moisture availability. Effective moisture annual precipitation minus annual potential evapotranspiration is a useful index of those factors, although it neglects important seasonal variations in moisture supply. Grassland, area in which the vegetation is dominated by a nearly continuous cover of grasses. Grasslands occur in environments conducive to the growth of this plant cover but not to that of taller plants, particularly trees and shrubs. The factors preventing establishment of such taller, woody vegetation are varied.


Grasslands (also called Greenswards) are areas where the vegetation is dominated by grasses and other herbaceous (non-woody) plants. Grasslands (also called Greenswards) are areas where the vegetation is dominated by grasses and other herbaceous (non-woody) plants.


Pdf Importance And Functions Of Grasslands

The grassland is an open terrestrial community covered with grasses. It has varieties of organisms that are interacting together as well as they interact with their physical environment. The major grasslands in the world are developed in the temperate region.

Grasslands are areas 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, grasslands are one of the largest biomes on earth and dominate the landscape worldwide. There are different types of grasslands: natural grasslands, semi-natural grasslands, and agricultural grasslands.

Carabid Coleoptera: Carabidae assemblages are strongly influenced by habitat structure, especially as reflected by vegetation and soil characteristics Koivula et al. For these reasons, carabid distributional patterns and community structure can be strongly affected by land-use changes Eyre et al. For example, soil bulk density SBD; an indicator of soil structure, also used to estimate soil compaction, Rabot et al. Vegetation composition and diversity also impact carabid community structure Koricheva et al. Within local environmental characteristics, in addition to vegetation and soil characteristics, climate plays an important role in carabid ecology.

An organism is always in the state of perfect balance with the environment. The environment literally means the surroundings. The environment refers to the things and conditions around the organisms which directly or indirectly influence the life and development of the organisms and their populations.

The major grassland ecosystems of the world are the great plains of Canada and United States, S. Argentina to Brazil and S. Asia to Central Asia. These include the nutrients present in the soil and the aerial environment.
