Vegetation is an assemblage of plant species and the ground cover they provide. [2] It is a general term, without specific reference to particular taxa, life forms, structure, spatial extent, or any other specific botanical or geographic characteristics. It is broader than the term flora which refers to species composition.
A desert is a region of land that is very dry because it receives low amounts of precipitation (usually in the form of rain, but it may be snow, mist or fog), often has little coverage by plants, and in which streams dry up unless they are supplied by water from outside the area. [9]
A grass savanna at Kruger National Park in South Africa. A savanna or savannah is a mixed woodland - grassland (i.e. grassy woodland) biome and ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous ...
Mangrove forests, also called mangrove swamps, mangrove thickets or mangals, are productive wetlands that occur in coastal intertidal zones. [1][2] Mangrove forests grow mainly at tropical and subtropical latitudes because mangrove trees cannot withstand freezing temperatures. There are about 80 different species of mangroves, all of which grow ...
Extent of deserts and xeric shrublands. Deserts and xeric shrublands are a biome defined by the World Wide Fund for Nature. [ 1 ] Deserts and xeric (Ancient Greek ξηρόςxērós 'dry') shrublands form the largest terrestrial biome, covering 19% of Earth 's land surface area. [ 2 ] Ecoregions in this habitat type vary greatly in the amount of ...
The Tundra of North America is a Level I ecoregion of North America designated by the Commission for Environmental Cooperation (CEC) in its North American Environmental Atlas. One of the planet's most recent biomes, a result of the last ice age only 10,000 years ago, the tundra contains unique flora and fauna formed during the last glaciation ...
In total, 37.3% of the Cerrado has already been totally converted to human use, while an additional 41.4% is used for pasture and charcoal production. The gallery forests in the region have been among the most heavily affected. It is estimated that only about 432,814 km 2, or 21.3% of the original vegetation, remains intact today. [39]
Tall shrubs are mostly 2–8 m high, small shrubs 1–2 m high and subshrubs less than 1 m high. [3] There is a descriptive system widely adopted in Australia to describe different types of vegetation is based on structural characteristics based on plant life-form, plus the height and foliage cover of the tallest stratum or dominant species.
