What are the four types of vegetation in Africa?
Though the vegetation categorization in Africa was varied, this work focuses on the five major groups of vegetation that is forest, woodlands and shrub lands, grass lands, agricultural land, and swampy and mangrove vegetation.
What are the four importance of vegetation?
Vegetation provides wildlife habitat and food. Vegetation provides direct (e.g., timber) and indirect (e.g., watershed protection) socioeconomic products and services for humans. Vegetation gives spiritual and cultural experiences to some people.
What are the four main types of vegetation in Western Africa?
The natural vegetation in West Africa ranges from short grass at the desert border to humid rain forests at the southern border of the region near the Atlantic coast. The area in between is occupied by several vegetation zones ranging from tropical forests, to woodland, sa- vanna, shrubs, and short grass.
What are the major types of natural vegetation in Ethiopia?
Phytogeographically, Ethiopia comprises diverse vegetation types, including the tropical lowland rainforest in the southwest, arid and semi-arid dry woodlands in the East, and the Afroalpine forests in the north and southeast.
What are the five types of vegetation?
Specific areas that are home to different plants and animal species come in five different forms: forests, grasslands, tundras, deserts, and ice sheets .
How do we define what type of vegetation we are dealing with?
The way we define what type of vegetation we are dealing with is by analyzing the dominant species occupying and creating the area. 5. Forests. Forests can emerge in almost any kind of terrain, and they can develop anywhere between sea level and high mountain ranges.
Why do temperate grasslands change?
This means that in temperate grasslands, the vegetation changes accordingly because some species prefer to grow during summertime, while others come to life when it is cold.
What is the tundra landscape?
Tundras. Autumn greenlandic orange tundra landscape with lakes and mountains in the background, Kangerlussuaq, Greenland. Tundras appear in climate zones where the temperatures are mostly low, and unlike the previous two types of vegetation, their diversity of the population is much smaller. There are two different types ...
Where do tropical forests grow?
Tropical forests usually grow in the tropics (close to the Earth’s equator), while boreal forests generally thrive in much colder conditions (close to the Arctic). 4. Grasslands. Open Prairie Grasslands in Tibetan Amdo Region of Central China. This type of vegetation can be found everywhere on Earth, except for Antarctica, ...
What is the most important factor that creates a forest?
The most important factor that creates a forest is, of course, the trees. But, for something to be classified as a forest, the density of the trees and their leaves must have the ability to cover the ground, or better to say, to create shade to everything that is underneath them.
Do forests have more than one tree?
Although the vast majority of forests have a mixed population of trees, meaning there is almost always more than one type of tree growing in a particular area, we can also differentiate types of forests.
What is the vegetation type of Australia?
Tropical savanna is the predominant vegetation type across the northern quarter of Australia where rainfall is above 600 mm yr −1, an area of ∼2 million km 2 ( Figures 1a, 1b, and 2 ). These savannas are open woodlands and open forests, with tree cover declining as rainfall decreases with distance from the northern coast. The overstorey flora is typically dominated by Eucalyptus spp., particularly Eucalyptus tetrodonta, E. dichromophloia, and E. miniata. Melaleuca viridiflora, M. nervosa, and E. pruinosa assemblages occur in the drier regions of this biome where annual rainfall <1000 mm yr −1. The ground layer is dominated by annual and perennial grasses from the Sarga, Heteropogon, and Schizachrium genera. A variety of other tall grasses (>1 m height) dominate the ground layer of the monsoonal savannas, which extend from Western Australia to the Cape York Peninsula in Queensland. Heteropogon contortus (black speargrass) dominates the tropical savanna understory in eastern Queensland, with Themeda triandra, Aristida, Bothriochloa, and Chrysopogon bladhii becoming more dominant as rainfall declines. Acacia -dominated savanna communities include extensive areas of brigalow ( A. harpophylla ), lancewood ( A. shirleyi ), and gidgee A. cambegei and A. georginae ).
How does vegetation affect the trophic system?
Vegetation type exerts continuing influence up the trophic system to the natural enemies of insect herbivores. As vegetational succession proceeds from herbs to shrubs to trees, so the number of parasitoids per host insect increases (Askew, 1980; Hawkins and Lawton, 1987; Hawkins, 1988).
What are the savannas in South America?
The neotropical savannas of South America cover more than 2 million km 2. The Brazilian cerrado and the Colombian and Venezuelan llanos are a continuous formation, interrupted by narrow gallery forests. The cerrada ̃ o includes a range of vegetation formations from the pure or almost pure grassland of camp limpo, to open woodland with scattered tree cover of campo cerrado. These savanna can grade into denser woodland or open forests, the cerrada ̃ o, where tree cover is greater than 50%. The dominant grasses are Andropogon, Aristida, Paspalum, and Trachypogon. The Orinoco llanos comprise grasslands or grasslands with scattered trees which are typically <8 m tall. Common trees include Byrsonima spp. Curatella americana, Bowdichia virgioides, and grasses include Trachypogon and Andropogon. Hyper-seasonally flooded savannas and esteros (savanna wetland) occur in Brazil and Bolivia. Other savanna types, such as savanna parkland and mixed woodland, occur through tropical America.
What are the vegetation types on the Pantepui mountain?
Depending essentially on the size of the summit surface, many of these plateaus are covered by a great variety of vegetation types. The main components of Pantepui-summit vegetation vary from tiny lichen crusts sticking on the rock surface to extensive Stegolepis or bromeliad fields on peat, and up to 15-m tall cloud forests with gnarled trees and a dense, almost impenetrable understory. In several tepuis, however, the summit region is connected to the lower base of the mountain by more or less steep ledges or narrow slope habitats; frequently one finds there taller plant communities, ranging from a few low epipetric cushions to small, chasmophytic shrubbery and, eventually, to gnarled low woods with small crowns (e.g., Bonnetia roraimae ). Therefore not all tepui summits are totally isolated from their lowland forests or savannas at the base ( Huber, 1988 ). So far, however, a detailed botanical and ecological study of these interesting and unique lowland–upland–highland connections in the Guianan tepui landscape has not been made.
What are the main ecosystems in the Mediterranean?
Main Ecosystem Types. The vegetation types usually considered as ‘typically Mediterranean’ are the evergreen and sclerophyllous shrublands or heathlands, named maquis and garrigue in the Mediterranean Basin, chaparral in California, matorral in Chile, fynbos in SW Africa, kwongan and mallee in SW Australia.
What is a presteppic forest?
Presteppic forest types, very frequent in southern and eastern Mediterranean, consist of open-vegetation structures dominated by nonforest plant species under scattered trees. Nonforest species are steppe-type perennial species that can eventually be replaced by ruderal annual species when grazing occurs. Presteppes are most frequent under warm and hot temperature variants of arid (and sometimes semiarid) bioclimates. They gradually merge into steppes under hotter and drier conditions. On mountains, presteppes are a transitional vegetation structure from forests (or preforests) to high-elevation steppes dominated by low and scattered cushion-like spiny xerophytes.
What are the Mediterranean forests?
True Mediterranean forests are rare and they represent 1.8% of world’s forest area. Northern Hemisphere Mediterranean forests show a higher structural and species diversity than those of the Southern Hemisphere, because the latter cover less extensive areas and, as in South Africa, may be outside the range of Mediterranean bioclimate. The Southern Cape forests are very patchy with mainly subtropical sclerophyllous trees and conifers ( Afrocarpus, Podocarpus ). Forests of Mediterranean Chile are more diverse due to the strong latitudinal gradient and the increase in rainfall from north to south; semiarid Acacia caven and Prosopis chilensis forests in the north are succeeded by subtropical broad-leaved and sclerophyllous forests in central Chile, and by deciduous Nothofagus forests farther south. Together with species-rich sclerophyllous shrublands (kwongan and mallee), the forests and woodlands of SW Australia are dominated by Eucalyptus, Acacia, and Casuarina on poor sandy soils, where mean annual rainfall exceeds 400 mm; several types of Australian woody vegetation are distinguished according to the foliage cover of tallest stratum and the high of the trees.
