The Australian Mediterranean biome is charac­terized by numerous types of birds and animals. It grows during the very short summer. Africa’s basic vegetational zones are believed to have existed in approximately the same climatically controlled series and with the same characteristically developed species for a long period of time; indeed, some ancient African plant families—such as the cycads, which evolved some 200 million years ago—still have living representatives. This region constitutes the southern counterpart of the Mediterranean zone, although (with the exception of the Atlas Mountains) it is richer in its vegetation potential. : There are several species of oak in the European Mediterranean biome. In earlier times, African cultivators found the fabric of the tropical rainforest comparatively difficult to modify substantially. These consist of a succession of colder periods marked by glacial advances, interrupted by warmer, drier interglacials; the last series of these ended between about 5,000 and 10,000 years ago. Answer: (c) Tundra vegetation The growth of natural vegetation is very limited in the tundra vegetation. There are about 201 species of vertebrate ani­mals in south California, of which about 75 percent are bird species. For example, quagga, a type of zebra, which was an important species, now has be­come totally extinct whereas bontebok, a type of ante­lope, has now become a rare species and has been pushed to remote areas. 3. It is found bathing the coasts of Algeria, Greece, Bosnia and Herzegovina, Croatia, Egypt, France, Israel, Italy, and other countries. 4. Prohibited Content 3. It is mostly found in areas around the Mediterranean Sea in Europe, Africa and Asia. Before uploading and sharing your knowledge on this site, please read the following pages: 1. Garigue characteristically is found on limestone soils and has more woody growth, including evergreen and cork oaks (Quercus suber). (iii) Burning of vegetation transforms the organic matter into ashes and thus facilitates the mineralisation of organic matter and ultimately makes the mineralised organic matter available to plant roots. Much is known of the detailed processes of vegetation modification along the Mediterranean, since they have been observed and studied since Classical times, and a good deal is also known from the more than three centuries of study of the Cape area of South Africa, but until the late 19th century very little was understood about these processes in tropical Africa. This climate has a profound influence on the vegetation and wildlife of the region. During the wetter times (pluvials) in Africa, equatorial forests spread, separating northern woodlands from their southern counterparts (with consequent species differentiation); mountain vegetation descended onto the plateaus; and there is evidence that the Saharan climate was greatly ameliorated, much to the advantage of humans. Although grassy tracts occur on the mountains, they are characteristically unusual lower down. Vegetation types range from forests to woodlands, savannas, shrublands, and grasslands; "mosaic habitat" landscapes are common, where differing vegetation types are interleaved with one another in complex patterns created by variations in soil, topography, exposure to wind and sun, and fire history. vegetation and wildlife of the region. Animal Community 5. It grows during the very short summer. The ground layer is dominated by herba­ceous plants and grasses. The Euro­peans largely removed the original forests for the purpose of agriculture and thus there developed the secondary succession of vegetation which now has taken the form of present-day fymbos. The average temperature during cool winter season ranges between 5°C and 10°C whereas mean summer temperature varies from 20°C to 27°C and thus the annual range of temperature becomes 15°C to 17°C or even more. Hyraxes, baboons, and leopard and found in small number only in the mountainous areas. The Mediterranean vegetation community con­sists of a variety of sclerophyll plant formation classes which range from Mediterranean mixed evergreen forests (in the coastal lands immediately bordering the aseas and the oceans) to woodland, dwarf forest and scrubs. (iv) Fire de­stroys poisonous compounds secreted by plant roots. The long-term effects of such activity bear directly upon the debated question of the origin of the savannas. Mediterranean vegetation c. tundra vegetation d. coniferous forests Q. There are numerous animals in these two regions because of abundant supply of food from the good cover of vari­ous types of shrubs. There are numerous animals in the malle scrubs. The mammals are now dominated by ground squirrels, wood rats and mule deers. The most diverse and seemingly inexhaustible floral realm in Africa has therefore become a cause for widespread concern. Mediterranean forest climate; The Mediterranean climate is characterized by mild winters, warm autumns, rainy springs and dry summers , in which forest fires abound, to which the vegetation is adapted (pyrophilic vegetation). It was formed by geological movements. 3. MCQ Questions for Class 7 Social Science with Answers were prepared based on the latest exam pattern. These regions are marked by hot dry summers and mild rainy winters. This kind of vegetation is also found outside the actual Mediterranean region in California in USA, south west Africa, south west South America and South west Australia. The plants of the Mediterranean biome have also developed special types of root systems in accord­ance with the regional environmental conditions mainly the availability of moisture. Its total area is 970,000 square miles, and its greatest depth is off the coast of Greece, where it is 16,800 feet deep. Check the below NCERT MCQ Questions for Class 7 Geography Chapter 6 Natural Vegetation and Wild Life with Answers Pdf free download. The continuous grazing, natural and anthropogenic frequent fires and felling of trees have largely transformed the shrub community called as maquis into garrigue. The typical birds of the shrub habitats and grasslands are honeyeaters, whistlers, wrens, robins, quail-thrushes etc. Content Filtration 6. Content Guidelines 2. In its southern part it is linked to the Red Sea by means of the Suez Canal. It is also very capricious with sudden heavy rain or bouts of high winds such as the Sirocco and Mistral. For example, some plants have extensive root systems with strong tap root which extends even into the consolidated parent rocks (such as the roots of almond); some plants have such root systems which develop above the ground as well as quite deep inside the ground (such as the root of chamise); some plants have bulbous or tuber roots (such as the geophyte plants, e.g. There are some regional variations in the spe­cies composition and vertical structure of the vegeta­tion community in the various parts of the Mediterra­nean biomes as given below: European Mediterranean Biome is character­ized by multi-layered structural pattern of the vegeta­tion community wherein three distinct layers (strata) have developed. The recurrent burn­ing of vegetation has certain positive ecological results e.g. This region constitutes the southern counterpart of the Mediterranean zone, although (with the exception of the Atlas Mountains) it is richer in its vegetation potential. Vegetation Community 4. For example, soil structure is changed by frequent fires and thus is subjected to accelerated rate of soil erosion during the rainstorms. Conse­quently, the leaves have developed sclerophyllous characteristics wherein they are stiff and hard and the stems have thick barks. The average net primary productivity (NPP) of the Mediterranean biome is about 700 dry gram per square metre per year whereas the total net primary production of all parts of the Mediterranean biome is 6xl09 tons per year. Physically and biologically, Madagascar has long formed a separate entity. The second or the middle layer is formed of shrubs which include the species like Arbutus, Pistacia, Rhammus, Ceratonia etc. state two features of this type of vegetation Get the answers you need, now! The plants of the Mediterranean biome have developed several morphological characteristics to withstand dry conditions. The NPP of 700 dry gram per square metre per year generates a biomass of 6000 grams per square metre. Pastoralism, agriculture, the rapid growth of human and livestock populations, the expansion of cities and towns, and the external demands for primary resources have made ever-greater demands upon the land for sustenance and perceived economic betterment. During the warmer, drier interpluvials the existing vegetation was degraded in many zones. The Mediterra­nean biomes of California and Chile are characterized by more or less similar animal species. There are numerous varieties of wallaby and mice. Mean annual rainfall ranges be­tween 370mm and 650mm, the most portions of which is received during winter season. It has a luxuriant vegetation of all kinds – trees, shrubs, and creepers giving it a multilayered structure. In India, evergreen forests are found in the western slopes of the Western Ghats in States such as Kerala and Karnataka. different types of flowers like dahlia) etc. In other words, the plants, after burn­ing, bear luxuriant growth of new branches, shoots and leaves. Large tracts have been degraded into maquis (macchie), garigue, or dry semidesert (steppe) vegetation. The Mediterranean climate is characterized by dry and hot summer and cold and rainy winter. The tallest species of eucalyptus is karri. The Madagascar rainforest has shorter trees and a somewhat drier climate than its equatorial counterpart and contains its own dwarf palms (Dypsis) and bamboos (Ochlandra). The island has much degraded secondary forest (locally called savoka) along the eastern and northern coasts. There is a common practice to burn the vegetation each year or after two or three years after heavy grazing and browsing by sheep and goats. For a region that takes its name from the sea it surrounds, the Mediterranean is surprisingly hilly. Several other places around the world also experience this same climate because they have similar causes of climate. The past million years have been a time of unusually rapid changes, with major consequences for Africa’s vegetation. Similarly, vegetations are burnt in every part of the mediterranean biomes. The regions are located in the western parts of the continent between 30 and 45 degrees north and south of the equator. These shrubs provide valuable forages to the animals and valuable products to human beings like gums, resins, tannins, dyes etc. Native plants are often dormant in the summer, induced by heat and a lack of soil moisture, with the exception of foggy coastal regions. This is an essay about vegetation typical of a Mediterranean climate. On average, the temperature is maintained above 20 ° C , presenting seasonal variations. Climate Controls: Migration of Wind & Pressure Belts - climate results from transitional nature of pressure & winds in these latitudes. History of Mediterranean Sea. Name the fruits found in Mediterranean vegetation. Regions where few plants grow have a low vegetation index, shown in tan. Hunters, pastoralists, and cultivators have all fired the land for centuries and have gathered wild foodstuffs, thatch timber for construction, and fuelwood from the volunteer (i.e., uncultivated or self-generating) vegetation. Many of the predator species like wolf and mountain lion, diversivores like grizzly bear have now become rare species because of increasing pressure of man on the Mediterranean vegetation. Besides burning of vegetation, mass clearance of natural veg­etation for agricultural and commercial purposes, overgrazing of grasslands and large-scale hunting of animals have led to elimination of certain animal species, accelerated rate of soil erosion, increase in the silt load of major rivers and alteration of original natural vegetation, habitats and micro-climates. The winter rainfall is received through the cyclonic storms associated with the westerlies. We have Provided Natural Vegetation and Wild Life Class 7 Geography MCQs Questions with Answers to help students understand the concept very well. Only a few species of antelope like duiker and steenbuck are found only in the dense cover of fymbos. They emphasize with abundance of migratory birds, migrate in summer to climates less hot and dry and others in winter. Mediterranean forest location; The mallee forests are Mediterranean forests found in Australia. The vegetation community is dominated by trees and shrubs.
