Savanna forest report

Savannah Forest A savanna, or savannah, is a grassland ecosystem characterized 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 layer consisting primarily of grasses. The oak savanna is a common type of savanna in the Northern Hemisphere. Some classification systems also recognize a grassland savanna from which trees are absent. This article deals only with savanna under the common definition of grassy woodland with a significant woody plant component. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in forest. Savannas are also characterized by seasonal water availability, with the majority of rainfall confined to one season. Savannas are associated with several types of biomes. Savannas are frequently in a transitional zone between forest and desert or grassland. Savanna covers approximately 20% of the Earth's land area. Many grassy landscapes and mixed communities of trees, shrubs, and grasses were described as savanna before the middle of the 19th century, when the concept of a tropical savanna climate became established. The KÜppen climate classification system was strongly influenced by effects of temperature and precipitation upon tree growth, and his oversimplified assumptions resulted in a tropical savanna classification concept which resulted in it being considered as a "climatic climax" formation. The common usage meaning to describe vegetation now conflicts with a simplified yet widespread climatic concept meaning. The divergence has sometimes caused areas such as extensive savannas north and south of the Congo and Amazon Rivers to be excluded from mapped savanna categories. "Barrens" has been used almost interchangeably with savanna in different parts of North America. Sometimes mid-western savanna was described as "grassland with trees". Different authors have defined the lower limits of savanna tree coverage as 5–10% and upper limits range as 25–80% of an area. Two factors common to all savanna environments are rainfall variations from year to year, and dry season wildfires. In the Americas, e.g. in Belize, Central America, savanna vegetation is similar from Mexico to South America and to the Caribbean.


Following species are available in our model Savannah forest (made in 2014) as part of Project Biodiversity Park: Lion, Giraffe, Ostrich, Warthog, Gorilla and Cheetah


Lion Binomial name Panthera (Linnaeus, 1758)

leo

The lion (Panthera leo) is one of the four big cats in the genus Panthera and a member of the family Felidae. With some males exceeding 250 kg (550 lb) in weight, it is the secondlargest living cat after the tiger. Wild lions currently exist in sub-Saharan Africa and in Asia (where an endangered remnant population resides in Gir Forest National Park in India) while other types of lions have disappeared from North Africa and Southwest Asia in historic times. Highly distinctive, the male lion is easily recognised by its mane, and its face is one of the most widely recognised animal symbols in human culture. Traditionally, 12 recent subspecies of lion were recognised, distinguished by mane appearance, size, and distribution. Lion coloration varies from light buff to yellowish, reddish, or dark ochraceous brown. The underparts are generally lighter and the tail tuft is black. Lions are the only members of the cat family to display obvious sexual dimorphism – that is, males and females look distinctly different. The lioness is the one who does the hunting for the pride. The male lion associated with the pride usually stays and watches it’s young while waiting for the lionesses to return from the hunt. Lions are powerful animals that usually hunt in coordinated groups and stalk their chosen prey. The prey consists mainly of large mammals, with a preference for wildebeest, zebras, buffalo, and warthogs in Africa and nilgai, wild boar, and several deer species in India. Many other species are hunted, based on availability. Lions hunting in groups are capable of taking down most animals, even healthy adults, but in most parts of their range they rarely attack very large prey such as fully grown male giraffes due to the danger of injury.

Giraffe Binomial name Giraffa camelopardalis (Linnaeus, 1758) The giraffe (Giraffa camelopardalis) is an African even-toed ungulate mammal, the tallest living terrestrial animal and the largest ruminant. Fully grown giraffes stand 5–6 m (16–20 ft) tall, with males taller than females. The average weight is 1,192 kg (2,628 lb) for an adult male and 828 kg (1,825 lb) for an adult female. Despite its long neck and legs, the giraffe's body is relatively short. Located at both sides of the head, the giraffe's large, bulging eyes give it good all-round vision from its great height. Giraffes see in color and their senses of hearing and smell are also sharp. The animal can close its muscular nostrils to protect against sandstorms and ants. The giraffe's prehensile tongue is about 50 cm (20 in) long. It is purplish-black in color, perhaps to protect against sunburn, and is useful for grasping foliage, as well as for grooming and cleaning the animal's nose. The upper lip of the giraffe is also prehensile and useful when foraging. The lips, tongue and inside of the mouth are covered in papillae to protect against thorns. The coat has dark blotches or patches (which can be orange, chestnut, brown or nearly black in color separated by light hair (usually white or cream in color). Male giraffes become darker as they age. The coat pattern serves as camouflage, allowing it to blend in the light and shade patterns of savanna woodlands. Giraffes usually inhabit savannas, grasslands and open woodlands. Giraffes browse on the twigs of trees, preferring trees of genera Acacia, Commiphora and Terminalia, which are important sources of calcium and protein to sustain the giraffe's growth rate. They also feed on shrubs, grass and fruit.

Ostrich Binomial name Struthio Linnaeus, 1758

camelus

The Ostrich or Common Ostrich (Struthio camelus) is either one or two species of large flightless birds native to Africa, the only living member(s) of the genus Struthio, which is in the ratite family. Ostriches usually weigh from 63 to 145 kilograms (139–320 lb),Ostriches of the East African race (S. c. massaicus) averaged 115 kg (254 lb) in males and 100 kg (220 lb) in females, while the nominate subspecies was found to average 111 kg (245 lb) in unsexed adults. The feathers of adult males are mostly black, with white primaries and a white tail. However, the tail of one subspecies is buff. Females and young males are greyish-brown and white. The head and neck of both male and female ostriches is nearly bare, with a thin layer of down. The skin of the female's neck and thighs is pinkish gray, while the male's is blue-gray, gray or pink dependent on subspecies. Ostriches prefer open land and are native to the savannas and Sahel of Africa, both north and south of the equatorial forest zone. They mainly feed on seeds, shrubs, grass, fruit and flowers; occasionally they also eat insects such as locusts. Lacking teeth, they swallow pebbles that act as gastroliths to grind food in the gizzard. Ostriches can go without drinking for several days, using metabolic water and moisture in ingested plants, but they enjoy liquid water and frequently take baths where it is available.

Warthog Binomial name Phacochoerus (Gmelin, 1788)

africanus

The warthog or common warthog (Phacochoerus africanus) is a wild member of the pig family (Suidae) found in grassland, savanna, and woodland in sub-Saharan Africa The warthog is the only pig species that has adapted to grazing and savanna habitats. The warthog is medium-sized species; their head-andbody lengths range from 0.9 to 1.5 m (3.0 to 4.9 ft) and shoulder height is from 63.5 to 85 cm (25.0 to 33 in). Females, at 45 to 75 kg (99 to 165 lb), are typically a bit smaller and lighter in weight than males, at 60 to 150 kg (130 to 330 lb). A warthog is identifiable by the two pairs of tusks protruding from the mouth and curving upwards. The lower pair, which is far shorter than the upper pair, becomes razor sharp by rubbing against the upper pair every time the mouth is opened and closed. Its diet is omnivorous, composed of grasses, roots, berries and other fruits, bark, fungi, insects, eggs and carrion. The diet is seasonably variable, depending on availability of different food items.

Gorilla Type species Troglodytes Savage, 1847

gorilla

Gorillas constitute the eponymous genus Gorilla, the largest extant genus of primates by size. They are ground-dwelling, predominantly herbivorous apes that inhabit the forests of central Africa. Gorillas move around by knuckle-walking, although they sometimes walk bipedally for short distances while carrying food or in defensive situations. Wild male gorillas weigh 135 to 180 kg (298 to 400 lb) while adult females usually weigh half as much as adult males at 68–113 kg (150–249 lb). The eastern gorilla is more darkly colored than the western gorilla, with the mountain gorilla being the darkest of all. The mountain gorilla also has the thickest hair. The western lowland gorilla can be brown or grayish with a reddish forehead. In addition, gorillas that live in lowland forests are more slender and agile than the more bulky mountain gorillas. The eastern gorilla also has a longer face and broader chest than the western gorilla. A gorilla's day is synchronized, divided between rest periods and travel or feeding periods. Diets differ between and within species. Mountain gorillas mostly eat foliage, such as leaves, stems, pith, and shoots, while fruit makes up a very small part of their diets. Eastern lowland gorillas have more diverse diets, which vary seasonally. Leaves and pith are commonly eaten, but fruits can make up as much as 25% of their diets.

Geoffroy, 1852


Cheetah Binomial name Acinonyx (Schreber, 1775)

jubatus

The cheetah (Acinonyx jubatus) is a large feline (family Felidae, subfamily Felinae) inhabiting most of Africa and parts of the Middle East. It is the only extant member of the genus Acinonyx. The cheetah can run faster than any other land animal— as fast as 112 to 120 km/h (70 to 75 mph). The cheetah's chest is deep and its waist is narrow. The coarse, short fur of the cheetah is tan with round black spots measuring from 2 to 3 cm (0.79 to 1.2 in) across, affording it some camouflage while hunting. There are no spots on its white underside, but the tail has spots, which merge to form four to six dark rings at the end. The tail usually ends in a bushy white tuft. The cheetah has a small head with high-set eyes. The cheetah thrives in areas with vast expanses of land where prey is abundant. The cheetah likes to live in an open biotope, such as semidesert, prairie, and thick brush, though it can be found in a variety of habitats. In Namibia, for example, it lives in grasslands, savannahs, areas of dense vegetation, and mountainous terrain. The cheetah is a carnivore, eating mostly mammals under 40 kg (88 lb), including the Thomson's gazelle, the Grant's gazelle, the springbok and the impala. The young of larger mammals such as wildebeests and zebras are taken at times, and adults too, when cheetahs hunt in groups.
