Thorn forest

Last updated

A thorny forest is a dense, scrub-like vegetation characteristic of dry subtropical and warm temperate areas with a seasonal rainfall averaging 250 to 500 mm (9.8 to 19.7 in). This vegetation covers a large part of southwestern North America and southwestern Africa and smaller areas in Africa, South America, and Australia. In South America, thorn forest is sometimes called Caatinga , and consists primarily of small, thorny trees that shed their leaves seasonally. Trees typically do not exceed 10 metres (33 ft) in height, usually averaging between 7 and 8 metres (23 and 26 ft) tall. Thorn forest grades into savanna woodland as the rainfall increases and into desert as the climate becomes dryer. [1] Tidal forest consist of thorns in it.

Caatinga Ecoregion (WWF)

Caatinga is a type of desert vegetation, and an ecoregion characterized by this vegetation in interior northeastern Brazil. The name "Caatinga" is a Tupi word meaning "white forest" or "white vegetation".

Savanna Mixed woodland-grassland ecosystem

A savanna or savannah is a mixed woodland-grassland 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 layer consisting primarily of grasses.

Geography of Nigeria

Nigeria is a country in West Africa. Nigeria shares land borders with the Republic of Benin in the west, Chad and Cameroon in the east, and Niger in the north. Its coast lies on the Gulf of Guinea in the south and it borders Lake Chad to the northeast. Noted geographical features in Nigeria include the Adamawa highlands, Mambilla Plateau, Jos Plateau, Obudu Plateau, the Niger River, River Benue and Niger Delta.

Geography of Paraguay

Paraguay is a landlocked country in South America, bordering Brazil, Argentina and Bolivia. The Paraguay River divides the country into strikingly different eastern and western regions. Both the eastern region and the western region gently slope toward and are drained into the Paraguay River, which separates and unifies the two regions. With the Paraneña region reaching southward and the Chaco extending to the north, Paraguay straddles the Tropic of Capricorn and experiences both subtropical and tropical climates.

Geography of Mauritania

Mauritania, a country in the western region of the continent of Africa, is generally flat, its 1,030,700 square kilometres forming vast, arid plains broken by occasional ridges and clifflike outcroppings. It borders the North Atlantic Ocean, between Senegal and Western Sahara, Mali and Algeria. It is considered part of both the Sahel and the Maghreb. A series of scarps face southwest, longitudinally bisecting these plains in the center of the country. The scarps also separate a series of sandstone plateaus, the highest of which is the Adrar Plateau, reaching an elevation of 500 metres. Spring-fed oases lie at the foot of some of the scarps. Isolated peaks, often rich in minerals, rise above the plateaus; the smaller peaks are called guelbs and the larger ones kedias. The concentric Guelb er Richat is a prominent feature of the north-central region. Kediet ej Jill, near the city of Zouîrât, has an elevation of 1,000 metres and is the highest peak.

Geography of Somalia

Somalia is a country located in the Horn of Africa. It is bordered by Ethiopia to the west, Djibouti to the northwest, the Gulf of Aden to the north, the Somali Sea and Guardafui Channel to the east, and Kenya to the southwest. With a land area of 637,657 square kilometers, Somalia's terrain consists mainly of plateaus, plains and highlands. Its coastline is more than 3,333 kilometers in length, the longest of mainland Africa and the Middle East. It has been described as being roughly shaped "like a tilted number seven".

Tropical and subtropical moist broadleaf forests Biome

Tropical and subtropical moist broadleaf forests (TSMF), also known as tropical moist forests, are a tropical and subtropical forest habitat type defined by the World Wide Fund for Nature. The habitat type is sometimes known as jungle.

Veld

Veld, also spelled veldt, is a type of wide open rural landscape in Southern Africa. Particularly, it is a flat area covered in grass or low scrub, especially in the countries of South Africa, Lesotho, Swaziland, Zimbabwe and Botswana. A certain sub-tropical woodland ecoregion of Southern Africa has been officially defined as the Bushveld by the World Wide Fund for Nature. Trees are found only in a few places—frost, fire and grazing animals allow grass to grow but prevent the growth of trees.

Temperate rainforest Forests in the temperate zone with heavy rainfall

Temperate rainforests are coniferous or broadleaf forests that occur in the temperate zone and receive heavy rainfall.

Deccan thorn scrub forests

The Deccan thorn scrub forests are a xeric shrubland ecoregion of south India and northern Sri Lanka. Historically this area was covered by tropical dry deciduous forest, but this only remains in isolated fragments. The vegetation now consists of mainly of southern tropical thorn scrub type forests. These consist of open woodland with thorny trees with short trunks and low, branching crowns; spiny and xerophytic shrubs; and dry grassland. This is the habitat of the great Indian bustard and blackbuck, though these and other animals are declining in numbers; this area was at one time home to large numbers of elephants and tigers. Almost 350 species of bird have been recorded here. The remaining natural habitat is threatened by overgrazing and invasive weeds, but there are a number of small protected areas which provide a haven for the wildlife.these trees in these forests have adapted and do not require that much water.

Chala desert in South America

The Chala or "Coast" is one of the eight natural regions in Peru. It is formed by all the western lands that arise from sea level up to the height of 500 meters. The coastal desert of Peru is largely devoid of vegetation but a unique fog and mist-fed ecosystem called Lomas is scattered among hills near the Pacific coast as elevations up to 1,000 metres (3,300 ft).

Wildlife of Botswana

The wildlife of Botswana refers to the flora and fauna of Botswana. Botswana is around 90% covered in savanna, varying from shrub savanna in the southwest in the dry areas to tree savanna consisting of trees and grass in the wetter areas. Even under the hot conditions of the Kalahari Desert, many different species survive; in fact the country has more than 2500 species of plants and 650 species of trees. Vegetation and its wild fruits are also extremely important to rural populations living in the desert and are the principal source of food, fuel and medicine for many inhabitants.

Wildlife of Burundi

The wildlife of Burundi is composed of its flora and fauna. The small, landlocked country is home to 2,950 species of plants, 596 birds, 163 species of vertebrates, 52 species of reptiles, 56 species of amphibians, and 215 fish species. The wildlife has been drastically reduced in recent years, mainly on account of intense population pressure, conversion of large areas of forest into agricultural land, and extensive livestock farming. The protected area encompasses little more than 5% of the total area of the country.

Wildlife of Djibouti

The Wildlife of Djibouti, consisting of flora and fauna, is in a harsh landscape with forest accounting for less than one percent of the total area of the country. The flora and fauna species are most found in the northern part of the country in the ecosystem of the Day Forest National Park at an average altitude 1,500 metres (4,900 ft), including the massif Goda, with a peak of 1,783 metres (5,850 ft). It covers an area of 3.5 square kilometres (1.4 sq mi) of Juniperus procera forest, with many of the trees rising to 20 metres (66 ft) height. This forest area is the main habitat of critically endangered and endemic Djibouti francolin, and another recently noted vertebrate, Platyceps afarensis. The area also contains many species of woody and herbaceous plants, including boxwood and olive trees, which account for sixty percent of the total identified species in the country.

Wildlife of South Africa

The wildlife of South Africa consists of the flora and fauna of this country in southern Africa. The country has a range of different habitat types and an ecologically rich and diverse wildlife, vascular plants being particularly abundant, many of them endemic to the country. There are few forested areas, much savanna grassland, semi-arid Karoo vegetation and the fynbos of the Cape Floristic Region. Famed for its national parks and big game, 297 species of mammal have been recorded in South Africa, as well as 858 species of bird and over 20,000 species of vascular plants.

Climate of South Africa

The climate of South Africa is determined by South Africa's situation between 22°S and 35°S, in the Southern Hemisphere's subtropical zone, and its location between two oceans, Atlantic and the Indian.

Natural history of Mount Kenya

The flora and fauna of Mount Kenya are diverse, due to the variation in altitude, rainfall, aspect and temperature. The mountain slopes can be divided into vegetation zones, with each zone having different dominant plant species. Although many plants on Mount Kenya have local names, here they are reported only with their English and scientific names.

<i>Vachellia reficiens</i> species of plant

Caquetá moist forests

The Caquetá moist forests (NT0107) is an ecoregion of tropical moist broad leaf forest to the east of the Andes in the east of Colombia, with a small section in Brazil, in the Amazon biome. The forests are in the transition between the Guiana and Amazon regions, and have highly diverse flora and fauna. They are relatively intact, although they are mostly unprotected and are threatened with deforestation to create cattle pastures.

Paraguana xeric scrub

The Paraguana xeric scrub (NT1313) is an ecoregion in Venezuela to the north and east of Lake Maracaibo along the Caribbean coast. The region holds flora and fauna adapted to the very dry conditions of the coastal dunes and inland areas of bush, scrub, briars and cacti. There are several endangered species of animals and birds. Efforts at protecting the environment have been ineffective. Most of the original trees have been cut down, dunes are being destabilized by loss of vegetation, scrub is replaced by farmland and vegetation is destroyed by grazing goats.

La Costa xeric shrublands

The La Costa xeric shrublands (NT1309) is an ecoregion in Venezuela that stretches along the Caribbean coast. The dry scrub and savanna has been subject to modification since the 16th century by European colonists who replaced it by a patchwork of farm fields and pasturage. Little of the original habitat remains.
