		The tropical savanna is a biome characterized by tall grasses and occasional trees.
		Large regions of tropical savanna extend through the nations of Botswana, Namibia, and Kenya in Africa, southern Brazil, India, and Australia.
		Savannas exist in areas where there is a 6 to 8 month wet summer season and a dry winter season.

	Tropical savanna
		Rainfall on savanna is between 50 and 150 centimeters (20 to 60 inches) a year, and can be very seasonal, with the entire year's rainfall sometimes occurring within a couple of weeks.
		Although the term "savanna" is believed to have originally come from an Amerindian word describing "land which is without trees but with much grass either tall or short" (Oviedo y Valdes, 1535), by the late 1800s it was used to mean land with both grass and trees.
		Tropical savannas are widespread on the continent of Africa, and are also found in India and the northern parts of South America and Australia.

		Tropical savannas or grasslands are associated with the tropical wet and dry climate type (Koeppen's Aw), but they are not generally considered to be a climatic climax.
		Seasonal forests of the tropics are also widespread and vary along a latitudinal/moisture gradient between the tropical broadleaf evergreen forest of the equatorial zone and the deserts of the subtropics.
		Furthermore, savannas may be distinguished according to the dominant taxon in the tree layer: for example, palm savannas, pine savannas, and acacia savannas.

		The tropical savannas are the landscapes of dense grass and scattered trees that stretch across northern Australia from Broome to Townsville.
		The tropical savannas are also home to an extraordinary variety of plants and animals - and not just in the rainforest patches that dot the region, but also in the grassy woodlands.
		Many factors contribute to this richness, not least of which is the fact that the tropical areas of the world tend to harbour high levels of biodiversity and the fact that north Australia still retains substantial natural habitat for plants and animals.

	savanna_australia
		The Australian tropical savanna is an area of dense grass and scattered trees that stretches across northern Australia from Broome to Townsville.
		A savanna is usually very flat and with few trees and shrubs, this is because the fires destroy most of the trees and shrubs which usually aren't fire resistant.
		Most savannas are near the equator, but the Australian savanna is south of the equator, which causes this region to have summer while we are having fall.

		Tropical Savannas Savannas are part of the Grassland biome, and are generally found in regions dominated by the “Wet-Dry Climate.” Tropical Savannas encompass almost one half of the entire continent of Africa as well as many parts of Australia, India, Mexico, and South America.
		Tropical Savannas are always found in hot weather with a mean temperature of among eighty-five to ninety degrees Fahrenheit, where the annual rainfall is from about twenty to fifty inches per year.
		The main threat to the tropical Savanna is the increasing of the human population.

	Savanna Summary
		Savannas are sometimes a transitional zone, occurring between forest or woodland regions and grassland regions.
		Tropical and subtropical savannas are classified with tropical and subtropical savannas and shrublands as the tropical and subtropical grasslands, savannas, and shrublands biome.
		Mediterranean savannas are mid-latitude savannas in Mediterranean climate regions, with mild, rainy winters and hot, dry summers, part of the Mediterranean forests, woodlands, and shrub biome.

	The grassland biome
		Savannas are always found in warm or hot climates where the annual rainfall is from about 50.8 to 127 cm (20-50 inches) per year.
		The soil of the savanna is porous, with rapid drainage of water.
		For example, in drier savannas such as those on the Serengeti plains or Kenya's Laikipia plateau, the dominant grasses on well-drained soils are Rhodes grass and red oat grass; throughout the East African savannas, star grasses are dominant; the lemon grasses are common in many western Uganda savannas.

		Savannas occur in Australia where there is a 6 to 8 month wet summer season and a dry winter season.
		In savannas, trees have long tap roots to reach the deep water table, and thick bark for resistance to annual fires (thus palms are prominent in many areas).

		You find tropical scrub and thorn forests on the west coast of Mexico, Yucatan peninsula, Venezuela, Brazil; on the northwest coast and central parts of Africa; and in Asia, in Turkestan and India.
		However, it may appear that most plants in the tropics are poisonous because of the great density of plant growth in some tropical areas.

		Tropical rain forests are not a million or more years old -- in fact, in most areas identified as "tropical rain forest," the land has been forested less than 12,000 years.
		Forests are not the normal clothing of the Earth -- dry grasslands and deserts dominate the continents, and tropical savannas alone occupy around one-fifth of the Earth's land surface.
		Nor is the tropical rain forest the richest remaining library of genetic resources or the last refuge of primitive cultures living in harmony with nature.
