Tropical Grasslands

Savannas

Tropical Grasslands Background

Grasslands are lands covered with grass, simple as that. Grasslands are usually warm. They are not as dry as deserts. But they are drier than forests. Not many shrubs or trees grown in the grassland.That is because there is not enough water in this biome for them to grow.Tropical grasslands are also known as savannas. Tropical grasslands can be found in Australia, India, Africa, and South America. They surround tropical forests.There is a warm and wet summer season. There is also a cooler winter season. Winter is long and dry. Fires burn through grasslands during the dry season.

Location Of Grasslands Around The World

The location of the Grasslands around the world are located near the equator. They cover the majority of Africa and and large areas in Australia and parts of South America and India. The Savanna is the most known tropical grassland around the world by covering much of Africa. There are also llanos in Colombia and Venezuela, campos of the Brazilian highlands, pantanals of Upper Paraguay, plains in Australia and the Deccan Plateau of India. They are usually found in the interior of continents and have such rich soil.

Organisms and Evolution

Grassland biomes are heavily dominated by grasses as tall as 3 to 6 feet tall. Some plants evolved to be drought-resistant, fire-resistant or browse-resistant trees. Tropical grassland animals (which do not all occur in the same area) include giraffes, zebras, buffaloes, kangaroos, mice, moles, gophers, ground squirrels, snakes, worms, termites, beetles, lions, leopards, hyenas, and elephants. Herbivores like: eland, impalas, gazelles oryx, gerenuk and kudu. Buffalo, wildebeest, plains zebra, rhinos, giraffes, elephants and warthogs are part of the African savanna. Some carnivores that live in the grasslands include: lions, leopards, cheetahs, jackals, wild dogs and hyenas. Termites are also a great part of the tropical grasslands world. Since grasslands are an open space biome, it allows animals to reach top speed when running like cheetahs and gazelles. Over time speed has become a great factor and part of the species in the tropical grasslands.Lacking trees, rocks or other structures to hide behind, grassland animals have often evolved highly effective camouflage, which allows them to hide while in plain sight.


The Grasslands

Dominant Vegetation

Grasses are the most common vegetation in the grassland biome. These grasses can grow up to 3-6ft in height at maturity. There not many trees in the biome since there is very little rain. Wildfires also play a factor in the amount of trees and vegetation too. The soil is very rich but since rain rarely falls in the area they water is soaked up quickly. Because the savanna supports such a large number of species competing for living space, usually only one or a few kinds of grass are more successful than the others in a particular area. Some specific plants include, Acacia Senegal, Baobab, Bermuda Grass, Candelabra Tree, Elephant Grass.

Elements Affecting Grasslands

An abiotic factor that affects grasslands is climate. It is one of the most crucial aboitic factors that shape the ecosystem and includes rainfall, temperature, wind flow, ground moisture etc. Climate can also cause some natural disturbances like floods during heavy rains or scorching conditions in high summers. All these factors to the grassland ecosystem. Another factor that can affect animals in the tropical grassland is hunters kill animals for sport and collect their skins and other parts of their bodies for them to sell. Animals like the Elephant are endangered because of humans hunting them down for many decades for their ivory tusks.
