savanna veg adaptions
Adaptations of Savanna vegetation.

Savanna vegetation must adapt to survive. Many problems must be overcome, such as lack of water, very seasonal rainfall, poor soil quality, grazing animals, very high temperatures and fire.

1. Define the following terms:
Xerophytic = A plant adapted to living in a dry arid habitat; a desert plant

Pyrophytic = plants adapted to tolerate fire

Deciduous = Loss of leaves seasonally

Perennial = lives more than 2 years

Dormant = A condition of significantly reduced activity with very less or no growth. All physiological activities, like photosynthesis, are minimal or non-existent.

2. Research specific adaptations/plants which are typical of the Savanna. Your notes should clearly outline what the adaptation is, why it is needed, and the name of the plant species. Aim to get a range of adaptations for both grasses and trees. Arranging your notes in a table is the best method:

Name of species
Adaptation
Reason for adaptation
Notes (location, features etc)
Baobab tree

Thick, corky bark which stores water and is fire resistant.
Shiny bark.
Stems have ‘U’ shaped channels to collect and store rain and dew
(Adapted to fire & drought)
In the wet months water is stored in its thick, corky, fire-resistant trunk for the nine dry months ahead. Survives regular fires and withstands drought. Reflects light and heat
Located in the savannas of Africa and India and found mostly around the equator.
Acacia tree
It can survive drought conditions. Also fire resistant. The acacia tree has developed very useful physical and behavioural adaptations to discourage animals from eating its leaves. It developed long, sharp thorns and a symbiotic relationship with stinging ants
(Adapted to drought and fire & predators)
It survives drought because it has developed long tap roots that can reach deep, ground water sources.

Bermbuda grass

It’s a form of creeping grass and has a deep root system, which can grow up to 60

    The dry wallum is a harsh environment that is battered by the sun and wind every day and with a base of porous sand; water availability is very scarce and must be conserved. The abiotic factors in the dry wallum are that the area is exposed to high amounts of sunlight which causes a loss of water in the leaves through transpiration. Since the wallum is so dry and hot; bush fires play a major cycle in the dry wallum which the trees have adapted to cope with. The roots of the plant and tree species have to cope with the leeching of nutrients because of the high porosity sand in the dry wallum.…

    Tropical savannas are related to the tropical wet and dry climate type. Savannas grow in the regions where the climax community should be some form of seasonal forest or woodland, but changed conditions or bothers prevent the setting up of those types of trees with the same climax community. The word savanna directly means plains.…

    In this report we will be exploring Grasslands, define abiotic and biotic, we will see where Grassland I located and see an example. We will describe the structure of Grassland: listing both the abiotic and biotic components of Grassland, we will be describing the function of the ecosystem. How do the abiotic and the biotic components interact in biochemical cycles? Describe both the carbon and nitrogen cycles, describe the disturbance and recovery: describe one natural and one human caused disturbance to the Grassland. Give an explanation of the damages to the Grassland, including how the abiotic and biotic characteristics of the Grassland have changed; we will be giving explanation of how Grassland recovers naturally.…

    Deserts are also found in areas where rainfall is less than 50 cm a year. However, with a little rainfall, most of the deserts have a considerable amount of specialized vegetation and vertebrate and invertebrate animals as well. And there are only a few large mammals in the deserts because they are not capable of storing sufficient water or withstanding the blistering heat. In the variety of the deserts, plants have had to develop different ways of capturing water in the roots, stems, leaves or fruit in order to survive in their habitat. There are short grasses, sagebrush, creosote bushes and cacti can be found in nearly all deserts. About animals, in order to survive, they try to stay in…

    A savanna is a rolling grassland scattered with shrubs and isolated trees. It can be found between a tropical rainforest and desert biome. Not enough rain falls on a savanna to support forests. Savannas are known as tropical grasslands. They are found in a wide band on either side of the equator on the edges of tropical rainforests. They are located in Africa, South America, India, and Australia .Some animals that habitat here are wildebeest warthog elephants zebras and rhinos.…

    Tropical savannas or grasslands are associated with the tropical wet and dry climate type. A tropical wet and dry climate predominates in areas covered by savanna growth. Average monthly temperatures are at or above 64° F. Although these areas are overall very dry, they do have a season of heavy rain. Annual rainfall is from 20-50 inches per year. It is crucial that the rainfall is concentrated in six or eight months of the year, followed by a long period of drought when fires can occur. If the rain were well distributed throughout the year, many such areas would become tropical forest.…

    Australia has some of the oldest and largest rainforest in the world. It supports a rich and various life. What makes animals and plants suited to this particular environment or what kinds of features that an organism posse which they genetically inherited from their parents that enable them to survive the current environment and to keep reproducing? Adaptations. Adaptations are the result of evolution which is a change in a species over long periods of time. Adaptations usually happens due to the presence of mutation. Some mutations can bring an animal or plant the advantages so that they can survive better than others in the species without the mutation. All organisms have adaptations that help them survive and reproduce.…

    Due to the scarce rain and very dry weather, deserts have unique vegetation patterns. Depending on the type of desert and the geographical location, common desert plants include cacti, sagebrush, creosote bushes, shrubs, and short grasses. Agricultural plants are rare, because they are only found where rivers and streams take place, which is very uncommon in most deserts. The vegetation has adapted to survive in the desert biome by using several distinct features to prevent water loss, attacks from predators, and the harsh weather conditions. Many plants found in the desert are succulents, meaning that they have thick, large stems to hold and contain water. They also have leaves with a waxy coating that helps to keep water in. Since the desert contains a lot of browsing animals hungry for food, desert vegetation, such as shrubs, are equipped with sharp spear-like spikes that provide defense against prowling predators lurking for the plant’s juicy flesh.…

    Arabic tree, babul, Egyptian thorn, Sant tree, Al-sant or prickly acacia; called thorn mimosa in Australia; lekkerruikpeul or scented thorn in South Africa) is a species of Acacia (wattle) native to Africa and the Indian subcontinent. It acts as a biological control agent for herbivores. It is found in the central belt of Indian subcontinent and Australia. This plant has been used as a source of pulpwood, timber, fodder and gum. The whole parts of the plant used for medicinal purposes like barks act as astringent which found to be useful in the treatment of dysentery, diarrhea, leprosy and smallpox. This plant also shows antioxidant activity. The leguminous trees are one of the most significant components of forest vegetation due to their economic and ecological importance. However, the regeneration rate of this plant in natural surroundings is quite low. In general, the woody plants are difficult to regenerate under in vitro conditions but some success was achieved in a few leguminous tree species except Acacia nilotica.…
