How does climate affect vegetation in South Africa?
The vegetation growth over these regions may be due to increasing carbon dioxide sequestered by the vegetation (e.g. tropical forest) which enhances their growth. It could also be because of the likely increase in summer rainfall over east coasts of South Africa (Mackellar et al., 2014).
How does climate affect the vegetation in Africa?
Plant life is influenced by the amount of rainfall. … In some areas, like the Sahel zone, there are large differences in rainfall every year. In the last decades droughts have caused hunger and starvation in many part of the Sahel and Ethiopia.
Which South African biome has plants that are adapted to periodic fires?
Fynbos system in South Africa
Periodic fires are a natural phenomenon in Fynbos vegetation (Kruger and Bigalke, 1984; Brown, 1993a), with a frequency of 5–40 years (Kruger and Bigalke, 1984).
What biomes are controlled by fire?
Many ecosystems, particularly prairie, savanna, chaparral and coniferous forests, have evolved with fire as an essential contributor to habitat vitality and renewal.
How does climate affect vegetation?
Vegetation can affect climate and weather patterns due to the release of water vapor during photosynthesis. … The release of vapor into the air alters the surface energy fluxes and leads to potential cloud formation.
What is Africa’s vegetation?
Africa’s vegetation consists of grasslands, rain forests, and a wide variety of other plant life.
What is the vegetation in South Africa?
Natural vegetation in South Africa varies from savanna through grassland with fewer trees to scrub and scattered bush and drier western areas. Because of dry summers Western Cape has a distinct vegetation of grasses, shrubs, and trees. The eastern coast has a more tropical plant life.
What type of vegetation covers most of Africa?
Savannas, or grasslands, cover almost half of Africa, more than 13 million square kilometers (5 million square miles). These grasslands make up most of central Africa, beginning south of the Sahara and the Sahel and ending north of the continents southern tip.
What is the relationship between climate vegetation and fauna?
Climate is the major determinant of vegetation. Plants in turn exert some degree of influence on climate. Both climate and vegetation profoundly affect soil development and the animals that live in an area.
What is exclusively found in South African fynbos vegetation?
The fynbos is home to many unique and endemic animals, with 7 species of endemic bird and an unknown number of endemic reptiles, amphibians, and arthropods. The 7 avian endemics include the Cape rockjumper, Cape sugarbird, Victorin’s warbler, Orange-breasted sunbird, Protea canary, Cape siskin, and Fynbos buttonquail.
What is the climate of grassland biome in South Africa?
South Africa is subtropical, with temperatures modified by altitude. The interior, where the bulk of grasslands are found, is semi -arid to arid, with rainfall decreasing westwards. The south and southwest have winter rainfall; the eastern Cape is bimodal; and Kwa-Zulu Natal has summer rainfall.
What type of vegetation is the thicket biome Characterised by?
4. Thicket. Lining the mountain slopes and cool valleys, this rocky biome is characterised by its dense vegetation and presence of nutrient rich plants such as Spekboom.
What are the causes of fire ecology?
Causes of fire
Some of the fires caused by accidents and negligent acts are through unattended campfires, sparks, irresponsibly discarded cigarettes and burning debris. The remaining 10% of fires are caused by lightning strikes, which are especially prevalent in the Western United States and Alaska.
What plants depend on fire?
Some examples include: white fir, vine maple, western red cedar, and western hemlock. Just as some plant species need fire to regenerate, some plant communities require periodic fire to maintain their health, or even their existence. Grassland and oak savannah are two such fire-dependent plant communities.
What is forest fire ecology?
USDA Forest Service photo. Fire ecology explores the interactions between fire and the surrounding environment, including both living and nonliving things. Fire ecologists recognize that fire is a natural process that is often integral to the life history of plants and animals in the ecosystem.
