savanna, also spelled savannah, vegetation type that grows under hot, seasonally dry climatic conditions and is characterized by an open tree canopy (i.e., scattered trees) above a continuous tall grass understory (the vegetation layer between the forest canopy and the ground).

What are 3 characteristics of the savanna?
Savanna vegetation includes scrub , grasses and occasional trees, which grow near water holes , seasonal rivers or aquifers . Plants and animals have to adapt to the long dry periods. Many plants are xerophytic - for example, the acacia tree with its small, waxy leaves and thorns.
What is the environment like in the savanna?
The climate is usually warm and temperatures range from 68° to 86°F (20 to 30°C). Savannas exist in areas where there is a 6 - 8 month wet summer season, and a 4 - 6 month dry winter season. The annual rainfall is from 10 - 30 inches (25 - 75 cm) per year.
What characteristic do the tropical savanna and tropical rain forest climates share?
The tropical savanna climate has alternating dry and wet seasons, hence its name. It shares some similar characteristics with the tropical monsoon climate, but it receives less annual rainfall as compared to the tropical monsoon climate.
What characteristics do savannas share with prairies?
Prairies and savannas often occur alongside each other, one merging gradually with the next. The ground cover of both prairies and savannas is dominated by native warm-season grasses, such as big and little bluestem, Indian grass, and sideoats grama. Warm-season grasses are beautifully adapted to Missouri's climate.
What is the physical environment and soil composition in the savanna?
The savannas are grasslands that have several months of dryness, followed by a rainy season. A majority of the soils in this area are Alfisols and Ultisols. These soils are very old and low in fertility, but since there is a dry season, more of the nutrients can stay in place.
How does climate affect the savanna?
Climate change to have contrasting effects
Grass coverage will decrease in dry savannas, increasing coverage of shrubs and trees in previously open grasslands and rangelands - enhancing a phenomena increasingly observed today. Conversely, in wetter savannas, climate change may limit tree growth.
What is the climate of the savanna in Africa?
The savanna climate has a temperature range of 68° to 86° F (20° - 30° C). In the winter, it is usually about 68° to 78° F (20° - 25° C). In the summer the temperature ranges from 78° to 86° F (25° - 30° C). In a Savanna the temperature does not change a lot.
How would you describe the savanna biome?
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.
What is a fun fact about the savanna?
Interesting Savanna Biome Facts:
Because of the availability of grass in the savanna, there are many grazing animals who take advantage of this abundant food supply. The savanna biome is rich with herbivores such as elephants, zebras, gazelles, and buffalo. The largest part of the savanna biome is located in Africa.
What are the characteristics of grasslands shrublands and savanna ecosystem?
The Tropical and Subtropical Grasslands, Savannas, and Shrublands are characterized by rainfall levels between 90-150 centimetres per year. However, there may be great variability in soil moisture throughout the year. Grasses dominate the species composition of these ecoregions, although scattered trees may be common.
What other type of biome does a savanna share characteristics with?
These can be split further. For example, savanna grassland and temperate grassland are the two main types of grassland biomes. Savanna biomes are found between tropical rainforest and desert biomes. They share certain characteristics of both.
What is the biodiversity of the savanna?
Savannas cover at least 40 percent of the global tropics and support a fifth of the world's population, thus efforts to better understand biodiversity and ecosystem functioning in these systems are essential for climate change mitigation and effective policy formulation.
Do savannas have good soil?
Edaphic savanna conditions are determined by their soil, rather than climatic conditions. The soil is not as dependent on wild fires to restore the nutrient content. ... As a result, the soil is generally very dry and porous most of the year, contributing to natural fires, which burn the grass and vegetation in the area.
What type of water is in the savanna?
Water. Water is necessary for all life, and the savanna grasslands are typically dry with little rain over the course of the year. Major rivers provide much of the water for the people of the savanna, and large population centers typically develop in these areas.
