Tropical savanna biomes can be found in Australia, vast expanses in Africa as well as in India and sections of South America. Tropical savannas lie within the tropics between the latitudes of 23.5 North and 23.5 degrees South. Producers in the tropical savannas are generally photosynthetic plants. Producers provide foodstuffs for all other biotic organisms in tropical savannas.
Originally from the African grasslands, this species can be found anywhere between 45 degrees North and 45 degrees South. Classified as a weed, it is hardy and thrives in disturbed areas. Measuring between 4 inches to a foot tall, Bermuda grass has an extensive root system that makes it drought tolerant and capable of fast reproduction. The blades measure between 1 and 4 inches long and are a grayish-green color. Grazing animals such as cows and sheep eat Bermuda grass.
This tree is a variety of eucalyptus that can reach heights of 150 feet. The long, branch-free trunk can measure 9 feet in diameter. The leaves vary between 8 and 13 centimeters in length and are various shades of green. It flowers biannually and provides food for bees, other insects and birds. It is widely found over the Australian Savanna.
The river bushwillow is one of 500 varieties of related trees. Found only in the African Savanna, this tree grows only between 5 and 15 degrees North latitude and 15 and 50 degrees East longitude. Countries within this restricted geographical area include: Madagascar, Senegal, and Ethiopia. Growing to over 30 feet tall and along riverbanks, this tree is a food source for giraffes, who feed upon its leaves.
The Jackelberry Tree is widespread in the African tropical grasslands. The Jackelberry has a gray trunk that leads to a dark green canopy of elliptical-shape leaves. This tree is often found on top of termite mounds. A symbiotic relationship exists with the termites and the Jackelberry Tree. The termites provide suitable soil and moisture for the tree, which protects the termite mound against predators. The Jackelberry can often obtain heights of 15 feet. Yellowish oval-shape fruit of the Jackelberry provides sustenance for many savanna dwellers, including wart hogs and parrots.
This red and green plant produces red flowers that can grow to 13 centimeters long. The stem can reach heights of 3 feet. Sandy or gravelly soils that have been burnt provide the ideal habitat. It lives for two years and is named for the red flowers that resemble "kangaroo paws." Found only in Australia, this plant provides nectar for wattlebirds.
