The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses.. Savannas maintain an open canopy despite a high tree density. A post-emergence application of 100 kg/ha of urea (= 46 kg/ha N) in pure stands will stimulate more rapid stand development. It is also finer leaved and more stoloniferous. Seedhead:   Mostly a single (sometimes double) circle of radiating light, greenish brown (ripening to darker brown) branches 4 - 15cm long. There are also lots of trees scattered about the savanna. Gramineae (South Australia) Poaceae (Queensland, New South Wales, the ACT, Victoria, Tasmania, Western Australia and the Northern Territory) Tolerates heavy grazing 7.

Some grass species in these habitats include red oat grass (Themeda triandra) and Rhodes grass (Chloris gayana) in tropical savannas, and purple needlegrass (Nassella pulchra) and galleta in temperate areas. While it can be successful at lower annual averages (as low as 500mm in NSW), it is not suited to areas of very high rainfall (more than 1,800 mm/yr). It is a useful forage for pasture and hay, drought-resistant and very productive, of high quality when young. Denotes that this variety is protected by Plant Breeder's Rights Australia. Rhodes grass (Chloris gayana) grows on the savanna where it reaches up to 5 feet in height. Some learn to eat around spines or thick covering. Callideis later flowering than Katambora, is less cold-tolerant and needs a higher rainfall than Pioneer or Katamb… Thus, every plant and animal in the savanna is important for the savanna to survive. Production levels decline without a vigorous legume or the use of fertiliser nitrogen. It has an umbrella shape, with branches and leaves high off the ground … With a defense like that, the tree has little to fear. And then, of course, there is a prediction by herbivores.

Chloris gayana is a robust, strongly stoloniferous grass native to Africa that has been extensively introduced as forage across tropical and subtropical regions. It is best in soils with pH between about 5.5 and 7.5, but will grow down to pH 4.5 (if available aluminium and manganese levels are low) and up to 10. When grazed upon, the acacia tree sends a bad taste to its leaves so that grazers only get a few mouthfuls before the leaves start tasting terrible.

The umbrella-shaped acacia tree, which grows tall and flowers at the top where only giraffes can reach, is seen throughout the savanna. It has moderate frost tolerance, with 'Katambora' and 'Pioneer' types being less affected by frost than is 'Callide'. The branches all grow from one trunk, and look like little cactuses that grow near the top, giving it the shape of a candelabra. It is usually sown in areas receiving an average annual rainfall of 700 - 1,200mm, and is well-suited to irrigation. However, the acacia tree has an even more powerful defense. Moser, B.L.
