The weed grows perennially to about 1-2m high and sometimes forms canopies growing up to 10m high, wich have covered the undergrowth preventing them from accessing sunlight. Te bush sprawls and covers a large area with branched stems which are woody. Te shallow roots of the plants making it difficult to pull as the fibrous root system do not allow it 2015). Wen slashed, i sprouts and flowers producing more seeds spreading to the other areas and increasing the area under coverage. Te invasive nature of the bush poses lot of difficulties for the authorities tasked with controlling its spread.
Te bush has an extensive root system and is very hard to control its spread than the other plants such as the bone seed. Te flowers appear dustered at the on the branches’ ends and are yellow in colour, ad 20mm in diameter. Te bush produces tiny berries with a green fleshy skin that turns brown once they mature, wich attract birds that feed on them facilitating dispersal in other areas. Te single seed contained in the fruit egg-shaped and 5-7mm long and black in colour once it dries.
Te germination of the seeds is throughout the year although in autumn it is more due to the favourable conditions making it quite difficult for the authorities to eliminate it. Te growth is very fast with some plants flowering within the first year after germination although some plants can take as long as 18 months or 3 years before flowering and lowers throughout the year. Pants growing in the North flower earlier than the ones growing in the coast of New South Wales making the infestation of the plant difficult to control.
Ech Bitou plant produces about 50, 000 seeds in a year and the dispersal are by animals and birds, wich lead to the spread of the bush in several areas 2015). Brds are the main means of seed dispersal as they eat the fruit and disperse the seeds several kilometres the other animals that feed on the fruits are rabbits and foxes, wich pass the seeds in their stool facilitating seed dispersal (Schoeman, Bckley, Cerry, & Steadman, 2010).
Te other means of dispersal are human activities, wter, ad windblown sand. Btou Bush is spreading very fast and further into the forests and woodlands in the coastal strip as the recent mapping has shown that infestations...
