Write 12 pages thesis on the topic weed impact on biodiversity. The Bush threatens the vegetation on the coastal dune on the East Coast (Downey, Cherry, Winkler & Hamilton, 2012). The Bush competes with the other plants and in several cases replaces them altering the natural habitat for birds and animals. The bush grows in many habitats and spreads very fast posing a threat to the Australian ecosystem. The Bitou Bush poses threats to the environment and biosecurity in the New South Wales Coastline.
Bitou Bush was noted in Australia in 1908 near Newcastle in New South Wales when ships dumped ballast from South Africa. The plant was planted to re-vegetate the coastal areas from 1946 to 1968 after sand mining that left the area bare (Native Plants Species at Risk from Bitou Bush Invasion, 2015).
. The plant was also used for dune stabilization on the coast by providing vegetation cover to the bare environments. Bitou Bush invasion stands at 80 percent in the NS coastline and other areas. The plant now forms the dominant vegetation cover in the New South Wales coastline where it has invaded many of the native plant species such as the beach-dune vegetation and the coastal woodlands. The invasion of the plant in many areas was declared a threat to the NSW Threatened Species Conservation Act (TSC Act) as it poses a threat to more than 30 plant species (Native Plants Species at Risk from Bitou Bush Invasion, 2015).
The weed grows perennially to about 1-2m high and sometimes forms canopies growing up to 10m high, which have covered the undergrowth preventing them from accessing sunlight. The bush sprawls and covers a large area with branched stems which are woody. The shallow roots of the plants making it difficult to pull as the fibrous root system does not allow it (Native Plants Species at Risk from Bitou Bush Invasion, 2015). When slashed, it sprouts and flowers producing more seeds.
