Blue Gum High Forest

In Iona Creek Reserve, weeds were located around the grassy area. This is a major issue, not just because weeds are an invasive and fast growing species, but also because there are endangered plants located on the site. The Blue Gum High Forest is the main endangered species on the site. This forest sheltered the Sydney region before European settlement, and is now limited to small bushland along a small range of suburbs in Sydney. The Blue Gum Forest is one of six main indigenous communities of Sydney and listed as critically endangered under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act), and an endangered ecological community in NSW under the NSW Threatened Species Conservation Act 1995 . It is therefore imperative that weeds are removed in the site, in order to preserve the endangered species and not threaten their survival.

Using herbicides would be the most suitable way to remove the weeds on the site, as they are the most cost-effective and long-term control use. After the herbicide is used, a soil acting residual should be used to most effectively remove all weeds, and ensure they stay absent.

Pollution can be seen not just in the Reserve, but also in areas surrounding it. This is due to …show more content…
Additionally, bioremediation is the ability to use naturally occurring microbes to concentrate and digest contaminants present in water. These organisms include bacteria, fungi and algae, and they are able to convert the toxic species to water and other gases, such as carbon dioxide. Phytoremediation is additionally helpful in removing contaminated soil from water. It is cost effective and simple to put into practice. Bioremediation and phytoremediation are environmentally adaptable and cost-effective, and since Iona Creek is not large, it makes it a suitable method for pollution
