Review of Invasive Weed Programs In Australia
Invasive weeds “sensu Kolar and Lodge, 2001” are serious issue and big problem to the ecosystem throughout the world “Mack et al., 2000”. Habitually, invasive weeds are larger in size and have high densities as compared to native populations and this is thought that they affect the environment at high rate because of their higher densities and larger size “Torchin et al., 2003 cited by Wright, 2005”.
In the high area of conservation value the weeds are the major threat to biodiversity. Unluckily, individuals may be involuntarily dispersing and introducing seeds of weeds on their clothing when they visit these areas. Data shows that seeds of weeds can translocate with other places with the clothing. A total of 287 of the types are listed as foreigners in one or more countries in Europe, 211 are naturalized outlandish plants in Australia, 156 are invasive kinds/harmful weeds in North America, 97 are foreign species in India, 33 are disturbing species in China and 5 are confirmed weeds/intruders in South Africa “Ansong & Pickering, 2014”. Clothing of hikers can carry the seeds maximum distance of 13 km, but the people travel in buses, cars, train, planes and boats can carry the seeds much long distances “Ansong & Pickering, 2014”. The type of material the clothing is made from, the type of clothing, the number and location of the seeds on plants, seed traits such as adhesive and attachment structures are the factors that affect this type of seed dispersal. Areas which are specific for tourists using is increasing including popular protected areas, in remote regions may be great risk of biological attacks by weeds with seeds carried on clothing “Ansong & Pickering, 2014”.
AIMS OF THE PROJECT
The basic aim of the project is to assist the native fauna which is under threat because of invasive weeds

• Regulations National, State and Local acts and rules
• Discuss the 2 Species at Bulwer that are threatening National eg. Asparagus Fern, Pricky Pear
• Methods of Control of 2 main weed threats
• Weedicide vs physical removal include Advantages and Disadvantages
• Solutions to this biosecurity issue
