SWEETWATER CREEK NATURE RESERVE
Frankston, Victoria, Australia
To encourage the community to sustain, develop and enjoy the natural beauty and ecology of Sweetwater Creek Nature Reserve
Much of our regeneration work in the reserve involves the removal of weeds to allow the indigenous plants to re-emerge.
Shown here are some of our most invasive and hard-to-eradicate weeds.
We approach weed eradication in different ways;
The Bradley method of bush regeneration, for example, involves the gradual and systematic removal of weeds, starting from a clear area and working towards the most heavily infested.
Using this method, the disturbed soil is covered with leaf litter and observed for regrowth, whether of weeds or indigenous plants. To avoid damage, only a small team works together on the site. Wandering Jew, seedlings of asparagus fern and sweet pittosporum are typical targets.
A concerted attack may be made by a larger group of volunteers over several weeks on areas badly infested by larger weeds, for example, cape ivy and morning glory. These weeds threaten to strangle quite large trees and shrubs. Removal of these weeds may be followed up with plantings of indigenous shrubs and grasses
Another approach is to burn an area where there is a monoculture of non-indigenous trees, for example,coastal tea tree.The results of a burn are remarkable as the original indigenous plants begin to emerge over the following year. Frankston City Rangers always manage a burn, but ASC Inc. volunteers follow up in time with careful weeding.
