narrow leaf cotton bush

Cotton Bush is costing you and your farm!

Declared weeds are targeted as they reduce productivity on prime farm land and cotton bush is the declared weed firmly in the sights of the Peel-Harvey Biosecurity Group.

The Peel-Harvey Biosecurity Group was initiated from Community concern over the impact that cotton bush is having on agriculture and the environment. This Community based organisation is dedicated to working with landholders, agencies, industry and local government to highlight areas of concern and to assist all types of landholders to manage infestations through a coordinated approach.

The group also understand that property owners can be overwhelmed with starting a plan to control weeds on their property, especially if there is a heavy infestation or they are affected by weeds on adjoining land. The group are hosting four workshops that will help participants create a weed management plan for their property. Each workshop is tailored with a regional focus with an informative presentation and an opportunity for landholders to work with experienced weed controllers to create a workable easy to follow management plan for their property.

The Peel-Harvey Biosecurity Group will also be handing out chemical vouchers for new members of the group and participants of the workshops to aid them in their control of cotton bush.

Tyre spikes hinder DAFWA v Water Hyacinth battle

Picture of Water Hyacinth

DAFWA has caught the sharp end of the stick in its hunt for water hyacinth (Eichhornia crassipes) in the Birega drain and Serpentine River lately. Tyre spikes have been planted along access roads adjacent to these water systems and have made surveying the spread of the C2 weed almost impossible. Darryl Stewart , Biosecurity Officer for DAFWA, asks that all community members call in sightings of Water Hyacinth in their local area so that management can be swift and effective.

Water hyacinth is native to the Amazon basin in South America and was brought to Australia in the 1890s as an ornamental plant. Under the National Weeds Strategy, Water hyacinth is one of 32 introduced plants that have been identified as Weeds of National Significance (WONS), these weeds are regarded as the worst weeds in Australia because of their invasiveness, potential for spread, and economic and environmental impacts.

Popular as an aquarium plant water hyacinth is still being sold at weekend boot markets, aquarium shop outlets, nurseries and online on sites such as gumtree. Those selling water hyacinth to the public can face prosecution in some cases. Water weeds such as water hyacinth are often dumped along with unwanted aquarium fish into local water ways where it has the capacity to block irrigation channels and rivers, restrict livestock access to water, destroy natural wetlands, change the temperature, pH and oxygen levels of water and restrict recreational use of waterways. Due to its high level of invasiveness DAFWA would like all community member to keep an eye out for water hyacinth and keep access roads clear for future surveillance. If you see some report it to Darryl Stewart, DAFWA Biosecurity Officer on (08) 9363 4039.
