Hygiene – prevent the spread of weeds/seeds

Weeds are plants that invade areas where they do not belong.  They destroy original ecosystems, damage health and restrict optimum usage of land. They often spread from backyards when people dump garden clippings onto road reserves, vacant land or near bushland.  Birds and animals carry them on their fur so they need to be inhibited as much as possible. Fragments of weeds – bulbs, roots, tubers, seeds, spores – more adapted to the artificially enriched soils of urban areas than native plants, sprout easily, and outcompete the original ecosystem. Native bushland is smothered. When the weeds decay they increase soil and water nutrient load. When they die they build up a fuel load and there is greater threat from fire in many cases. They threaten the very existence of wildlife that is already endangered, plant and animal.  Plant pathogens (diseases) can also destroy native ecosystems.  To find out more about plant pathogens click here.

HOW INVASIVE PLANTS INVADE BUSHLAND

HOW TO PREVENT THIS

Growing a plant that is invasive

Replace an invasive plant with one that belongs in your area and that is food and shelter for the native life forms of any local bush. Your council will have a list of these indigenous native plants.

Blown by wind

Where you see weed seed blown by wind, alert the person responsible for managing the land to the problem. Do not keep an invasive plant with windblown seed. It will travel far and wide.

Carried by animals on fur/feathers

The only way to stop this is to not permit the weed to exist. Advise anyone of an invasive plant which has seeds that can stick to creatures or clothes to get rid of it, or stop it seeding by frequent mowing.

Carried by water

Never leave a weed pile near a creek edge or within a flood zone. Sudden storms will wash it downstream where it will spread.

Sprouting from sections of the plant (vegetative spread)

Never dump any garden waste in or near bushland. Compost it so that the heat of the process ‘cooks’ the part that reproduces. For some weeds this is very difficult and it is better that they go to landfill. Don’t put weeds like that in the green waste bin or facility from which it could spread to other gardens or bush reserves.

On vehicles, machinery, mud or mulch

Clean gardening equipment where you have used it on weeds to prevent transport of seed beyond. Wash down your car in an area where you can catch the weed seed if you have driven through any. Beware of mud on machinery. Be careful of mulch that you use…it could contain weed seed propagules. Report any weed seed in mulch to supplier, and complain.

Not enough people controlling weeds the correct way

JOIN your local bushcare group and help clean up the public reserves and bushland areas in your neighbourhood. Contact your local Council to find a bushcare group. Most councils will have a bushcare officer…LINK TO BUSHCARE GROUPS




To further protect the natural environment:

Don’t let cats and dogs prey on native birds and animals. Place a ringing bell on your pet’s collar and keep it inside or in a special enclosure.

Most native trees and bushland are protected. Even a single tree plays an important role in the natural ecosystem in your area and can keep endangered creatures alive. Try to keep as many native trees as possible.

Dumping of rubbish and building materials is illegal and destroys bushland, creeks and stormwater channels as chemicals in manufactured products break down and are released into the environment. The cumulative impact of the many chemicals damages the delicate skin and nervous systems of small creatures, and plastics and nylons strangle wildlife. Via the food change these chemicals threaten the metabolism of all wildlife. Report all dumping to your local council as soon as you see it.
