Removal

Once established, it has the potential to completely smother and replace indigenous ground cover vegetation. It is a very persistent weed and may take extensive time and effort to eradicate.

Remove small and scattered plants first and then target outer edges of larger infestations. Best removed prior to seed when plants are fully grown and parent bulb exhausted.

Seeds from the plant are generally dispersed by wind, with most seeds only dropping a few metres from the parent plant.

Seeds can also be spread by livestock, birds and flood.

Once established, the weed shades out most pasture species as well as drawing moisture and nutrients from the soil.

The plant is reported to cause contact dermatitis in some people.

Blackberry fruit are eaten by birds, foxes and other mammals which distribute seeds over wide areas.

Seeds are transported by water along creeks, drains and rivers. Movement of contaminated soil and cultivation also spread blackberry.

Infestations increase in size via the formation of daughter plants at the end of canes, up to 6 m from the crown.

It can provide harbour and a food source for pest species, as well as serve to outcompete and eliminate other vegetation by excluding light from the soil surface. Blackberry can restrict access to and along watercourses which may affect recreational activities. They are also a large fire hazard because of all the dead canes they leave behind.

Physical removal and mulching.

Boneseed is spread by seed only.

Germination is promoted by fire, soil disturbance, weathering and ingestion of seeds by animals. Most seed is dispersed by animals such as foxes and birds or through water.

Seeds may also be spread in soil stuck to vehicles and equipment.

Dense infestations of boneseed can virtually eliminate native understorey species and reduce the regeneration abilities of native trees and shrubs.

Gorse reproduces by seed. Its seeds are hard and need some damage or scarification to the coat before they will germinate.

This damage can be caused by fire, soil disturbance, insects, changes in soil moisture, being scraped by floodwaters or passing through an animal's stomach.

Gorse is spread by seed ejection, transportation of soil, sand or gravel, livestock, birds, ants and water.

Gorse competes with young trees and shrubs and hinders the growth of native understorey species. A longterm effect of the plant's presence is that the soil becomes more acidic and loses nutrients. Gorse is a major weed of agriculture invading all pasture types and significantly reducing grazing capacity. It is also highly flammable and a significant fire hazard.

Application of a registered herbicide, cultivation, physical removal and mulching

Spread by contaminated machinery, vehicles, animals, agricultural produce, mud and other animals.

Forms dense thickets that seriously impede movement. Birds, possums and wallaroos are known to eat the fruit. Provides habitat and food for smaller native animals but also provides a food source to some pests (birds and foxes).

Seedlings can be manually removed but larger plants may need thorough removal. Chemical sprays may work but require frequent treatment.

Seeds can be spread by animals, machinery, water, agricultural produce including hay and silage, gravel, soil extraction and to a limited extent by wind.

Hemlock contains five toxic alkaloids which vary in concentration due to climatic conditions. The fruit, vegetative parts and roots are all poisonous to humans and stock.

Regular spraying with registered herbicides has proved to be successful, but may damage the other indigenous animals within the area.

Serrated Tussock is a prolific seeder with 90 per cent of the plant selfpollinating. Seed heads of the plant are carried along the ground and in the air and may be blown considerable distances; up to several kilometres.

The seeds of the weed are also dispersed by moving water, mud, in hay and fodder, on machinery and equipment, coats of livestock and in the droppings of animals.

Serrated tussock takes only seven years from establishment to dominate a pasture or native grassland, threatening rare native plant species and resulting in a loss of flora biodiversity.

Serrated tussock is a serious weed of pasture with significant impacts on carrying capacity and a reduction in agricultural return.

Fennel Application of a registered herbicide and physical removal.

Changes in land use practices and spread prevention

Boneseed

Slender Thistle

Hawthorn

St John’s Wort

Chipping or hoeing physically removes the serrated tussock plant from the ground. It is a great method wher infestation are scattered or light.

Once removed shake soil from the roots to remove any remaining soil exposing the roots and allowing them to dry out.

Treatment requires frequent follow ups.

African boxthorn reproduces exclusively by seed which is commonly eaten by birds, seed is viable when excreted.

These plants are often found near places where birds have perched such as trees, poles and powerlines. It was widely planted as a hedge plant before its weedy potential was realized. Spread also occurs from contaminated produce and materials.

If untreated, African boxthorn grows to a great size and dense infestations outcompete native plants. It invades watercourses denying animals access to water. It also provides harbour for pest animals such as rabbits and foxes.

African boxthorns also provide a breeding place for pest insects such as fruit fly, dried fruit beetle, tomato fly and the house fly. It is known to be toxic to humans.

Application of a registered herbicide and physical removal.

Cultivation of the soil in which young African boxthorn plants grow may also support its management.

English broom is spread only by seed. Most seeds fall within 1 m of the parent plant but seed pods can explode in the heat of summer and eject seeds up to 4.5 m away from the parent.

Seeds in mud can attach to vehicles, machinery, footwear and animals.

Floodwaters and animals can also contribute to spread. English broom flowers prolifically, but only a small proportion of the flowers develop into fruits.

It has the ability to become the dominant species and smother native vegetation, particularly after fire events, due to strong seedling recruitment. The weed also out competes poor or degraded pasture and reduces agricultural production, while providing harbour for a range of pest animals.

Application of a registered herbicide and physical removal.

Changes in land use practices and spread prevention may also support English broom management.

Reproducing by seed, from the crown and pieces of crown and root.

Crown and root dragged by equipment and machinery. Seeds spread by vehicles, machinery, animals, clothing, water and wind.

Dense infestations may restrict access to waterways. Not a serious weed of pasture or cropping.

Physical removal requires the full removal of all roots. A number of herbicides are also registered for the removal of Fennel.

Flax-leaved broom is spread by seeds that are ejected from its pods.

Spread also occurs when seeds contaminate vehicles, machinery, produce, mud and soil.

It has the ability to crowd out smaller shrubs and groundflora species, mainly lower and mid-storey plants, and eventually impact the food sources of native fauna. A haven for pest animals.

Application of a registered herbicide and physical removal.

Changes in land use practices and spread prevention may also support flax-leaved broom management.

They are competitive weeds in improved pastures, outperforming subterranean clover and ryegrass, and significantly reduce pasture production

The best way to control slender thistle is by encouraging competition from useful plants such as pasture.

Vigorous pasture minimises slender thistle establishment and growth.

Revegetating bare ground, preferably by insect resistant grasses may also impede the growth and spread of Slender Thistles.

Can establish in minor disturbed natural ecosystems, as well as established pastures and crops. Reproduces by seed and is dispersed through wind, water, agricultural produce, machinery, vehicles, wool and skins.

Produces a strong odour which may be a minor nuisance to humans. Grazing animals find it disagreeable, eating the plant only when it is young.

Small areas can be mechanically removed. Plants in flower must be burnt as seed will develop from the nutrient reserves in the stem if left on the ground.

Mowing reduces seeding but is effective only if is cut very close to the ground and repeated.

Regrowth often occurs if adequate soil moisture is present.

Seeds adhere to stock and other animals, and are carried in the digestive tract of animals. Seed spreads only short distances by wind but can travel longer distances by water and animal.

Extremely invasive and competes strongly with native vegetation and pasture. Wellestablished infestations can largely eliminate all other plants and restrict recruitment to the overstorey.. When eaten by livestock, it causes photosensitisation of exposed skin, affects the nervous system of animals causing depression and hyperthermia.

Grazing St John’s wort offers a costeffective, longterm control method in all situations; however, it is often the only practical method for steep, inaccessible hill country. Care needs to be taken to avoid poisoning when grazing St John’s wort.

Reproduces from creeping roots and by seed.

An aggressive intruder that tends to displace indigenous flora.Access to recreational areas may be severely restricted where thickets establish.

Young plants can be pulled out, dug up, or cut, but remaining stumps and small pieces of root will generate new shoots.

Encouraging or establishing alternative groundcover provides competition to ailanthus.

Chemical sprays may also be used

Slender thistles are dispersed solely by seed which can be carried for long distances in the wind. Seeds have a parachute of barbed hairs (the pappus) which aids wind dispersal and attaches to clothing and animal coats, particularly the fleece of sheep. is spread in contaminated hay, silage and grain and on farm machinery, and can be dispersed in water.

They can be widely scattered and are efficiently spread by moving water.

Cormils are also spread by slashing equipment, farm implements, vehicles, birds, rabbits and stock and can be dispersed in hay, silage and grain.

Forms dense stands which exclude other vegetation.

Suspected to be poisonous to livestock. Wild watsonia impoverishes soil and crowds out desirable pasture plants

Application of a registered herbicide and through physical removal.

Spread through birds, illegal dumping of garden cuttings in bushlands, roadsides and waterways

English Ivy is an aggressive, highly invasive weed.

Deprives habitat and food sources for indigenous wildlife, discouraging native birds, butterflies and insects. Ivy forms mats which suppress all ground level plants, preventing natural regeneration. All parts of the plant are poisonous if ingested, and the sap is an irritant on contact.

Small plants can easily be hand pulled when the soil is soft. Cut and paint works best for larger plants. Cut close to the ground. Be sure to paint the cut as quickly as possible to ensure the plant absorbs the poison.

This creeper is highly invasive and aggressive. It suckers and can form large mats on the ground and large masses in the canopy of trees. It smothers trees and shrubs and can restrict sap flow in the soft barked plants it grows around. It can also cause premature deterioration of fences and buildings.

Hand removal is the best option as this method reduces site disturbance and allows more specific selection of species as opposed to spraying.

Ensure that as much of the root system is removed to reduce the amount of regrowth.

Invades damp to wet areas. Prefers shade but grows in full sun provided conditions are moist the majority of the time. It can completely dominate the understorey.

Small infestations can be forked which is best done when the soil is moist, usually following rain.

Ensure that all roots and stems are removed, otherwise the plant will continue to grow. Dispose of plant material carefully as it spreads very easily. Adding surfactants may improve the effectiveness of some herbicides.

Spreads through seeds, however it tends to spread more through branches taking root when contacting the ground. Dumped garden waste and contaminated soil also contributes to its distribution.

Mainly spreads vegetatively with little or no seed dispersal. Stems grow up and arch over, taking root as they touch the soil. Leaf nodes will also take root.

Plants are dispersed through dumping of plants or soil containing parts of stems or roots.

Tradescantia

5

English Ivy

Spreads rapidly along the ground.

Each leaf node along a stem is able to root and form a new plant with stems capable of spreading several metres each year. The weed spreads rapidly in bushland areas from dumped garden rubbish. Stems are able to survive for up to 1 year without contact with soil or roots.

Forms a smothering carpet across the ground that can be over 500 mm thick. It displaces indigenous ground covers, herbs, grasses and orchids. Leaves are a common cause of skin rashes in pets, particularly on the stomach area.

It is toxic to cattle. It invades damp, wet and shaded areas of ground story and is widespread along creeks and waterways.

All roots need to be removed and disposed of correctly while minimising disturbance to surrounding soil. If in a thick mat it is possible to roll the weed on itself like a carpet using a rake. This will pick up the majority of it, then follow up over several years to remove rooted fragments. A herbicide soray will also control the weed.

Segments or fruit drop to the ground and take root.

Droppings from birds, foxes and other animals aid in the dispersal of seeds in distances of over 1 km.

Detached segments can also be transported by flood waters and may also attatch itself to wool and hides of animals and to footwear and tyres of passing vehicles.

A host to the fruit fly. Patches of weed may also provide a longterm harbor for pest animals such as rabbits. Dense infestations may hinder access to water and may also form impenetrable barriers. The barbed bristles penetrate human skin and are difficult to remove causing severe irritation.

Use of herbicies is optimal for killing off Prickly Pears.

While the plant is still young, the plant may be removed by grubbing manually or by machine. It is most effectively grubbed while the soil is moist and removal of all roots must be thorough to prevent reestablishment.
