Broom along roadsides can reduce visibility and increase road maintenance costs. Broom can form dense thickets in degraded pasture and reduce productivity and access.Given time, this species could become more common as an invader of bushland, roadsides and disturbed sites throughout Tasmania. Flax-leaf broom is known to be naturalised in several locations in the south and north-west.Montpellier broom is widely distributed in Tasmania's north, north-east and in the south.English broom occurs throughout the settled areas of the state, being locally abundant on roadsides, waste areas, poor quality pastures and in disturbed bushland.Brooms were originally introduced to Tasmania as garden plants.Widely naturalised on mainland Australia, brooms occur in New South Wales, Victoria, South Australia and Western Australia. A shrub in the pea family, (Fabaceae), broom is native to Europe and the western Mediterranean.If you are still in doubt about the weed you are dealing with, contact Biosecurity Tasmania on 03 6165 3777 for help.

If not controlled, brooms can modify native ecosystems by increasing the frequency and intensity of fire, changing vegetation structure, altering soil chemistry and providing harbour for invasive animals.Brooms establish rapidly after disturbance such as fire or grazing, but can also invade relatively undisturbed areas.When the seeds are mature and still attached to the parent plant, the pods open explosively to eject the seed up to 3 metres. Brooms grow quickly, produce large amounts of seed in pods, and can tolerate diverse environmental conditions.
