Description: A dense , low ground cover with lobed, glossy leaves and brown/maroon runners

rooting wherever they contact the soil. Distinctive yellow daisy flowers are formed year round.

The plant spreads mainly from stem from fragments and runners.

Distribution: Singapore daisy has a limited distribution across the Hinchinbrook Shire.

Impacts: Singapore daisy forms dense mats smothering out native vegetation and pasture. The

plant is allelopathic, releasing a toxin which inhibits the growth and germination of other plants.

Key projects: A targeted program using selective herbicides is underway to treat all known

infestation within Hinchinbrook Shire area.

Prevention

Singapore daisy can be spread by slashing operations and garden waste.

Careful management of machinery and gardening practice in vicinity of known

infestations will help reduce spread to new areas.

Singapore daisy is often associated with water ways and may have been used

in the past in an effort to stabilise creek banks or drains. Ensuring clean soils

and sills are used in earthworks will assist prevent spread between

properties or along waterways.

Intensive

control

To assist the program any new or untreated infestation should be reported to

council. Landholders should ensure they do not spread in contaminated soil

or on machinery. Slashing and mowing of known infestations should be

avoided as even small plant fragments can establish new infestations.

The council led management program can be assisted by providing clear

access to infestations for the control team. Longer term site recovery may

require revegetation with local native plants to stabilise soils and provide

deep shade to reduce habitat for Singapore daisy.

What is my biosecurity obligation?

Prevention zone

Report any suspected outbreaks or detections to Hinchinbrook Shire

on 07 4776 4607.Ensure any machinery or vehicles moving from the infested areas are

free from plant material and soil.

Intensive control

zone

Ensure best practice weed hygiene measures are in place to reduce

risk of spread to new locations. Maintain weed free areas. Identify

high value assets and protect them from impacts where possible.
