Eighty introduced plants species were identified by Douglas Shire Biosecurity Working Group as current or potential pests to one or more of the various land uses in the Douglas Shire Council area.
Of these, the pest plants with the highest priority rating were included in Council’s Biosecurity Management Plan.
Siam weed is scrambling woody shrub to 3 metres (sometimes higher as a scrambling climber) with distinctive forked leaf venation and purple flush on new leaves. Siam produces clusters of mauve-white flowers in May-June and October.
The weed is known to be localised and occasional in the Killaloe and Mossman area.
Impacts:
Siam weed can form dense thickets and outcompete native species and pasture in both disturbed and undisturbed sites.
Key Projects:
Siam weed remains a long-term management target in the Douglas Shire area. For larger infestations Douglas Shire Council will work with landholders to develop a property biosecurity plan.
Contact DSC to report any suspect plants on 07 4099 9444.
