Supporting plant resellers to understand plants prohibited from sale
Landscape Officers support plant resellers to understand what declared plants they cannot sell in the Limestone Coast. This includes inspections of businesses such as nurseries and florists for declared plants prohibited from sale.
The inspections, undertaken by authorised Landscape Officers, are just one tool in the prevention of weed spread across the region.
We recognise that there are other ways in which our community buys, swaps and sells plant. This includes online community buy, swap and sell groups. We actively work with the community to improve their understanding of what plants cannot be bought, swapped or sold.
If you suspect you have a declared plant or a declared plant is being offered for sale or swapping
If you think you have a declared plant or believe declared plants are being offered for sale or swap you should contact a Landscape Officer with the Limestone Coast Landscape Board.
Our Landscape Officers will provide assistance with identifying the plant and supporting you or those offering the plant for sale or swap to control and destroy the declared plant if required.
Our Landscape Officers are here to help, talk to them today
