The Weed Spotters' Queensland Network includes more than 1,000 trained weed spotters who keep watch for new weeds in their local area and collect specimens of potential new weeds for identification by the Queensland Herbarium.
The Weed Spotters Network Queensland bulletin includes information about new and emerging weeds.
The Queensland Herbarium produces the Census of the Queensland Flora that lists the native, naturalised and doubtfully naturalised species.
We are working with the community and Biosecurity Queensland to monitor how non-native plants are introduced and naturalised in Queensland and to detect potential new weeds through the Weed Spotters’ Queensland Network.
Naturalised species are those that have successfully established themselves outside their native habitat by reproducing there without cultivation or human intervention.
Many species have become naturalised in Queensland since European settlement. Most originated outside Australia and were imported for food, fodder, as ornamentals, or by accident. A few are native species that have spread to new areas outside their natural distributional range.
- Naturalised species are increasing at a rate of approximately 10 new species becoming established each year
- There are 1,326 species naturalised in Queensland (2016 data). More than 100 of these are declared pests and there are an additional 360 species listed as doubtfully naturalised.
