Council's biosecurity team were recently alerted to the online sale of water lettuce (Pistia stratiotes), a regional priority weed, from a residence in Cooma.
The plants were initially purchased interstate by the individual who was unaware of its status as a regional priority weed. Once biosecurity officers explained the status of the weed and its potential to impact on the environment the plants were surrendered for destruction, preventing the risk of spread and safeguarding local waterways from potential harm.
This swift response highlights the critical role biosecurity plays in protecting our environment and economy from the threat of invasive species.
Water lettuce is one of several aquatic weeds that pose significant risks to local ecosystems, recreation and tourism.
Invasive aquatic species can rapidly infest waterways, blocking sunlight, depleting oxygen levels and disrupting aquatic life. They can also impede access for boats and people, reducing the recreational value of water bodies in the region.
Council urges the public to be aware of the risks associated with purchasing plants or seeds from unregulated online sources, especially those offered for sale from other states. Legislation governing the sale, transport, and introduction of certain plant species varies between jurisdictions, and what may be legal in one area could be a prohibited weed in another.
Council's biosecurity team will continue to monitor and address emerging threats to the region's environment and economy, but the public's support in staying informed and following local regulations is crucial to protecting our natural resources.
