Port Macquarie-Hastings Council in association with local Landcare groups and the Hastings Birdwatchers hosted the event at the Laurieton United Services Club.

Council's ecologist Dr Rebecca Montague-Drake said the night was a great opportunity for local residents to learn about the precious flora and fauna thriving in the Camden Haven.

"We want to send the message that there are weeds in gardens that can greatly impact the native bush at our back door," she said. 

Dr Montague-Drake said a lot of people don't realise a lot of weeds can still be purchased at local nurseries, however they pose a threat to the native flora and fauna. 

"A lot of the weeds have berries on them and are prone to spreading throughout the region."

There was a weed swap table hosted by Landcare at the event. 

The aim was to encourage people to have any harmful weeds swapped with a native plant for free. 

The evening allowed residents to learn more about biodiversity and gave them the opportunity to talk to conservation and land management experts.
