Service Empowers Community to Track and Combat Invasive Weeds

The local board is embracing technology in its ongoing battle against invasive species with a new online service, 'Aotea High Risk Weeds'. This initiative will enable the community to actively track and manage weed infestations across the motu, protecting its rich biodiversity.

Home to over 575 native plant varieties, Aotea is a hub of biodiversity, representing a quarter of New Zealand's flora. However, the presence of around 300 introduced plant species, some of which are high-risk, poses a significant threat to this delicate ecosystem.

“Our native ecosystem on the motu is special to all of us, and this is a great opportunity to help protect it,” says Izzy Fordham, the local board chair. Residents and visitors are encouraged to join the 'Aotea High Risk Weeds' project on iNaturalist, aiding in the identification and reporting of invasive species.

The Auckland Council’s Natural Environment Delivery Islands team, which has been monitoring these weeds since 2011, will greatly benefit from the community’s involvement. “The data collected from weed surveillance helps us prioritise which weeds to manage before they become too widespread to control,” explains Niklas Erikson, a senior conservation advisor. “It’s extremely helpful that the community are jumping on board with the Aotea High Risk Weeds project to further our understanding of these high-risk species. We’re grateful for the locals who have taken the time to contribute so far.”

Public reporting of these plants on iNaturalist will lead to Auckland Council arranging for pest plant control using local contractors. This initiative underscores the importance of early intervention in weed management, where removing a young plant can prevent the need for more extensive control methods later.

The community is also urged to dispose of garden waste responsibly and participate in weed amnesty days. Alternatively, pest plant sightings can be reported by emailing a photo and the location to pestfree@aucklandcouncil.govt.nz.

This initiative is part of a broader effort to tackle biodiversity threats on Aotea, complementing the ongoing battle against the invasive caluerpa in the oceans. Through this collective approach, the island aims to protect and preserve its rich natural heritage.
