Help flush out the 'Dirty Duo'...

Wanted Moth Plant and Wild Ginger

You may have seen these signs up around Kaipātiki recently. PFK are on a mission to help residents get rid of these most invasive weeds from backyards and neighbourhoods in the Kaipātiki Local Board area.

These pest weeds are invasive and a danger to our native bush. They are on the Department of Conservation’s “Dirty Dozen” list of pest weed species.

Moth plant vine (above) strangles mature trees and forms large green seed pods. One seed pod can infest neighbourhoods anywhere within a 30km with 1000s of airborne seeds.

Wild Ginger / Photo: Supplied

Wild ginger (above) is a space invader - it competes with the native plants that feed native wildlife. Once they get a foothold they are very hard to get rid of.

Right now, they are easier to spot as they are flowering, and now is a really good time to remove them, before the seed pod and seed heads form and seeds are spread by the wind!

The more of us that can help “Recognise, Report and Remove” this Dirty Duo, the more chance we will have of kicking these weeds out of Kaipātiki! Help us find and remove them now before they take over.

We’d like all Kaipātiki residents to report any sites of wild ginger and moth plant on public or private land - in reserves, on roadsides, or on private property - particularly larger infestations.

Our Volunteers - aka the Dirty Duo Hit Squad - have already begun removing weeds and are using the app to record their removal work and record sites.

Reporting your site by using the app will help us coordinate teams, map the spread and monitor sites over time.
