Pests and weeds in Marlborough
Marlborough is known across New Zealand and around the world for its beautiful landscapes and produce. From its vineyards and orchards to the picturesque Marlborough Sounds, biosecurity and biodiversity are key to the region’s success.
Rivers in Marlborough including the Wairau are threatened by the presence of invasive weeds such as gorse and broom which can spread quickly when seeds are transported during flood events.
Tackling the problem
Our annual works programme targets control to key areas on the Wairau, Awatere and Clarence rivers to stop the spread of gorse and broom seeds downstream.
The most effective control method for managing gorse and broom in braided rivers is through targeted and controlled spraying.
Working with others
In Marlborough we plan our work with the Marlborough District Council to make sure it supports the Marlborough Regional Pest Management Plan
How you can help
All lake and river users also have a role to play in stopping the spread of water weeds. If you’re moving between waterways, you must clean all your gear using the 'Check, Clean, Dry' method. This stops plant fragments moving between waterways, which can be all it takes for a new infestation to begin.
