Pest plants and animals are one of the greatest threats to the region’s remaining indigenous biodiversity.
Myrtle rust information
Myrtle rust has been found in Taranaki and other regions. Myrtle rust is a serious fungal disease that affects plants in the myrtle family, which includes pōhutukawa and mānuka. It is a threat to some of our iconic native plants as well as commercially-grown species. More information from MPI
How to report myrtle rust
Smartphone apps and a dedicated website are available to help you report myrtle rust. See Myrtle Rust Reporter
Introduced animals such as feral goats and deer eat native vegetation and damage habitats that are important to other native species.
Possums are a major threat to both native flora and fauna and can also transmit bovine TB to domestic livestock. Effective TB control requires possum numbers to be kept extremely low.
Many introduced plant species compete with native plants for space and resources changing native habitats, resulting in further biodiversity losses.
The Council’s main focus for pest animal control is possum control through our Self-help Possum Control and Urban Possum Control programmes.
We also monitor the management of other pests in the region and assist the Department of Conservation (DOC) to eradicate four species of exotic fish from our waterways. DOC is a very good source of information on how to stop the spread of pest fish in New Zealand.
Some species have potential to become new pests. The rainbow lorikeet, for example introduced parrot competes with native birds, dominating food sources and nesting sites. and damaging fruit crops. See the Ministry for Primary Industries website for more details.
Each pest plant identified has a management programme according to its designation. Our strategy focuses on controlling pest plants categorised for eradication and containment
We directly control four terrestrial pest plant species: climbing spindleberry, giant reed, mignonette vine and Senegal tea. We also control old man’s beard in the Kaūpokonui River catchment area. With some exceptions, land occupiers have obligations to control pest plants on their property.
Owners and occupiers
Under the rules of the Pest Plant Strategy land owners and occupiers are obliged to control containment plant species found on their property and we do inspect properties to ensure weed control responsibilities are being upheld. Our inspections focus on Category A, B and C properties
- Category A properties are managed to the Council’s satisfaction with no recent significant infestations of a containment pest plant on the property. Category A properties are visited as time and resources permit
- Category B properties are also are currently managed to the Council’s satisfaction but have recently had significant infestations of a containment pest plant. Category B properties are inspected at least once a year.
- Category C properties are properties that the Council considers inadequately managed. They currently, or in the previous season, have significant infestations of a containment pest plant on the property. Category C properties are inspected at least three times a year.
