Clarence Reserve

The Clarence Reserve is located in North Canterbury between the Inland and Seaward Kaikoura ranges. It is an area of known TB infection in wildlife species and home to a long standing TB-infected cattle herd.

The Clarence Reserve has been identified as a TB management area (TMA) and is the focus of a nine-year TB management plan that began in summer 2017. The pest control stream of the plan targets possums to achieve TB freedom in both livestock and possums.

Objectives

  • TB freedom in livestock by 2023
  • TB freedom in possums by 2026
  • TB freedom in the Clarence Reserve TMA by 2026

Background

The objectives of the TBfree programme include achieving TB freedom in livestock by 2026, in possums by 2040 and eradication of TB from all hosts across New Zealand by 2055. These goals will be delivered through a framework of TB Management Areas (TMAs) – areas of common disease patterns, geographical features, control history, and future control needs.

The Clarence Reserve, identified on the map above, is a TMA and an area of known TB infection in livestock and wildlife. This has been confirmed through the identification of TB in possums, deer, pigs and ferrets and farmed cattle.

The Clarence Reserve TMA will be subject to a focused programme that includes ground-based and aerial pest control activities and wildlife surveillance.

Pest Control Programme

The TBfree programme aims to achieve TB freedom in possums in the Clarence Reserve TMA by 2026. For information on operational activities, follow the links below:

Disease Management Programme

Our disease team are working directly with infected herd owners to achieve TB freedom in livestock by 2023.

Information for Hunters

Warning signs will be placed at all main access points to aerial pest control areas undertaken as part of the Clarence Reserve TB programme. All land users, including hunters, must follow the cautions on these signs.

Individual aerial pest control operations will have an associated TB control operation notice – these notices provide instructions to ensure the safety of land users within pest control areas. These notices can be found under the ‘TB freedom in the Clarence Reserve’ heading above.

For further information on access permissions and permits required to hunt in the Clarence Reserve you will need to contact the Department of Conservation South Marlborough Area office and the owners of private property or lease hold in the area.
