The Department of Conservation (DOC) intends to control Himalayan thar (Hemitragus jemlahicus) to protect indigenous ecosystems affected by these introduced mammals. The department has reviewed the strategic options it has to do this, and has decided on a policy to limit the spread of thar and to restrict their numbers to below various nominated densities in different parts of their present range. A management plan has been prepared. This sets the densities at which DOC will intervene to control thar in each of nine management units and sets some rules for DOC and private hunters.
This research aimed to provide some of the ongoing ecological and management information to verify that the nominated thar densities were tolerable and that the capabilities of the different types of hunter to kill the required number of thar were realistic. The emphasis of the research work changed as the strategic policy and management plan clarified the aims of DOC, and although the report is technically a final one, many of the results are interim because the outcomes of the proposed management regimes will often take many years to be expressed. The results also need to be read in conjunction with a companion report on the diet of alpine herbivores. The research covered in this report began in 1989 and was commissioned from Weeds and Pests Division of Manaaki Whenua – Landcare Research by the Science and Research Directorate of the Department of Conservation.
