Reedbuck, Waterbuck, Lechwe, Puku >>

Distribution - Strategy

Strategies Requirements

Re-establish viable breeding nuclei of waterbuck and puku by introducing significant numbers of these species to the Caprivi after a good rainy season.

 

Develop co-management institutions between the State and conservancies in areas where conservancies border on to national parks to achieve larger ranges of reedbuck, waterbuck, lechwe and puku.

Establishment of co-management institution to manage floodplain habitats

Public and political support;

Coordination and collaboration with communities neighboring parks in the Caprivi;

Full devolution of authority for the species to the landholders;

Dialogue with land use planning authorities;

Transboundary cooperation;

 

 

Re- introductions of waterbuck and puku

Re- introductions of waterbuck and puku should ideally coincide with the inception of a period in which the cumulative rainfall deviations are in a surplus mode. This is simple to calculate from existing rainfall data (see Appendix 4). However, it may be possible to do it following any good rainy season. The introduced population may not increase rapidly until the long term rainfall is in a surplus mode, but the nucleus may persist until that time.

Experience gained from introductions in different parts of the region is that, if the animals are free-released, predators may take almost the entire number. Equally, holding them in bomas for a long period arouses predators' interest and, when they are finally released, the attrition may be equally severe. There is no simple solution but the practices being adopted by Malilangwe Conservation Trust (Derek de la Harpe, pers.comm.) may offer the highest chance of success.

  • Introduce large gropus of animals rather than 'fiddle' with small groups, which may or may not survive and which, in any case, will take a long time to increase to carrying capacity.
  • Breed a substantial number of animals in large paddocks. Release groups, which are large enough to give most individuals a fair chance of survival. Retain a nucleus of breeding animals until no longer needed.
  • One of the reasons the animals fall easy prey to predators is their lack of familiarity with the terrain into which they are finally released. To counter this, construct a large 'pre-release boma' at the actual site where it is desired to re-introduce the animals. Move gropups that are to be released from the main paddock to the pre-release boma. Animals are still protected from predators and are given enough time to familiarise themselves with the terrain in which (it is hoped) they will finally settle.
  • Remove the pre-release boma over a period of time. Initially, create openings in the boma so that animals may disperse if they wish to. The animals have the option of returning to familiar terrain if threatened by predators. The boma is fully removed over several weeks or months.
