One of the essential component of in situ conservation is the establishment of Gene Management Zones (GMZs) which should be accessible, suitable and sustainable for long term conservation, evaluation, utilisation, monitoring, and management of the populations under consideration. GMZs are the places for continuation of evaluation within and between populations of plant species with endangered and/or vulnerable as well as high and unique genetic diversity in their selected habitats. Their number and size may vary according to the suitability and availability of resources. The target species should primarily be determined in terms of their genetic diversity. GMZs with their appropriate sizes could consist of more than one population for long term genetic conservation of the target taxa of wild crop relatives. To protect selected sites, buffer zones should be established as areas adjacent to protected areas, on which land use is controlled to provide extra protection to the core area containing target species. Buffer zones should have some restrictions in order to control human activities around the protected area. The management plan is needed to manage and maintain genetic diversity at GMZs; therefore, the establishment and management of GMZs requires a clear legislative basis. For secure protection, the core area should be managed by land-use regulations. As a basic principle, each GMZ needs a separate management plan. This guides and controls the management of protected area resources, the utilisation of the area and the development of supporting facilities
