Bush lines, riparian zones, undeveloped and non-arable areas have been excluded from production and are kept free of invader species to allow the re-growth of indigenous plant species. Plants categorised as weeds and invader species according to the Conservation of Agricultural Resources Act 1983 are identified and systematically eradicated. This is coupled with the rehabilitation of indigenous plant species in the areas that have had alien vegetation removed.

These zones are managed as conservation areas and are progressively rehabilitated to encourage fauna and flora species indigenous and endemic to the area. Growing crops within these areas does not conform to the principles of conservation management. In the interests of promoting conservation, large-scale unsustainable exploitation of natural resources from the conservation areas is restricted. Hunting is not permitted on any CBL Estates and anti-poaching patrols are carried out by security.
