Performance Audit Report on the Control of F MD 2. FMD surveillance zone  3. FMD free/Non-vaccinated zone (green Zone)  Commonly known as the Yellow Zone or Buffer zone: These are areas at the  interface of the FMD prone areas (Red Zones) and FMD free areas (green zones). The country has one large FMD free zone which covers approximately two thirds  (2/3) of the country. The free zone is resident to approximately 85% of the  national livestock population. The zone covers a vast area of approximately 840  km long and 560 km wide. FMD free zone comprises of geographic disease  control zones: 3c (Dukwi), 3c (Maitengwe), 4a, 4b, 5, 8, 9, 10, 11, 12 and 13. The  FMD free zone is bordered by the FMD free zone of South Africa in the South and  South-East and the FMD free zone of Namibia to the West. Zimbabwe which is  an infected country and zone 7 are to the North East, and geographic disease  control zones 2, 3b and Makgadikgadi National Park (MNP) to the North. 13 In addition to these zones, there are stock free zones such as wildlife areas  (National Parks and Game Reserves). These zones are separated by a double  cordon fence, with one line being a 2.4 meter game proof fence and another one  being a standard 1.5 meter cattle fence. However, in areas colonised by  elephants, the DVS has decided that game proof fences not be used, rather  standard fences (shorter) be used instead, so as to minimise damage to fences  by elephants. 14  Most of the cordon fences are in the northern parts of the country  which are predominantly FMD free zones with vaccination and are highly  susceptible to FMD outbreaks due to presence of buffaloes in those areas. 15 $^{13}$ Establishment of a protection zone by re-designation of the OIE recognised FMD free zone of Botswana  $^{14}$ DVS-Fence Strategy  $^{15}$ Department of Veterinary Services-FENCE STRATEGY  16 |  P a g e
