Conservation of the wild Coffea arabica populations in situThe final reserve zones are mapped based on the suitability classes of the sites andthe land-use type of the constraint area. Areas that are highly suitable in the OWA1suitability classes and some very small areas those are moderately suitable, but embeddedwithin a larger area of the highly suitable class, are classified as parts of the core zone.However, very small areas of the high suitability class that are surrounded by moderatelysuitable areas are excluded. Hence, the moderately suitable areas and very small, isolatedareas of highly suitable areas embedded within the moderately suitable class of OWA1 areclassified as buffer zone-I. The percentage of the forest area in the less suitable class ofOWA1 is almost zero and does not count in the final zoning. The forest areas managed by thelocal people for coffee production are classified as buffer zone-II. The surrounding farmlandsand settlement areas are classified as the transition zone. The management zones for thecoffee reserve are presented in Figure 6.6 and Table 6.6 below.119
