414 management inputs to augment forest product yields or maintain site capability, and, where agricultural use competes with forestry for the site III non-forestry lands: lands which support vegetation types which do not yield significant amounts of forest products and where agriculture is the primary land use The individual TU’s were placed in their respective categories and a total surface area was calculated. Table 2 shows the placement of each TU in one of the three categories, and Table 3 shows the comparative surface areas of each category for the two arrondissements.

Not only are they associated with forestry conditions, but they are also very standard types of ground conditions, which do not change appreciably (perhaps with the exception of vegetation species composition) with time or locale. The basic classification system, embodied in the photo examples of the key, has the potential to be applied throughout the sahelian region of Africa, leading to a real possibility of integrated, regional, planning activities. Work is at present under way in pursuit of this application. REFERENCES Daus, SJ. et.al. Final Report, Mali Land Use Mapping Project (Projet d’inventaire des Ressources Naturelles, PIRT), contract.

In addition, after an appropriate period of training, the GON forestry personnel were able to implement all aspects of the mapping procedure. The procedures do not depend on complex techniques, nor do they require complicated or fragile equipment. These are techniques which can be conducted in the office or in the field. This is a mapping procedure that is suitable for conditions often encountered in developing countries. 4.2 Flexibility of the mapping procedure A primary criteria in basing the mapping system on the interpretation of aerial photography, and in the development of the photo interpretation key, was the desire for flexibility and regional applicability. For good reasons were the specific types of ground
