This manuscript comprises two parts: Part I Vegetation type mapping Part II Species/volume distribution for those vegetation ty pes that carry potential merchantable forest Part I describes the identification and delineation of vegetation types by airphoto interpretation. The photographs used were black and white Skaipiksa series which covered the whole country over the limited time frame of 1973-74. Recognisable and distinctive patterns of natural vegetation were mapped at a scale of 1:100 000. All forested areas received a disturbance rating. The resultant map, whilst using terminology similar to that of the Forest Resources o f Papua New Guinea map (Saunders 1993b), is not genetically related to it. This latter map was derived from the Vegetation o f Papua New Guinea map (Paijmans 1975) in combination with the Agricultural Land Use o f PNG map (Saunders 1993a). This current 1:100 000 vegetation map is not related, or linked to, the Papua New Guinea Resource Information System (PNGRIS). The similarity of the classification and terminology used does however allow for broad-scale cross-referencing to the vegetation types in PNGRIS. Part II allocates species percentages (on a merchantable volume basis) and gross volume/hectare figures to those vegetation types which are considered to have potential commercial value. As there is considerable variation in the species composition of particularly the plains and hill forests throughout PNG, a system of zonation was introduced. Each of the 42 zones contains a somewhat uniform major species distribution over the range of forest types. Species percentages and volume stated are based on gross merchantable volume for all species having a diameter of 50 cm and greater above buttress. The forest types considered merchantable are those that contain, under the above criteria, a minimum of 15 m3ha. Section A of Part II considers the methodology used to determine the species/volume distribution for all vegetation (forest) types. Section B details the results, on a provincial basis, for all forest zones located within that province. The exception to this is that all Highland provinces are included in the one reporting unit.
