ABSTRACT Gemerden, van, B.S, G.W. Hazeu, 1999. Landscape Ecological Survey (1:100,000) o/the Bipindi-Akom lI-Lolodorf region, Southwest Cameroon. Wageningen (The Netherlands), Tropenbos-Cameroon Documents 1,212 pp.; 13 Figs; 14 Tables; 81 Refs; 6 Annexes. In Southwest Cameroon a reconnaissance reconnaissance scale survey of landforms, soils and vegetation was was carried carried out. The survey survey area covered some 167,000 ha. The altitudinal range was was 40 to 1,000 m.a.s.1. Landforms discerned are: mountains, complexes of hills, isolated hills, hilly and rolling uplands, dissected erosional plains, and floodplains. Four soil types were described, ranging from well drained drained very very clayey soils (in the mountain area) to to very poorly to poorly drained drained soils (on (on valley bottoms). The The seven seven main main vegetation types include include four types of primary to old secondary rain forest (bound to different altitudinal zones), young secondary forest, swamp forest, and secondary shrubland. The patterns of landforms, soil types, and vegetation types are integrated into one 'landscape ecological' map (scale 1: 100,000). The legend has a hierarchical structure. It is based primarily on a subdivision in four altitudinal zones, secondly on landform, and finally on the degree of disturbance of the natural vegetation by shifting cultivation. Keywords: Africa, reconnaissance survey, rain forest, landforms, tropical soils, vegetation, altitudinal zonation.
