    • Abstract

       

      The peripheral disturbed zone of a 50-year old stand of the forest at Lailad was dominated byDendrocalamus hamiltonii, an early successional bamboo characteristic of a secondary successional fallow of not more than 20–25 years while the central undisturbed zone hadSchima wallichii, Castanopsis indica andShorea robusta as important components. The biomass of the forest was computed as 137×108 kg/ha of which 64.7% was in the central zone. The contribution by different species both in the central and peripheral zone of the forest was worked out. Linear relationship betweendbh/d2h and biomass was worked out for different species. The standing crop had: N, 953; P, 284; K, 600; Ca, 2281; and Mg, 450 kg/ha, of which 60% was in the central zone of the forest.
