Structure and function of a sub-tropical humid forest of Meghalaya I. Vegetation, biomass and its nutrients (original) (raw)
Abstract
The peripheral disturbed zone of a 50-year old stand of the forest at Lailad was dominated by_Dendrocalamus hamiltonii_, an early successional bamboo characteristic of a secondary successional fallow of not more than 20–25 years while the central undisturbed zone had_Schima wallichii, Castanopsis indica_ and_Shorea 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 between_dbh/d_ 2 h 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.
