Summary:We assessed the biomass of the planted forests of 2 main species (Eucalyptus camaldulensis and Acacia catechu) and biotic climax of shrub and grass communities in the central dry zone of Myanmar to provide a potential level of carbon sequestration by planted forests under the drier climatic conditions (mean annual rainfall of 637 mm). The biomass including roots of the 9 planted Eucalyptus camaldulensis forests of 6- to 11-year-old (at the 4 x 4 m planting spacing) ranged from 3.80 to 27.68 Mg hasup(-1), averaging 14.83 Mg hasup(-1). The mean annual increment (MAI) was estimated as 1.68 Mg hasup(-1) ysup(-1). The biomass of the planted Acacia catechu forest of 7-year-old (at the 4 x 8 m planting spacing) was estimated as 10.62 Mg hasup(-1) and its MAI was 1.52 Mg hasup(-1) yrsup(-1). The results show that the productivity of the planted forests is much lower than that of other places with more favorable conditions. The sum of biomass and litter weight of biotic climax of shrub and grass communities ranged from 2.36 to 23.14 Mg hasup(-1), averaging 11.00 Mg hasup(-1). Since tree growth is seriously compromised by the drier climate of the study area, the establishment of a productive planted forest requires new technological inputs such as fertilizer application, mulching, irrigation, use of drought-tolerant species, and protection from destructive elements.
