Biomass and volume tables for Eucalyptus camaldulensis, Dalbergia sissoo, Acacia auriculiformis and Cassia siamea in the Central Bhabar-Terai of Nepal

Working paper

Single entry biomass tables of oven dry and fresh weight, based on the equation Ln Weight = a + b Ln DBH, (diameter at breast height) are presented for Eucalyptus camaldulensis Dehn., Dalbergia sissoo Roxb., and Acacia auriculiformis A. Cunn. ex Benth. Oven dry and green weight single entry tables are given for Cassia siamea Lam. using diameter at ground level (5 to 10 cm height) as the predictor variable. Single entry overbark and underbark total volume tables are given for E. camaldulensis and D. sissoo using DBH as the predictor variable.

The E. camaldulensis biomass and volume regressions were compared with two Eucalyptus tereticornis and two E. camaldulensis provenances. There was no significant difference between the equations of the four provenances for volume or stem biomass. The tables for all of the species have been validated for short rotation clean weeded plantations in the Bhabar-Terai region of Central Nepal.

The yield of the four species was estimated for different sites, ages, and spacings using the equations developed. E. camaldulensis and C. siamea are the most productive species with an oven dry fuelwood (stem and branch) MAl at age 4.5 and 2.5 years of 14 and 10 tons per ha respectively. E. camaldulensis, at the short rotation stocking of 10,000 stems per ha did not produce appreciably greater yields than a stocking of 2,500 stems per ha by age 1.5 years.
