Yield models for Eucalyptus globulus fuelwood plantations in Ethiopia

Abstract

Based on 53 tree analyses and 105 sample plots of Eucalyptus globulus, models for volume and biomass at single tree and stand levels were developed. The possible growing sites were divided into four site classes. In seedling stands, the site class I corresponds to yield class 44 m³ ha⁻¹ year⁻¹, in coppice stands to yield class 46 m³ ha⁻¹ year⁻¹. The site class IV corresponds in seedling stand to yield class 9 m³ ha⁻¹ year⁻¹, in coppice stands to yield class 13 m³ ha⁻¹ year⁻¹. The maximum mean annual increment was reached in seedling stands at the age of 18–19 years, in coppice stands at the age of 14 years.
