Abstract
Eucalyptus urophylla is one of the typical plants of the Province of East Nusa Tenggara, Indonesia whose distribution includes the islands of Timor, Alor, Wetor, Flores, Adonara, Lomblen, and Pantar. The best land for the growth of E. urophylla is an area with rainfall above 1000 mm every year. E. urophylla dominate the island of Timor hence the potential to absorb carbon and store it in biomass as part of climate change mitigation. This study aims to determine the allometric equation model to predict the potential of E. urophylla stem biomass. Calculation of the amount of stem biomass based on allometric equations is an analytical method used in this study. The sample trees used in equation modeling is 100 trees as a result of the inventory. The equations that can be used to estimate the biomass potential of the stem of E. urophylla in Timor Island were ln = -2.12 + 2.472 ln ( ) and (R2= 0.98); ln = -3.617 + 1.046 ln and (R2= 0.99); and ln = -3.510 + 2.157 ln ( ) + 0.983 ln and (R2= 0.99). The stem biomass potential with the model I amounting to 276.877 tons ha-1, model II of 279.671 tons ha-1, and model III of 280.209 tons ha-1.
Highlights
The forest area of Timor Island, Indonesia is one of the forest areas that still has an area with a level of closure in the form of primary forest and secondary forest
E. urophylla is one of the plants that dominate Timor Island and is suitable to be used to predict the potential of stand biomass in forest areas in East Nusa Tenggara Province
This study aims to: (1) developing the model for estimating the biomass of Eucalyptus urophylla stem, (2) Providing the information of biomass and carbon stock of Eucalyptus urophylla stands in the study area
Summary
The forest area of Timor Island, Indonesia is one of the forest areas that still has an area with a level of closure in the form of primary forest and secondary forest. The two types of closure are partly dominated by Eucalyptus urophylla. The Gunung Mutis Nature Reserve is one of the typical forest areas in East Nusa Tenggara, it has a uniform and relatively intact E. urophylla. E. urophylla is one of the plants that dominate Timor Island and is suitable to be used to predict the potential of stand biomass in forest areas in East Nusa Tenggara Province. The information about this biomass potency is very important to implementing climate change mitigation programs (Ochieng, 2017; Alloisio & Borghesi, 2019; CIFOR, 2010). Other research that supports the calculation of the potential of Eucalyptus biomass has been carried out by Latifah & Sulistiyono (2013) and Hernández-Ramos et al (2017)
