Descripción
Batur Forest is a volcanic area that was ex-volcanic eruption. Efforts to rehabilitate forests with a critical land was by planting Eucalyptus urophylla. The aim of the study was to examine the adaptation of Eucalyptus urophylla species in critical areas of former volcanic eruptions that was dominated by hard rocks. The researches were done for a year (2019-2020). The method used was species test with permanent block plot design from 4 age levels, 1 year, 5 years, 10 years and 15 years. The study results showed growth of 1.02 cm in diameter and 1.10 m in height (1 year), 6.50 cm in diameter and 11.00 m in height (5 years), 13.25 cm in diameter and 18.40 m in height (10 years) and a diameter of 20.48 cm and a height of 23.00 m (15 years).
Eucalyptus urophylla experienced the best tree diameter growth after 10 years old and on the contrary experienced a decrease in height. The Eucalyptus urophylla level of adaptation and suitability of on volcanic soils with low fertility and rocky soil is a recommendation to increase the quantity of this species of planting. So that the forest succession from rocky thickets to tree vegetation is faster than natural processes. Eucalyptus urophylla species is one of the flora that make up the savanna forest ecosystem and volcanic critical land in eastern Indonesia.
