Abstract

Batur Forest is a volcanic area that was an ex-volcanic eruption. Efforts to rehabilitate forests with critical land were 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 were dominated by hard rocks. The research was done for a year (2019-2020). The method used was a species test with a 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 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 makes up the savanna forest ecosystem and volcanic critical land in eastern Indonesia.

Abstract

The Mount Picis and Mount Sigogor Nature Reserves in Ponorogo Regency, East Java, are conservation areas with significant potential for high biodiversity, including habitats for protected species such as the Javan Hawk-eagle and the Javan Leopard, as well as vital environmental services. This study aims to formulate a strategy for developing sustainable ecotourism-based nature tourism in the Mount Picis and Mount Sigogor Nature Reserves, Ponorogo Regency. The data from this study were analyzed using the SWOT method, identifying internal and external factors. The area's main strengths include its ecosystem integrity and rich flora and fauna diversity, while opportunities came from local government support and the participation of buffer communities. However, significant weaknesses include limited management facilities and infrastructure, suboptimal area data, and external threats such as low community well-being and the risk of forest fires. Based on this analysis, two main strategic objectives were formulated: (1) Increasing research and education based on biological potential, and (2) Maintaining the security and integrity of the area. The implementation strategy includes developing a potential database, adding infrastructure, improving human resources, and securing the area integrated with the economic empowerment of communities in the buffer zone. The conclusion of this study is that ecotourism development in the Picis mount and Gunung mount Nature Reserve must be carried out adaptively, prioritizing conservation, and involving the active participation of local communities to ensure the sustainability of the ecological and social functions of the area.
