Abstract

Forests, traditional gardens and green spaces play an important role in regulating the water flow of an area. Along with the high demand for land in Bali for agriculture and tourism, many forest areas have been converted into hotels and settlements. Forest conversion has caused many problems such as erosion, soil fertility decreased, flora fauna extinction, floods, drought, global warming and the disturbing watershed, especially rivers for springs. The purpose of this study is the development of watershed conservation in Bali based on traditional agroforestry. The method that used is vegetation analysis. Calculation of the erosion amount using the USLE formula. Sampling was done by ten plots. The results showed that traditional agroforestry vegetation consisted of vertical and horizontal structures. The characteristic of traditional agroforestry is that dominant plants are distributed irregularly, thus creating a miniature structure like a forest. The vertical structure consists of trees, horizontal structure filled with species of garden plants and agriculture. Trees have roots spread intensively in the soil and reduce nutrient leaching. Land cover by vegetation protects the soil and erosion. The agroforestry has a role as an act of soil and water conservation. Traditional agroforestry land cover has a relatively low C coefficient (0.05-0.25) compared to other lands. The level of erosion hazard is low and moderate. Average erosion value of 55.01 t.ha-1.yr-1. This indicates that traditional agroforestry makes the soil have a higher ability to absorb water, thereby reducing surface runoff. Likewise, organic material that improves the water content capacity. In addition, water quality can be improved through the humus filter function. During a long dry season, there is a drought due to low rainfall, but rivers and springs were able to supply water for the peoples daily needs. This condition occurs because of the tree retentions in traditional gardens. Conservation actions need to be taken, namely maintaining trees vegetation, increasing reforestation, bench terraces use, mounds and mulch use. This condition also places traditional agroforestry as a sustainable land management system.

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.
