Health assessment of vegetation composition in the reclamation area of PT Natarang Mining, Tanggamus Regency, Lampung Province

Abstract

Reclamation is a recovery activity in mining areas, one of which is revegetation. The success of revegetation plants can be seen from the health of the composition and structure of the vegetation when the trees are six years old and over. This study aims to determine the health of the vegetation composition (location, type, and level of tree damage) in the reclamation area of PT Natarang Mining, Tanggamus Regency, Lampung Province. The location of this research is in the area around the main office of PT Natarang Mining, Way Linggo Forest, Bandar Negeri Semuong, Tanggamus Regency, covering an area of 2.97 Ha. The research was conducted through vegetation analysis using the circular plot method and assessing the health of the vegetation composition based on the damage index at the plot level. The results showed that tree vegetation obtained 12 species. The most common tree species found was Falcataria moluccana (Sengon) which amounted to 22 individuals. The most significant contribution of tree species indicated by the highest importance value index was Falcataria moluccana. The location of most damage found in most of the plots was at the bottom of the stem (code 3) and the bottom and top of the stem (code 4). Types of open wound damage (code 03) and gall rust (code 26) were the most dominant causes of damage, with an average damage rate of 35% and 22%, respectively. The health value of the vegetation composition has a value range of 1.20 – 2.00. The average health value of the vegetation composition is 1.50, which is included in the medium category.

Study of Vitality Change in Teak Community Forest Management (Case Study on Teak Community Forest in Natar Sub-district, South Lampung Regency, Lampung Province)

“…This tree damage may prevent the forest from performing its current functions [17]. Tree damage will have a negative effect on wood quality and community woodlands health [18].…”

“…Based on the criteria for damage with forest health monitoring approaches, the tree damage assessment comprises the location of the damage, the type of damage, and the level of tree damage in each tree (Forest Health Monitoring) [12]. Damage that satisfies the criteria in accordance with pre-established requirements is the sort of damage assessed [18].…”

“…Utilizing tree damage condition characteristics, one of the signs is the vitality indicator. Calculating damage location, damage kind, and harm severity yields vitality numbers [18]. A tree is considered healthy when it is able to perform its physiological functions and is resistant to pests and other external factors.…”

Factors Affecting Community-Managed Forest Health

“…Broken branches were generally created from tree borer pests that prefer to attack the branch due to its softer nature. This type of damage to broken branches could be overcome by tree maintenance, such as pruning branches that have been indicated by fungi and parasites [14] [19].…”

Forest Health Analysis Based on Flora Biodiversity Indicators in Gapoktan Harapan Sentosa KPHL BatuTegi, Lampung

“…Forest health measurements are designed to determine the state of the forest and identify the right plan to overcome and improve it. From an ecological point of view, a healthy forest refers to a forest in which all components contained in the forest exhibit balanced interactions [15].…”
