Abstract

Trees are an important part of the compilation of forest ecosystems blocks of collections of plants and/or animals, Wan Abdul Rachman Forest Park, Lampung Province. Block collection of plants and or animals serves as a place for collecting, protecting and preserving biodiversity. The problems that occur in this block are changes in forest areas, initially primary forests become mixed forests due to land clearing. Land clearing causes various types of tree damage which causes a decrease in tree health and forest health, so it is necessary to identify tree damage conditions. The purpose of the study was to determine the condition of tree damage based on the location of tree damage, type of tree damage and severity. Identification is carried out using the Forest Health Monitoring (FHM) method, the measurement parameter is the condition of tree damage. The study was conducted in June 2018 in a collection block of plants and / or animals Tahura WAR Kelurahan Sumber Agung, Kemiling, Bandar Lampung covering 141.18 ha. The sampling intensity used was 2.30%, data collection was carried out in eight FHM cluster clusters. Based on the results of the study there were 144 individual trees that were damaged. The location of damage occurs mostly in the roots and the lower part of the stem is 29%, the lower stem is 18% and the branches are 15%. There were 11 types of damage observed with the largest type of damage, namely open wounds by 46%, broken or dead branches by 17%, cancer by 9% and leaves, shoots or shoots damaged by 9%. The most severe severity is found in the severity of 20% with a percentage of 39%, severity of 30% with a percentage of 35% and severity of 40% with a percentage of 7%.

Abstract

Rubber (Hevea brasiliensis) is a tree species developed in community forests because it has dual benefits in the form of wood and sap. Therefore, the condition of damage to rubber trees needs to be known as a support effort to produce high sap production and the health of smallholder rubber plants. This study aimed to determine the index value of rubber tree damage in the community forest of Ujung Gunung Village, Menggala District, Tulang Bawang Regency. Data collection is done by calculating the tree damage index value through the damage location parameters (X), type of damage (Y), and the severity of tree damage (Z) using a circular plot with a radius of 17.95 cm following the annular plot in the FHM cluster plot design. The results showed that from 111 samples of observations, the index value of tree damage was in the range of 1.2 – 5.5. The damage index includes damage to the rootstock, upper and lower stems, branches, and leaves with cancer damage type, damaged leaves, and dead branches. The location of the dominant damage occurred in leaves with the type of leaf damage, shoots, or shoots damaged with damage index values ranging from 1.2 - 1.9. However, the most significant damage index value occurred in tree damage with the location of the damage on the trunk, type of cancer damage with a severity level of 57%. Thus, the location of the trunk with the type of cancer damage significantly affects the tree's damage with the highest damage index value of 5.5, which can stop the tree from producing latex until death. Control measures can be taken by cleaning the remaining latex and applying fungicides to the stems. In addition, tapping that is organized and does not exploit can prevent damage to the stems.
