Mapping the tree damage index: A case study on the green lane in the urban area of Banda Aceh City

Abstract

Climate change mitigation efforts implemented by the Government of Banda Aceh by building green lanes with trees. The level of the tree’s ability to absorb carbon is highly correlated with the vitality of the tree itself. The health status of a tree can be known by the tree’s damage level. The aim of the research is to provide information on how much damage to trees and the degree of severity. The research was carried out on green lanes on urban streets in Banda Aceh City as many as 8 lines. The object of research is vegetation with the tree growth phase category, and tree damage index assessment using the forest health monitoring method with indicators of tree damage conditions with parameters of damage location code, damage type code, and damage level code. Based on the results, most of the trees suffered light damage. Of the total number of trees observed, there were 1797 individuals, 252 trees were in good health, 1494 were lightly damaged, 40 trees were medium damaged and 11 trees were heavily damaged. The type of damage experienced was dominated by 46% open wound, 32% cancer, 11% brum (excessive branching) and 11% the rest with other kinds of damage.
