Comparison of Crown Health Assessment Using Forest Health Monitoring and Remote Sensing Techniques (Case Study: KTH Lestari Jaya 8, KPHL Kota Agung Utara, Lampung)

Abstract

Tree crown is one of the main components that must be monitored to assess the health condition of the forest. The crown condition is described by five ecological parameters namely : live crown ratio, foliage transparency, crown density, crown diameter, and the dieback. The method used to assess the canopy condition was the Forest Health Monitoring (FHM) method and remote sensing with the Normalize Difference Vegetation Index (NDVI) transformation.. This study was conducted with the aim of being able to determine the condition of tree crown in protected forests using the FHM and remote sensing methods so that a comparison of the assessment results of the two methods can be carried out. This research was carried out at HKm Beringin Jaya, a managed area of KTH Lestari Jaya 8 which is located in Sumberejo District, Tanggamus Regency. The results of this study are that the Visual Crown Ratio value obtained ranges from 2.50 - 3.25. NDVI value describing the condition of the tree crown ranges from 0.75-0.83. The conclusion obtained from this study is that with the FHM technique, the health condition of the tree crown obtained is moderate to good, while with remote sensing techniques, the condition of the tree crown is in a very good condition.
