Abstract

Forest fragmentation is one of the major threats causing the loss of natural forests and biodiversity. We assessed the status of forest fragmentation from 2005 to 2020 in Nam Dong district, Thua Thien Hue province. Two satellite images of Landsat 5 TM and Landsat 8 OLI were used to extract the status of natural forest cover each time. GIS-based morphological spatial pattern analysis was also used to study the forest fragmentation change during the period. The results show that the natural forests decreased from 76.77% in 2005 to 73.79% in 2020, while the area of plantation forests increased significantly (16.55%). The analysis of forest fragmentation revealed an area decrease in forest edge, perforated forest, and fragmented forest, leading to the decline in the core forest. The main causes of forest fragmentation were forest encroachment and infrastructure development.
