Forest composition and carbon reserves in Bukit Barisan Forest Park, Dolat Rayat Village, Karo District

Abstract

Bukit Barisan Grand Forest Park Forest is a forest area formed from forests with protected forest status. In this forest area there is a main road connecting the cities of Medan and Berastagi, which is a tourist destination for people in North Sumatra. Therefore this area is very unique to study but is also vulnerable to logging disturbances, etc. Apart from that, tourist activities also put pressure on this area, especially during holiday periods. The aim of this research is to determine the composition of stands and the carbon content stored in Dolay Rayat Village, Karo Regency. The method used is a combination of stripes and plotted lines where the plots are placed using systematic sampling with random start. Meanwhile, allometric equations are used to estimate carbon stocks. The research used 50 sample plots (2 Ha) arranged in 10 transect lines. The results of the vegetation analysis that has been carried out show that there are 29 types of standing vegetation. The dominant species found at the seedling level are Eurya accuminata (IVI: 30.05), saplings are Altingia excelsa (IVI: 34.44), poles are Lithocarpus edulis (IVI: 44.61) and trees are Lithocarpus edulis (IVI: 30.82). This forest has moderate species diversity with an H’ value ranging from 2.41-2.76. Carbon reserves stored in forest areas in the administrative area of Dolat Rayat Village are quite high, namely 14,639.04 tons.
