PENGARUH STRUKTUR DAN KOMPOSISI TEGAKAN TERHADAP CADANGAN KARBON TUMBUHAN BAWAH DI HUTAN DESA SIMORANGKIR JULU, KABUPATEN TAPANULI UTARA
ABSTRACT: The utilization of
forest which not offset by maintenance and care efforts will lead to the
destruction of forests so that increase carbon levels in atmosphere. All
components of the vegetation either trees, shrubs, lianas and epiphytes,
groundcovers are carbon sink. However, the growth of groundcover very strongly
influenced by the structure and composition of stands. Measurements of carbon
groundcover in this village forest needs to determine the value of the
importance of forests to be carbon sink as part of efforts to mitigate climate
change in the North Tapanuli District. The purpose of this research was to
analyze stand structure and composition and calculate groundcover carbon stocks
in forest of Simorangkir Julu Village. Object of this research is the stand and
groundcover in the forest of Simorangkir Julu Village. The method used is
analysis of vegetation at the stands and
groundcovers. Destructive sampling method were used to harvest groundcover in 2
m x 2 m sample plots for carbon analyze. Then, followed by analysis of effect
the structure and composition stands to groundcover carbon. The results of this research indicate that
there were 26 species of groundcover. Carbon stock of groundcover in salagundi
stand is 4.93 tonnes/ ha, and in pine stand 4.88 tonnes/ ha. Based on statistical analysis of carbon stocks
groundcover in pine stands and Salagundi stands not significantly different.
Carbon stocks are
more influenced by the diversity
and density of groundcover, soil
type, and environmental condition.
