Penyimpanan Karbon pada Tegakan Pinus merkusii dan Acacia auriculiformis di Hutan Lindung Mangunan, Dlingo, Bantul, Daerah Istimewa Yogyakarta
Abstract: Tropical forests have roles in storing
carbon. Plant stored carbons as biomass in plant organs (roots, woods, stems
and leaves). Carbon is also stored in the litter and soil organic matter.
Carbon sequestration by stand or forest can reduce carbon emissions which
causes global warming. This research aims to study the abundance of species of
tree, sapling and seedling growthform. It also aims to estimate biomass and
carbon content in the Acacia and Pine stands. This study was conducted on
January-March 2015 in Protection Forest Mangunan, Dlingo, Bantul,
Yogyakarta. The research
consists of two
stages: species abundance
measurement in both stands, height and diameter measurements
of tree and sapling in stands. This
study used the quadratic plot method (10 x 10 m2), which consists of 5 plots in
each stand. Furthermore, data of tree height and diameter is used to estimate
carbon stocks in Acacia and Pine stands. Carbon stocks calculation using
allometric formula from Heriyanto et
al. (2005) for
Pinus merkusii and
from BPKH Wil.
XI and MFP
II (2009) for
Acacia auriculiformis. From this study it is known that in Acacia stand
there are 8 species, whereas in the Pine stand there is
only one species,
Pinus merkusii (density
1,160 ind/ha). The
most abundant species
in the tree growthform in
Acacia stand is
Acacia auriculiformis (density
380 ind/ha), in
the sapling growthform
is Voacanga grandifloria (density
520 ind/ha) and in seedling
growthform is unidentified
species (density 29,600 ind/ha).
Biomass and carbon content in the Acacia stand
(1172.70 ton/ha and 586.35 tC/ha) is higher than the
Pine stand (884.62
ton/ha and 442.31
tC/ha). The ability
carbon sequestration in
Acacia stand is higher than Pine stand.
