Taksiran Akumulasi Biomassa atas Permukaan pada Eksperimen Restorasi Lahan Gambut Bekas Terbakar, Area Transisi Cagar Biosfer Giam Siak Kecil-Bukit Batu, Riau, Sumatera Indonesia
Abstract: The Giam Siak
Kecil-Bukit Batu Biosphere Reserve was managed by zonation as a approach for
multibenefitof management goals. This Bioshere Reserve has a fairly high carbon
stock stored in its naturalpeat swamp forest ecosystems. Nevertheless, the
condition of the peat swamp forest in the BiosphereGiam Siak Kecil-Bukit Batu currently
has been destructed, especially in the buffer and transition zones.The threats
of protected areas are not only coming from forest fire factors, but also from
encroachmentand illegal logging. Therefore, it requires a recovery effort. This
research aims to determine the survivalrate and to estimate the above ground
biomass accumulation of the main tree species of peat swamp forestthat used to
restore the burnt peat. The estimated total biomass accumulation on the surface
was measured using allometric equations. Result of this research proved that
Jelutung tree (Dyera polyphylla) has thebest survival rate among the trees
(98%), while banana tree (Mezzettia parviflora) has lower survival rate( 35%).
The highest total biomass accumulation was found in Jelutung (Dyera polyphylla)
(499.015kg/ha/year, while the lowest total biomass accumulation was found in
Meranti batu (Shorea uliginosa)(88.867 kg/ha/year). A total of nine pioneer
species were identified i.e. Tenggek burung (Euodia sp),kayu ara (Ficus sp), mahang
(Macaranga triloba), karet (Havea brasiliensis), sendayan (Scleriasumatrensis),
alang-alang (Imperata cylindrica), senduduk (Melastoma malabathricum),
paku-pakuan(Neprolepis hirsutula) and rumput teki (Cyperus rotundus). The total
biomass accumulation of earlysuccession in all types of vegetation pioneer is
338,91 kg/ha.
