ABSTRACT
Plant biomass represents a sink for atmospheric carbon dioxide,
which is one of the most important greenhouse gas. Eugeissona tristis (Bertam) is a common palm
species found in tropical lowland forest contributing to carbon and biomass
stock estimation. However, the species has been neglected in most studies
because of differences in sampling procedures and lack of equations. The
objective of this study was to develop an allometric equation in estimating
biomass and carbon content of Eugeissona tristis. This study was
conducted in 10 20 m × 50 m plots in Ayer Hitam Forest Reserve (AFHR).
Carbon content was estimated using carbon analyzer. The results showed AHFR contained
104 clumps/ha and distribution of E. tristis was not influenced by
slope. The aboveground biomass of E. tristis was estimated to be 0.879 t
ha-1 corresponding
to 1096 tonnes for AHFR area (0.4% from total aboveground
biomass). It contains 51% of carbon which contributes about 0.44 t C ha-1 and
548 t C for the whole area, depicting that this species contributed to the
overall carbon stock to a reasonable extent in AHFR.

ABSTRAK
Biojisim tumbuhan merupakan salah satu takungan karbon dioksida
atmosfera yang penting dalam penyelesaian masalah pemanasan global. Eugeissona tristis (Bertam) adalah salah satu
spesies palma yang biasa dijumpai di hutan pamah tropika dan salah satu spesis
yang menyumbang kepada anggaran stok karbon dan biomas. Walau bagaimanapun, ia
telah diabaikan dalam banyak kajian dan pengiraan stok karbon. Objektif kajian
ini adalah untuk membangunkan persamaan alometrik dalam menganggar biojisim dan
kandungan karbon Eugeissona tristis. Kajian ini telah dijalankan dalam
10 20 m × 50 m plot di Hutan Simpan Ayer Hitam Forest (HSAH), Puchong, Selangor.
Kandungan karbon dianggarkan menggunakan analisis karbon. Keputusan menunjukkan HSAH mengandungi
104 rumpun/ha dan pengagihan E. tristis tidak dipengaruhi oleh cerun.
Biojisim atas tanah E. tristis dianggarkan pada 0,879 t ha-1 bersamaan
dengan 1096 tan bagi kawasan HSAH (0.4% daripada jumlah biojisim atas
tanah). Ia juga mengandungi 51% karbon yang menyumbang kira-kira 0.44 t C ha-1 dan
548 t C bagi seluruh kawasan HSAH. Kajian ini menunjukkan bahawa E.
tristis menyumbang kepada keseluruhan stok karbon di HSAH.
