However, the carbon stock and sequestration potential in a mixed dipterocarp tropical forest remains unclear due to a lack of information. This study was carried out on the carbon stock and estimated its economic value to justify its conservation. Six plots were established in the Endau Rompin National Park, Johor and subplots measuring 50 × 20 m were established in each plot. All trees greater than 15 cm DBH (diameter at breast height) were identified and the parameters measured included tree height and diameter. The aboveground carbon (AGC) content was about 222 Mg(C) ha-1 , belowground carbon (BGC) was 53 Mg (C) ha-1 and it was 6 Mg (C) ha-1 for other components. In total, the carbon stock amounted to 281 Mg (C) ha-1. On the other hand, the total CO 2 sequestrated in the mixed dipterocarp forest amounted to 1,040 t CO 2 ha-1. The carbon value was estimated at RM32,240 t CO 2 ha-1 or $7,280 t CO 2 ha-1. Therefore, the study found that the dipterocarp forest should be preserved to mitigate greenhouse gas emissions. ABSTRAK Degradasi hutan dan penyahhutanan merupakan masalah global utama kerana ia boleh menurunkan penyimpanan karbon hutan dan kapasiti pensekuesteran. Walau bagaimanapun, penyimpanan karbon dan potensi pensekuesteran dalam hutan tropika dipterokarpa campuran masih tidak jelas kerana kekurangan informasi berkaitannya. Kajian ini dijalankan ke atas simpanan karbon dan anggaran nilai ekonominya untuk memberi justifikasi pemeliharaannya. Enam plot diwujudkan di Taman Negara Endau Rompin, Johor dan subplot berukuran 50 × 20 m diwujudkan di setiap plot. Semua pokok yang lebih tinggi daripada 15 cm DBH (diameter aras dada) telah dikenal pasti dan parameter yang diukur termasuk panjang dan diameter pokok. Kandungan karbon atas tanah (AGC) adalah 222 Mg(C) ha-1 , karbon bawah tanah (BGC) adalah 53 Mg(C) ha-1 dan 6 Mg(C) ha-1 untuk komponen lain. Secara keseluruhannya, simpanan karbon terkumpul adalah 281 Mg(C) ha-1. Sementara itu, jumlah CO 2 tersekuestera dalam hutan dipterokarpa campuran berjumlah 1,040 CO 2 ha-1. Nilai karbon dianggarkan sebanyak RM32,240 t CO 2 ha-1 atau $7,280 T CO 2 ha-1. Oleh itu, kajian ini menunjukkan bahawa hutan dipterokarpa patut dipelihara untuk mengurangkan pengeluaran gas rumah hijau.
