Penelitian pada Kawasan Hutan Dengan Tujuan Khusus (KHDTK) (Hutan Pendidikan) ± 225,7 ha di Desa Senaru, Kabupaten Lombok Utara bertujuan untuk mengetahui potensi vegetasi dan cadangan karbon tersimpan. Tutupan alami KHDTK Senaru berubah akibat pemanfaatan kayu 1993, penanaman sengon dan mahoni 1996, penanaman gaharu 1998-2001, dan saat ini pemanfaatan dengan sistem agroforestri. Populasi dalam penelitian ini adalah areal KHDTK Senaru yang dikelola intensif oleh masyarakat (± 120 ha), yang ditentukan secara sengaja. Sampel dengan intensitas 1% dan terbagi dalam 30 plot ukuran 20x20 m ditentukan secara random sampling. Analisis data meliputi analisis vegetasi, cadangan karbon atas permukaan tanah dan karbon tanah. Hasil penelitian menunjukkan bahwa terdapat 32 spesies. Pada tingkat semai, pancang, tiang dan pohon ditemukan masing-masing 10, 8, 17 dan 20 spesies. Dua spesies dengan Index Nilai Penting (INP) tertinggi untuk semai dan pancang adalah kopi dan kakao, dengan INP pada tingkat semai sebesar 120,3 dan 34,2 dan pada tingkat pancang sebesar 146,1 dan 92,5. Dadap dan sengon memiliki INP tertinggi pada tingkat tiang dan pohon, dengan INP pada tingkat tiang sebesar 77,9 dan 48,7, dan pada tingkat pohon sebesar 87,1 dan 79,9. Cadangan karbon rata-rata 126,41 ton/ha, yang terdiri atas karbon tingkat pancang (3,36 ton C/ha), tiang (9,32 ton C/ha), pohon (70,61 ton C/ha), tumbuhan bawah tegakan (0,13 ton C/ha), seresah (0,29 ton C/ha) dan tanah (42,7 ton C/ha). Hasil penelitian dapat menjadi masukan dalam pengembangan model pengelolaan KHDTK Senaru dan bahan evaluasi di masa mendatang, dan secara umum dapat menambah informasi sumberdaya hutan yang sudah ada saat ini. Katakunci : hutan, vegetasi, cadangan karbon, Senaru Lombok A Study on the Vegetation and Carbon Stocks of the Special Purpose Forest (KHDTK) of Senaru Village, Northern Lombok Abstract Study was conducted in Forest for Special Purpose (Education Forest) ±225.7 ha in Senaru Village, North Lombok. The study was aimed to determine the potential of vegetation and carbon stocks. Land cover of study area was changed due to the timber management in 1993, planting mahogany and sengon in 1996, planting Aquilaria spin 1998-2001, and currently the implementation of agroforestry. Population for this study was the area of education forest intensively utilized by farmer (±120 ha). Sampling was determined by means of random with the intensity of 1% and distributed into 30 plots of 20x20m. Data analysis included analysis of vegetation, above ground carbon and soil carbon stock. The result shows that 32 species were found. There were 10, 8, 17 and 20 species of vegetation for seedlings, saplings, poles and trees, respectively. The first two highest Important Value Index (IVI) for seedling and saplings were Coffea sp and Theobroma sp, where the IVI for seedling was 120.3 and 34.2, while for saplings were 146.1 and 92.5. Erytrhina sp and Pharaseriantes sp were the two highest IVI for poles and trees, where the IVI for poles was 77.9 and 48.7, while for trees was 87.1 and 79.9, respectively. Carbon stock of study area was 126.41 ton C/ha, which was differentiated into carbon stock for saplings (3.36 ton C/ha), pole (9.32 ton C/ha), trees (70.61 ton C/ha), understory (0.13 ton C/ha), litter (0.29 ton C/ha) and soil (42.7 ton C/ha). The results of this study could be an input in develoving a model of Senaru educational forest as wells as future evaluation. Besides, it could enrich the existing information about forest resources.
