Reduced Impact Logging

Saat ini, kegiatan pemanenan kayu di hutan alam lebih efisien dengan diterapkannya teknik pembalakan berdampak rendah (reduced impact logging, RIL). Pemanenan kayu yang lebih efisien akan mengurangi terjadinya limbah yang berakibat meningkatkan angka standar faktor eksploitasi (FE). Ironisnya hingga kini angka standar FE yang ditetapkan oleh Kementerian Lingkungan Hidup dan Kehutanan masih didasarkan pada cara pemanenan kayu konvensional, yaitu sebesar 0,7. Sub region Provinsi Kalimantan Tengah mempunyai peranan besar dalam menyumbang produksi kayu bulat hutan alam baik secara regional Pulau Kalimantan sebesar 61,5% dan secara Nasional sebesar 29,7%, namun belum diketahui banyaknya limbah pemanenan kayu dan besaran standar faktor eksploitasi. Tujuan penelitian ini adalah untuk mengetahui banyaknya limbah pemanenan kayu dan angka standard FE yang dilakukan oleh PBPH di sub region Kalimantan Tengah. Penelitian dilakukan di Perizinan Berusaha Pemanfaatan Hutan (PBPH) yang bersertifikat Pengelolaan Hutan Produksi Lestari (PHPL) mandatory dan PBPH bersertifikat PHPL voluntary. Hasil penelitian menunjukkan bahwa potensi limbah pemanenan kayu akibat pembagian batang di petak tebang rata-rata 0,919 m3/pohon dan besarnya limbah kayu akibat pengujian dan pengukuran di TPn berkisar rata-rata 0,093 m3/pohon. Angka FE berkisar antara 0,80-0,85 dengan rata-rata 0,82. Besar kecilnya angka FE lebih dipengaruhi oleh faktor ketrampilan penebang, kebijakan manajemen PBPH, dan diameter pohon ditebang.

Reduced Impact Logging

Avaliou-se o efeito da exploração de madeira, realizada em 1997, na estrutura e dinâmica de algumas espécies de Sapotaceae em uma Floresta Ombrófila Densa, no município de Moju, Pará (02º12’26”S e 48º48’14”W). De uma área de floresta de 1.050 ha, foram selecionados 200 hapara exploração seletiva de intensidade de 23 m3.ha-1. Nessa área, foram alocadas 22 parcelas permanentes de 0,5 ha, totalizando 11 ha amostrais, onde foram medidas todas as árvores com DAP ≥10 cm, nos anos de 1995 (antes da exploração), 1998 e 2010 (após exploração). Os parâmetros avaliados foram densidade (Da) e área basal (m2.ha-1). No período de 1995 a 2010, Sapotaceae apresentou uma redução significativa de 7,7% na densidade (p = 0,0147) e aumento na dominância em 1,4% (p = 0,7851). Nesse mesmo período, observou-se redução da densidade e dominância para Pouteria laurifolia (Gomes) Radlk. (66,7 e 50,6%), Pouteria macrocarpa (Mart.) D. Dietr. (25 e 29,4%), Micropholis acutangula (Ducke) Eyma (20 e 11%), Manilkara huberi (Ducke) A. Chev. (16,4 e 17,7%) e Manilkara paraensis (Huber) Standl. (12,5 e 31,4%). A espécie com maior valor comercial, M. huberi, não mostrou recuperação nesse parâmetro, porém houve ingresso de três novas espécies na população de Sapotaceae estudada.AbstractEffect of reduced impact logging in some sapotaceae species in the eastern amazon. Effect of logging, held in 1997, on structure and dynamics of some Sapotaceae species were evaluated in a dense tropical rain forest located in the municipality of Moju, Pará (02º 12’ 26” S e 48º 48’ 14” W). Two hundred ha out of 1,050 ha forest area were selectively logged for timber (23 m3ha-1 logging intensity) in 1997.Twenty-two 0.5 ha permanent sample plots (11 ha sample) were established and all trees with dbh ≥ 10 cm were identified and measured for dbh in 1995 (before logging), 1998 and 2010 (after logging). Parameters evaluated were Density (De) and Basal area (G-m2 ha-1). Sapotaceae presented a significant reduction of 7.7% on tree density (p=0.0147), and an dominance increase of 1.4% (p=0.7851). In the same period, decreases in density and basal area were observed to Pouteria laurifolia (Gomes) Radlk. (66.7 and 50.6%), Pouteria macrocarpa (Mart.) D. Dietr. (25 and 29.4%), Micropholis acutangula (Ducke) Eyma (20 and 11%), Manilkara huberi (Ducke) A. Chev. (16.4 and 17.7%) and Manilkara paraensis (Huber) Standl. (12.5 and 31.4%). The main commercial species M. Huberi did not recover its original density. On the other hand, three new species of the family were recorded in the focused period.Keywords: Forest management; Pouteria; Manilkara; Amazonian Forest.
