SFM — Kehutanan yang berkelanjutan di Hutan Tropis

SFM  –   Kehutanan yang berkelanjutan di Hutan Tropis

Kegiatan penelitian hutan tropis telah dilakukan di berbagai penjuru dunia, termasuk yang dilakukan di kawasan Hutan Pasoh di Malaysia .  Logging plot yang disurvei pada tahun 1955 dan diulagi lagi tahun 1989 .

Hasil penelitian ini menunjukkan bahwa pada tahun 1989 hutan tanaman berbeda dengan hutan alam asli dalam beberapa hal .  Plot-plot yang ditebang memiliki kepadatan lebih tinggi pohon kecil,  kelembaban udara lebih rendah , sedikit spesies mamalia dan burung , peningkatan penetrasi sinar UV , dan penurunan keanekaragaman hayati , dengan hanya beberapa spesies asli mampu beradaptasi dengan kondisi hutan perkebunan (hutan tanaman).

Hutan dapat mempertahankan rotasi penebangan 70 tahun (hanya menebang pohon di suatu lokasi setiap 70 tahun ), erosi tanah dapat diminimalkan .

Hutan sekunder hasil  reboisasi hutan tidak memiliki keanekaragaman hayati yang asli .
Sisa-sisa hutan alam memiliki keragaman spesies mamalia paling rendah.  Lebih banyak Spesies yang daerah jelajahnya luas,  yang berkeliaran di daerah yang lebih luas, tidak dapat bertahan dengan habitat yang terfragmentasi menjadi daerah-daerah kecil . Sebagian besar spesies dapat bertahan dalam satu siklus penebangan , tetapi kemudian jumlah populasinya berubah . Spesies minoritas menyukai penebangan dan populasinya meningkat .
Hutan harus dikelola untuk menyeimbangkan habitat satwa liar ,  produksi kayu dan produksi non – kayu , zona konservasi , pengembangan adat dan ekowisata .
Hutan Hidup mungkin bernilai jauh lebih besar daripada nilai kayunya. Pemerintah perlu mengevaluasi biaya dan manfaat hutan , termasuk fasilitas rekreasi dan pariwisata . Beberapa zonasi tata guna lahan mungkin berguna untuk melestarikan ekosistem .
