"Penelitian dilakukan pada masyarakat lokal Dayak Lundayeh dan Uma? lung di Kabupaten Malinau Kalimantan Timur. Tujuan penelitian ini adalah untuk mengumpulkan data tentang keanekaragaman tumbuhan Hasil Hutan Nonkayu (HHNK) dan untuk sumber daya hayati dari perspektif lokal. Data dikumpulkan dari bulan Oktober 2010 sampai dengan Januari 2011 dengan menggunakan metode wawancara untuk mengumpulkan semua informasi tentang keanekaragaman tumbuhan HHNK dan penggunaan oleh masyarakat lokal berdasarkan persepsi mereka sendiri. Metode Multidisciplinary Landscape Assessment (MLA) telah digunakan secara intensif untuk mengidentifikasi nilainilai relatif spesies tumbuhan berdasarkan persepsi masyarakat. Untuk mengetahui sistem pengetahuan masyarakat lokal adalah dengan menganalisa nilai kepentingan budaya (ICS). Berdasarkan wawancara dengan masyarakat setempat, pemanfaatan keanekaragaman jenis tumbuhan HHNK yang didokumentasikan dalam penelitian ini adalah untuk bahan pangan (109), bahan obat-obatan (183 spesies), bahan ritual (3 spesies), bahan kerajinan dan teknologi lokal (25 spesies), bahan racun dan anti racun (23 spesies), bahan pewarna (9 spesies) dan kayu bakar (11 spesies). Berdasarkan hasil perhitungan MLA, untuk setiap kategori kegunaan menunjukkan nilai pemanfaatan kepentingan jenis bahan pangan sebesar 5,32%, sayuran 4,9%, buah-buahan 3,74%, bahan obat-obatan 2,84%, teknologi lokal 7,5%, bahan racun dan anti racun 7,5%, bahan pewarna 1,98% dan kayu bakar 4,86%. Nilai tersebut menunjukkan bahwa seluruh jenis tumbuhan yang diketahui, telah dimanfaatkan masyarakat sebesar 38,64%. Untuk hasil ICS, nilai tertinggi adalah Eusideroxylon zwageri dengan nilai 65 dan pemanfaatan tumbuhan tertinggi adalah untuk tujuan medis (obat-obatan).

The study was conducted in the village of Dayak Lundayeh and Uma? lung in East Kalimantan. The aim of this study is to collect data on Non Timber Forest Products (NTFPs) plant use diversity and to know local knowledge system of Dayak Lundayeh and Uma' lung. The data was collected from October 2010 to January 2011 using interview method to gather all information on plant diversity and it usage by the local society based on their own perception. The method of Multidisciplinary Landscape Assessment (MLA) has been used intensively to identify relative values of plant species based on the community perception. To know local knowledge system of NTFPs is by analyzing the value of cultural interest or Index of Cultural Significance (ICS).

Based on interview with local society, utilization of NTFPs species diversity documented in this study are for, primary food (2 species), secondary food (109 species), medicine (183 species), craft materials and local technology (25 species), ritual ceremony (3 species), toxic substances and anti-poison (23 species), dyes (9 species) and firewood (11 species). The result indicated that local people utilizing plants is for primary foods (5,32%), vegetables (4,9%), fruits (3,74%), medicinal plant (2,84%), local technology (7,5%), toxic substances and anti poison (7,5%), dyes (1,98%) and firewood (4,86%). The total amount of utilizing plants is 38,64%. The results of the highest value ICS is Eusideroxylon zwageri with a value of 65 and the highest plant utilization is for medical purposes."

"Acacia catechu (Sha)-bearing forests are the primary sources of cutch, a tannin extract from the heartwood of Sha trees. Sha forests in Myanmar are managed for cutch production, and tree harvesting for cutch is regulated by an official diameter limit (ODL, 30 cm DBH [diameter at breast height]). We explored sustainable Sha forest management for cutch production through stand inventory surveys and informal interviews with locals and forest managers. We compared Sha forests with six different official harvest histories and assessed seedlings and saplings as well as the size and species of harvested stumps and remaining trees. We found that the forest understory was disturbed by surface fire, and all Sha seedlings and saplings < 1.7 m in height showed post-fire marks. We observed a regeneration gap between 1.7 m and 2.7 m, which might indicate the flame height of the surface fire. The “illegal” harvest exceeded the official harvest; only 5% of the harvested stumps were found to be larger than the ODL. Local harvesting of cutch appeared to be limited by the stem diameter required for heartwood formation (15 cm DBH). Stump data revealed that the forests were utilized not only for cutch but also for other purposes, including fuel and timber. Despite fire and local harvesting, local forest utilization patterns appear to be reasonable, although they are illegal. Implementing fire control and community management of forests along with clear definition of property rights could help in sustainably managing Sha forests for cutch production."
