"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."

"The contents also highlight efforts to conserve and promote traditional forest management practices that balance the environmental, economic and social objectives of forest management. It places these efforts in the context of recent trends towards the devolution of forest management authority in many parts of the world.The book includes regional chapters covering North America, South America, Africa, Europe, Asia and the Australia-Pacific region. As well as relating the general factors mentioned above to these specific areas, these chapters cover issues of special regional significance, such as the importance of traditional knowledge and practices for food security, economic development and cultural identity. Other chapters examine topics ranging from key policy issues to the significant programs of regional and international organisations, and from research ethics and best practices for scientific study of traditional knowledge to the adaptation of traditional forest knowledge to climate change and globalisation."

ABSTRACTAnalysis of the composition, structure, and tree regeneration of the lowland forestin the eastern part of the core zone of the Bukit Duabelas National Park, Jambiwas conducted in October and November 2012. The study was carried out on aone-hectare plot laid out on a slope of a lowland hill forest. A total of 100quadrats of 10 m x 10 m each was used to obtain data trees, and plots measuring 5m x 5 m and 1 m x 1 m each were nestled in sapling quadrates to secure data ofsaplings and seedlings. We recorded 414 trees with diameter at breast height(DBH) ≥ 10 cm, representing 113 species of 38 families, with the total basal area(BA) of 25.71 m2 and Shannon--Wiener diversity index of 4,29. A total of 282individuals were recorded representing 88 species of 34 families at the saplingstage and 222 individuals of seedlings representing 67 species of 32 families. Theprevalent species of tree was Prunus arborea with Importance Value (IV) of19.2%. Ficus fistulosa was the tree species with the highest density (24 trees/ha).The highest density of seedlings was Rinorea anguifera (24 trees/ha) and thehighest density of saplings was Ficus fistulosa (15 trees/ha). Moraceae with IV34,05% was dominant in the study site at tree stage, while Violaceae andBurseraceae with each IV 28.31% and 25.67% were dominant at seedlings andsaplings stage. A total of 71 species or 62.8% of all tree species wereregenerating in the plot. Based on the density of seedlings, saplings and trees, thespecies of Euphorbiaceae showed a good regenerating capability and expected tobe the dominant family in the future in the area. A total of 61 species areregistered in the Sumatra checklist and one of them is endemic, which wasBaccaurea dulcis. Following the IUCN redlist we categorized Shorea leprosulaas an endangered species, Aquilaria malaccensis as a vulnerable species, and 12others as species with low risk."

"Hutan mangrove tergolong sumberdaya hutan yang mempunyai peranan penting bagi pernbangunan Nasional. Hal ini karena lokasinya yang strategis dan potensi yang terkandung di dalamnya, serta fungsi perlindungannya yang secara langsung ataupun tidak langsung mempengaruhi eksistensi dan berfungsinya sumberdaya alam lain.Ekosistem ini dicirikan oleh produktivitasnya yang tinggi dan daur nutrisi yang cepat, sehingga mangrove dianggap penyedia nutrisi bagi kontinuitas sebagian besar energi yang diperlukan oleh berbagai biota akuatik di ekosisitem pantai. Ekosistem ini juga berperan sebagai pendukung eksistensi lingkungan fisik, yaitu sebagai penyangga abrasi pantai oleh gelombang, intrusi air laut ataupun hembusan angin yang dapat merusak ekosistem darat.Pertambahan jumlah penduduk yang semakin meningkat dan pesatnya perkembangan teknologi mengakibatkan tekanan terhadap keberadaan hutan mangrove. Pemanfaatan tidak saja dilakukan dalam bentuk pengambilan hasil hutan, tetapi berkembang ke bentuk pemanfaatan lahan mangrove.Pulau Bengkalis adalah satu diantara enam pulau yang ada di Kabupaten Bengkalis yang mempunyai hutan mangrove rnencapai 15.039 ha tersebar mengelilingi pulau. Wilayah hutan mangrove yang mengalami tekanan cukup berat berada di wilayah pantai utara yang berbatasan dengan Selat Malaka Luas hutan mangrove di wilayah tersebut mencapai 9.133 ha. Secara ekologis lingkungan fisik wilayah tersebut mendukung untuk pertumbuhan dan perkembangan hutan mangrove. Terdapat tiga aliran sungai yang bermuara di di Pantai Utara Pulau Bengkalis, dan menjadi sumber aliran air tawar. Kandungan lumpur (sedimen) berkisar antara 5%-85%, bahan organik 50%, salinitas 26-32 ppm. Keadaan laut, tenang sampai agak kuat yang tinggi gelombangnya antara 0,4 sampai 2,7 m dengan kecepatan 0,1-5 knot. Kondisi lingkungan alami tersebut selayaknya mendukung kelestarian hutan mangrove. Namun demikian, akibat pemanfaatan yang tidak terkendali dan sudah berlangsung lama, mengakibatkan terjadinya kerusakan hutan mangrove, sehingga menurunkan fungsinya sebagai pelindung pantai akibat abrasi. Terjadinya kerusakan hutan mangrove dan abrasi belum menjadi perhatian serius bagi masyarakat dan pemerintah, sekalipun dampaknya sudah dirasakan. Atas dasar permasalahan tersebut, rumusan yang perlu untuk dijawab adalah 1). Seberapa besar kerusakan hutan mangrove yang terjadi; dan 2). Seberapa besar abrasi di Pantai Utara Pulau Bengkalis; serta 3). Adakah hubungan kerusakan hutan mangrove dengan abrasi yang terjadi.Penelitian ini bertujuan untuk mendapatkan informasi kerusakan hutan mangrove dan hubungannya dengan abrasi yang telah terjadi. Hasil penelitian ini diharapkan dapat memberi masukan kepada perencana dan pengambil keputusan, khususnya Pemerintah Kabupaten Bengkalis dalam penyempurnaan, maupun pembuatan kebijakan tentang pengelolaan hutan mangrove yang ada di daerah penelitian atau kawasan lainnya. Hopotesis yang diajukan adalah bahwa semakin tinggi tingkat kerusakan hutan mangrove akan mengakibatkan semakin tinggi abrasi yang terjadi di Pantai Utara Pulau Bengkalis.Hasil penelitian memperlihatkan bahwa komposisi jenis mangrove di wilayah Pantai Utara Pulau Bengkalis terdiri dari 9 spesies jenis pohon. Jenis yang dominan adalah api-api (Avicennia marina), bakau (Rhizophora mucronata) dan lenggadai (Bruguiera cylindrica). Kerapatan individu setiap hektarnya pada strata anakan mencapai 1.897 pohon, sedangkan strata pancang 1.341 pohon dan strata pohon hanya 849 phn/ha.Pemanfaatan hutan mangrove oleh masyarakat meliputi pengambilan kayu untuk bangunan/pancang, bahan baku arang, dan untuk kayu bakar serta konversi menjadi lahan tambak. Rata-rata pemanfaatan setiap tahun untuk kayu bangunan/pancang sebanyak 2.812 pohon, kayu arang 3.217 pohon dan kayu bakar untuk rumah tangga 2.444 pohon, sedangkan yang kayu bakar industri bata mencapai 7.657 pohon.Akibat pemanfaatan yang tidak terkendali, menyebabkan terjadinya kerusakan hutan mangrove yaitu menurunnya kerapatan pohon setiap tahun yang berkisar antara 0,32%-1,6% atau rata-rata 0,79%. Penurunan kerapatan pohon ini setara dengan berkurangnya pohon sebanyak 61.255 pohon setiap tahun. Kerusakan ini menyebabkan menurunnya kemampuan fisik hutan mangrove untuk menahan terjadinya abrasi. Laju abrasi per tahun berkisar antara 3,6-8,4 meter atau rata.-rata 6,03 meter. Hasil analisis memperlihatkan bahwa terdapat hubungan positif dan signitikan antara penurunan kerapatan pohon dengan laju abrasi yang terjadi.Kerusakan hutan mangrove dan terjadinya abrasi ada kaitannya dengan persepsi masyarakat mengenai hutan mangrove. Sebagian besar (5S,3 %) menyatakan hutan mangrove hanya sebagai sumber hasil hutan, dan tingkat kesadaran masyarakat untuk memelihara juga sangat rendah (4,57%), sedangkan sebagian besar (56,00%) menyadari pentingnya hutan mangrove tetapi tidak melakukan pemeliharaan.Berdasarkan kenyataan ini perlu adanya upaya rehabilitasi hutan mangrove, sekaligus meningkatkan sumberdaya manusia agar pengetahuan dan partisipasi masyarakat sehjngga upaya pelestarian fungsi hutan mangrove dapat meningkat.

Mangrove forests has a very strategic locations, many potentials and great protective functions that bring them to be one of forest resources that play important role for the nation development. Its protective functions have a strong influence to the existence and the function of other resources, directly or indirectly.This ecosystem is characterized by its high productivity and fast nutrient cycle made it become the nutrient source for the most energy supply need by varies aquatic biota in coastal ecosystems. Mangrove ecosystem also functioned as physical environment existence support to protect the coast from abrasion, restrain seawater intrusion and strong wind that can ravage terrestrial ecosystems.The fast growth of population and high technology development has lead to a high pressure on mangrove forests existence. The exploitations of mangrove forest resources are not only done by reaping its product but as well as exploit its land.Bengkalis Island as one of six islands in Bengkalis District has a 15.093 ha mangrove forests spreading along its coastal area. Mangrove forests at the north coast, bordered on Malacca Strait, are the one received high pressure. Its area occupied 9.133 hectare area. Ecologically, its physical environment supports the growth of that mangrove forest. There are three rivers ending in Bengkalis Island North Coast that become the source of fresh water. The sediment content of those streams varies between 5% to 85%, organic matter 50%, and salinity between 26-32 ppm. The sea situation is still to strong. The wave height is between 0,4 to 2,7 m with the speed of 0,1 - 5 knots. This natural condition supposed to support mangrove forest sustainability. However, uncontrolled exploitation for a long time result in the degradation of mangrove forest that decrease its function to prevent coastal abrasion Those two phenomenons haven?t got a big concem of the govemment and the community yet, even though some of its impact has been experienced. Based on those problems, there is some questions arise: I). How worse is that mangrove forest degradation?, 2). How big is the abrasion in Bengkalis Island north coast?, 3). Is there a conelation between mangrove forest degradation and the abrasion?.The purpose of this research is to gain information of mangrove forest degradation and its correlation with the abrasion. The result is expected to be a valuable input for the planner and the decision makers in Bengkalis District to make and perfecting policies on mangrove forest management, not only in the research area but also in other regions.The research showed that mangrove forest in Bengkalis Island North Coast composed 9 tree species. The dominant species are api-api (A vicennia marina), bakau (Rhizophora mucronara) dan lenggadai (Bruguiera cylindrica). The density in seedling stratum reaches 1.897 individual per hectare, while sapling stratum reach 1.341 and there are only 849 in tree stratum.People use the forest to get the log to build houses. They also use the resources as raw material to make charcoal, use it as fuel and converse the land to be used as fishpond. Average usage for building need is 2.812 trees annually, 3.217 trees converted to charcoal annually, 2.444 trees used as fuel annually, and 7.657 trees cut to supply brick indusuies.This uncontrolled use of the mangrove lead to its degradation showed by the decreasing of its density between 0,32% to 1,6% annually or 0,66% on the average. This decrease is equal to the loose of 61,255 trees annually. It also leads to the declining of mangrove forest function to prevent the land from abrasion. Abrasion rate varied between 3,6 to 8,4 meter annually or 6,03 meter on the average. The analysis showed that there is a positive and significant correlation between trees decreasing rate and abrasion rate.Mangrove forest degradation and coast abrasion are related to community perception. Most of the respondents (58,3%) stated that mangrove forest is functioned only as the source of mangrove product they need. They also have a low awareness to preserve the mangrove (4,57%). Most of them (56%) understand the important role of mangrove forest but didn?t conduct any acts to preserve it.Based on these findings, mangrove forest rehabilitation is very needed along with environmental education to develop human resources lived surrounding the forest and increase community participation to preserve functions of mangrove forest could be step up."

Mangrove forest is ecosystems that have a role in enriching aquatic conditions and protecting coastlines from abrasion and accretion. Teluk Lembar in West Lombok Regency which continues to develop into a port center on Lombok Island has caused changes in coastline and landuse. This study deals with the relations of extensive mangrove forest changes to coastline changes and landuse changes in Teluk Lembar for a period of 1995 to 2019. The purpose of this study was to determine the temporal spatial distribution of mangrove forest and analyze the relations between land use and coastline to spatial distribution temporarily mangrove forest in Teluk Lembar in the period 1995-2019. The research used Landsat 5, 7, dan 8 images which were 1995 and 2005, 2005 and 2015, and the last period was 2015 and 2019. The data were processed by calculating the area and changes in mangrove forest, coastline, and landuse. Then the extensive changes in mangrove forest are associated with extensive abrasion and accretion on coastline changes in the study area. The area of mangrove forest has increased from each year of observation. The dominant change in coastline that occurred in 1995-2019 was accretion. Changes in the use of mangrove land that underwent changes in 1995-2019 were dominated by changes in water bodies into mangroves and mangroves to become water bodies. Based on the calculation of the analysis of the relations of mangrove changes to the extent of abrasion and accretion, the increase in mangroves has a relation to accretion of 98,81%, while the decrease in mangroves to abrasion is 21,60%. Spatially, the decrease and addition of mangrove are directly proportional to the broad changes in abrasion and accretion."

"Produksi kayu bulat yang berasal dari hutan rakyat memberikan kontribusi yang positif dalam memenuhi kebutuhan pasokan bahan baku industri nasional. Sertifikasi SVLK hutan rakyat terus didorong oleh pemerintah agar tidak menjadi celah pada sistem legalitas kayu yang telah dibangun secara multi-pihak. Penelitian ini bertujuan menganalisis biaya sertifikasi SVLK hutan rakyat; menganalisis kemampuan dan kemauan membayar petani hutan rakyat; menganalisis pengaruh hutan rakyat serta manfaat SVLK terhadap pendapatan dan matapencaharian petani; menganalisis manfaat sertifikasi SVLK terhadap volume panen kayu; dan memperoleh konsep sertifikasi SVLK bagi hutan rakyat yang berkelanjutan dengan pendekatan kemampuan membayar petani. Penelitian dilakukan dengan pendekatan kuantitatif dan metode gabungan. Pengambilan data melalui kuesioner dan wawancara dilakukan kepada petani hutan, perwakilan pemerintah dan pihak swasta. Hasil penelitian menunjukkan bahwa kemampuan membayar dan keinginan membayar pada kedua KTH rendah terhadap biaya sertifikasi SVLK sehingga disimpulkan kelompok petani hutan belum mampu membayar biaya tambahan sertifikasi SVLK dalam pengusahaan hutan. Kesimpulan penelitian ini adalah kemampuan membayar terhadap sertifikasi SVLK oleh petani mempengaruhi keberlanjutan penerapan sertifikasi SVLK sehingga diperlukan dukungan dari pasar dan peran mitra.

Logs production from private forests has made a positive contribution to meeting the demand for raw material supplies for the national industry. The government continues to encourage private forest to SVLK certification so that it does not become a gap in the timber legality system that has been developed in a multi-stakeholder manner. This study aims to analyze the costs of community forest SVLK certification; analyzing the ability and willingness to pay of forest farmers; analyze the effect of SVLK certification on farmers’ income and livelihood; analyze the effect of SVLK certification on timber harvest volume; and obtaining the concept of SVLK certification for sustainable private forests using approach of farmers' ability to pay. The research was conducted using a quantitative approach and a combined method. Data were collected through questionnaires and interviews with forest farmers, government representatives and private sector. Result showed that ability to pay and willingness to pay of SVLK certification in both KTH were low, so it was concluded that private forest farmer groups not been able to pay SVLK certification as an additional cost of log business. The conclusion of this study is that the ability to pay for SVLK certification by farmers affects the sustainability of the application of SVLK certification so that support from the market and role of partners is needed."

The ownership rights honeycomb on repak, lalau, tikung are the same being as the owner, while the land and tree tenure is different, Management of the soil, tree and honeycomb on all three honey forest resources is implemented according with the institutions who prevailing in society and institutions which applicable constitute customary rules. This instituions holds an important role in the management of forest honey resources."

"This study seeks to gather empirical evidence regarding education and access to information in affecting mangrove forests in Indonesia. The motivation for this study comes from the fact that Indonesia has experienced enormous mangrove deforestation in the last three decades. This study uses village level data in Indonesia. With a combination of geospatial data and PODES, the author uses the unbalanced panel data and Fixed Effects Model (FEM) to analyze the correlation of 9-year basic education facilities and higher education as well as national private TV broadcasts and overseas TV broadcasts on the area of mangrove forests. The author found that villages that have higher education facilities and get overseas TV broadcasts have a positive correlation with the area of mangrove forests in the village area. Higher education and broad access to information globally can certainly increase villagers’ knowledge and concern about the importance of mangrove forests. Therefore, government policies are needed to improve higher education facilities and access to global information in villages to reduce the exploitation of villagers against mangrove forests, especially for village communities located around mangrove forests."
