Peat swamp forest concessions and managements in Central Kalimantan have caused forest degradation resulting in the occurrence of forest fragmentation. The efforts on ecosystem restoration should be made based on the characteristics of fragmented peat swamp forest. This study aimed to find out the characteristics of degraded peat swamp forest assessed from the indicators of tree species diversity, community structure, and species dominance as well as their relationships with environmental conditions in various situations of fragmentation. The diversity of tree species tends to decrease following disturbance gradient, where the lowest was found near the edge. The community structure of the forest edge was dominated by small stand (diameter class of 6-10 cm) and dominated by Combretocarpus rotundatus of 60%. This condition was affected by environmental factors (67,2% - 71,8%): competition, site condition, microclimate and inundation.Keywords: disturbance characteristics; peat swamp forests; diversity; environmental factorsPengusahaan dan pengelolaan hutan rawa gambut selama ini di Kalimantan Tengah ternyata menyebabkan kerusakan yang menyebabkan hutan rawa gambut terfragmentasi. Usaha perbaikan ekosistem tersebut harus berdasarkan pada karakteristik dari ekosistem hutan rawa gambut yang terfragmentasi tersebut. Tujuan dari penelitian ini adalah untuk mempelajari karakteristik hutan rawa gambut terdegradasi yang terdiri dari indikator keanekaragaman jenis pohon, struktur komunitas, dan dominansi jenis serta hubungannya dengan kondisi lingkungan yang dilihat pada berbagai kondisi fragmentasi. Keanekaragaman jenis pohon semakin jauh dari hutan semakin rendah begitu juga dengan jumlah jenis dan kerapatan vegetasinya. Struktur komunitas pada bagian tepi hutan didominasi oleh tegakan berukuran kecil (kelas diameter 6-10cm) dan dominansi jenisnya hanya terpusat pada sedikit jenis dimana jenis Combretocarpus rotundatus mencapai 60%. Kondisi tersebut dipengaruhi oleh faktor lingkungan (67,2% - 71,8%) yaitu kompetisi dan kondisi lahan serta iklim mikro dan tinggi muka air tanah (genangan).Kata Kunci : karakteristik kerusakan; hutan rawa gambut; keanekaragaman; faktor lingkungan

Reinwardtia 19(1): 27‒54. ‒‒ Most peat swamp forest has been degraded. This has resulted in decline of its biodiversity. The objective of this study was to identify the composition, diversity, and plants used by local people in Bagantung swamp forest. The study was conducted on degraded peat swamp forest area in Bagantung, Mantangai Sub-District, Kapuas District, Central Kalimantan Province. The Shannon-Wiener (H’) and the Importance Value (IV) indices were used for analyzing the species diversity and the species importance across a number of forest plots. Useful tree species were identified by interviewing local villagers. There were 2,562 individual plants in 32 plots (each plot 20 m × 20 m). We identified 100 tree species and 16 non-tree species, from 74 genera, and 46 families. Myrtaceae, Sapotaceae, Ebenaceae, Dipterocarpaceae and Clusiaceae were the most dominant families. Large tree (H’=1.46) and small tree diversity was similar (H’=1.75). In both small and large tree size classes Calophyllum nodusum was the most dominant species. There were 16 tree species and two non-tree species used by local people for house and boat construction, furniture, handicrafts, medicine, and insect repellent.

Peat swamp forest is a particularly stable ecosystem. This stability may regulate well-balanced water to maintain the existence of typical flora and fauna. The present study describes the structure and species composition from three different sites namely newly logged-over swamp forest, three years old logged-over swamp forest, and four years old-logged over swamp forest in Bengkalis, Riau, Indonesia. The study sites were predominated by four structural ensembles with their strata order from the highest to lowest: emergent trees, canopy, lower ensembles, and undergrowth. The emergent trees consisted of three tree species, and the canopy included four species, lower groups covered three species, and undergrowth had two species. Overall, the three sites composed of 26 species with 24 genera and 24 families. Dendrogram based on similarity of site index showed that newly and three years old logged-over forest joined into one cluster with Euclidean distance at 38.42. Furthermore, both sites joined with four years old logged over forest forming another cluster with 489.19 Euclidean distances. Present study, therefore, showing that four years old logged-over peat swamp forest turned out to have the greatest Euclidean distance value.

<p>The aim of the study was to evaluate the growth performance of three indigenous tree species planted under open area planting technique of burned area at Klias Peat Swamp Forest, Beaufort, Sabah. Three indigenous tree species was used in this study, namely are <em>Cratoxylum arborescens</em> (Vahl) Blume (Geronggang), <em>Alstonia spathulata</em> Blume (Pulai), and <em>Stemonurus scorpioides</em> Becc. (Katok). A total of 45 seedlings for each species were examined using Randomized Complete Block Design (RCBD) with spacing of 3mx3m. Data collection for height, diameter, and survivality was recorded every two weeks within 10 weeks period from the seedlings was planted. Results from this study showed, the growth performance of Geronggang species was much better than the Pulai species, while all the Katok seedlings were died after week 6 in this experiment. The Geronggang species had the average mean height increment of 24.17 cm and average mean diameter increment of 2.76 mm, while Pulai species had average mean height increment of 9.36 cm and average mean diameter increment with 1.86 mm. For the survivality results, it showed that the Geronggang species had the highest survivality rate at 93.33% and Pulai species with 86.67%. There was a significant difference in term of relative height growth rate between Geronggang and Pulai species.  However, there was no significant difference in term of relative diameter growth rate at significant level of P ≤ 0.05. The findings indicates that Geronggang and Pulai are suitable to be planted at burned area in Klias peat swamp forest for the purpose of reforestation using open area planting technique, while the Katok species is not suitable due to environment consideration. The better growth performance of the Geronggang and Pulai species are because they can easily adapted with the open area planting at the study site.</p>

Abstract Peat swamp forests in Southeast Asia are under heavy pressure. Deforestation, forest degradation, wildfires, and drainage have damaged or destroyed substantial areas of the once extensive peat swamp forest formations. Several efforts are underway to rehabilitate degraded peat forests areas in order to restore some of the valuable ecosystem services these forested areas once provided. However, these efforts often result in (mixed)-plantations that only partly resemble the original peat forests. Information about these peat swamp forests’ complex origin and ecology is needed to improve restoration outcomes further. Our paper analyses historical data from coastal peat swamp forests in Sarawak and Brunei and discusses the potential to use this as the reference value for intact peat forests. We describe the observed stand structure and species composition for pristine peat swamp forest, and we analyze the population structure of three dominant peat swamp forest species: Gonystylus bancanus (ramin), Dactylocladus stenostachys (jongkong) and Shorea albida (alan batu). We compare the historical data with data from recently measured, degraded peat swamp forests. We discuss our results in relation to processes of peat dome formation, nutrient availability and hydrology, and give recommendations for peat swamp forest management and restoration.
