Indigenous Tree Species

<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>

This study focuses on factors controlling CO2and CH4emission in a peat swamp forest related to water table and peat characteristics such as peat depth, C-organic, pH, ash content and N-total. This study was conducted in the dry season at a Merang peat swamp forest that has degraded due to logging activities, forest fires and canal opening. Emission of CO2and CH4was measured by using a closed chamber made by PVC material (60 cm x 60 cm x 40 cm). This close chamber was completed with a fan inside the chamber to stir the gas, a thermometer inside the chamber to measure the gas temperature and a syringe to sample gas. This study has shown that the highest CO2emission is at an average of 438.93 mg/m2/hr occurring in land cover type (1) ferns and grasses (open burned area) and the lowest is at average of 44.45 mg/m2/hr in thegelamandbelidang-dominated land. The emission of CH4is very low between 0.0018 to 0.0069 mg/m2/hr. the main controlling factor on CO2and CH4emission is concluded to be the water table. The emission of CO2will be greater if water table, pH and C-organic increase.

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.

Significant Difference

Soil of tropical forest ecosystem plays very crucial part in controlling the universal carbon cycle. The isolation of microorganisms and their identification are important for understanding their vital role on transformation of organic matter of this ecosystem. Soil storage maximum microbial genetic diversity because of it’s a multilayered environment. No complete methods were discovered yet to cultivate majority of soil microorganisms. A little is known about microbial structure and their essentiality in tropical peat lands compared to most other terrestrial and oceanic habitats. In providing insight to the impacts of land-use of peat land on microbes in Central Kalimantan, Borneo Indonesia, we examined the community structure and diversity of bacteria and fungi in different peat forest soil including: i) natural peat swamp forest (well mixed swamp forest type); ii) disturbed peat soil and iii) mineral soils by using 454 pyrosequencing technology. The results showed that no significant difference was found for diversity and evenness among the sites of fungal community. However, natural peat swamp forest had the highest species richness (Chao1), which was significantly higher than the other two sites (P<0.05 and P<0.05). According to the OTUs analysis four fungi phyla were obtained of which 45 species were classified. The Ascomycota was the most abundant phylum, followed by Basidiomycota, Zygomycota and Glomeromycota. The natural peat swamp forest and disturbed peat soil harbored the maximum number Ascomycota. On the other hand, mineral soil and natural peat soil contained the highest number of Basidiomycota. The top species in natural peat swamp forest included Sugiyamaella paludigena, Polyancora globosa and Ganoderma gibbosum. The mineral soil enriched the abundance of Penicillium herquei, Sugiyamaella paludigena and the disturbed peat soil contained the highest frequency of Polyancora globosa, Gymnopilus lepidotus. According to the PCoA analysis, the community structure of fungus in natural peat soil differed significantly from mineral soil (P=0.04) and disturbed peat soil (P=0.039). No significant difference was found for bacterial species richness (Chao1) among the sites. The diversity of bacteria in disturbed peat soil significantly differed from the other sites (P<0.05 and P<0.05). eleven bacterial phyla and 53 genera were examined. All of the three sites contained the similar abundance of Proteobacteria. The natural peat swamp forest and disturbed peat soil harbored the most abundant Acidobactria. Genera Mycobacterium, Gp1, Gp13, Gp2, Burkholderia, Actinospica, Aciditerrimonas were found in all the sites. Genera Granulibacter, Gp4, Acidisoma, Clostridium_sensu, Clostridium_ XI were only observed in natural peat swamp forest. Genera Rudaea, Rhodopila, Streptomycetes were found only mineral soil. The PCoA analysis showed that the structure of bacteria in natural peat swamp forest significantly differed from the disturbed peat soil (P=0.045). Overall, the bacterial species richness and diversity are more among the sites than of the fungi. J. Biodivers. Conserv. Bioresour. Manag. 2019, 5(1): 133-144

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 align="center"><strong>Abstract</strong></p><p>Efforts of restoration of degraded tropical peat swamp forest were facing constraints due to the low available nutrient level of peat. The transplanted peat swamp forest species seedlings experienced low survival rate and poor growth performance. This study aimed to demonstrate the response of ten tropical peat swamp forest species seedlings whether climax and pioneer species to macro-nutrients addition in the nursery. The growth performance of climax and pioneer tropical peat swamp species seedlings was recorded following addition of macro nutrients of Nitrogen (N), Phosphorus(P), Potassium(K) and Dolomitic limestone (CaMg). The result showed that <em>Alstonia spatulata</em> and <em>Parartocarpus venenosus</em> showed positive growth response following macro nutrients addition. This study concluded that tropical peat swamp pioneer species has lower necessity for macro-nutrients addition than tropical peat swamp climax species.</p>
