Abstract. Simangunsong BCH, Manurung EGT, Elias, Hutagaol MP, Tarigan J, Prabawa SB. 2020. Tangible economic value of non-timber forest products from peat swamp forest in Kampar, Indonesia. Biodiversitas 21: 5954-5960. Development of alternative economy based on non-timber forest products usage is an important means to prevent forest conversion and preserve the quality of a forest ecosystem. The main objectives of this study were to identify and calculate the economic value from tangible/marketable perspective of the non-timber forest products (NTFPs) provided by peat swamp forest in Kampar, Sumatra, Indonesia. This is one of the largest remaining peat swamp forest ecosystems in the country. Seven villages located around that forest ecosystem with total forest cover area of 201,224 ha were chosen as samples. A conversion return approach was used to estimate the economic value of non-timber forest products. The results showed 18 kinds of non-timber forest products were identified, but only seven were used commercially by community. They are jungle rubber (Hevea brasiliensis), sago (Metroxylon sp.), swiftlet nest (Aerodramus fuciphagus), honey, betel nut (Areca catechu L), Agathis resin (Agathis dammara), and pandan (Pandanus amaryllifolius Roxb.) The obtained economic value of NTFPs was very low, which was about Rp 9,367.4 (or US$0.68 ha-1 yr-1). Market development of non-timber forest products is then crucial, and the government should play an important role in promoting it in collaboration with private companies. Non-marketed non-timber forest products and various environmental services should also be taken into account to measure that peat swamp forest ecosystem value. Otherwise, concerns about the sustainability of that forest ecosystem in Indonesia due to undervaluation of forest resources will continue.

The tropical peat swamp forest in Malaysia has reduced significantly due to increasing pressure for development and demand for agricultural land. Pekan peat swamp forest is part of the 200,000 hectares of peat swamp forest located in Pahang, Peninsular Malaysia. While more extensive studies were done on flora and fauna, the study on microbial diversity in this habitat is very limited. The highly acidic environment, low concentrations of nutrients and anoxic condition of the peat are among challenges that hampered the cultivation of microorganism from this environment. In this study two types of agar-based medium, M1 minimal medium (M1) and peat water medium (PW) supplemented with glucose, methanol and lignin were used to isolate bacteria from the peat sediment. In comparison to M1, the use of PW has resulted with higher number of isolates with different morphologies. The PW mainly contains the acidic peat water that was collected from the sampling location. Based on the growth on medium supplemented with lignin, selected isolates were identified using 16s rDNA sequencing. At least three of the isolates showed sequence similarity to Burkholderia sp., which is one of the common species, studied on their ligninase-producing abilities. The results from this study serve as the preliminary data for further work on growth characteristics and enzymatic potential of isolates from acidic peat swamp soil.

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.
