INFORMATION ABOUT BIOTOPE
Description of the area surrounding the biotope: Sabangau peat swamp forest, home to the world’s largest Orang Utan population and located to the immediate south and west of the city. Type locality is given as ‘Indonesia, Borneo, Kalimantan Tengah, about 3 km south-east of Palangkaraya in direction of Berengbengkel; 02° 16.5 S, 113° 56.6 E’.
Description of the underwater landscape of the biotope: In unaltered habitats the dense canopy of branches above means very little light penetrates the surface of such environments, and riparian vegetation also tends to grow thickly. The water is typically stained darkly with humic acids and other chemicals released by decaying organic materials
Description of the parameters of the habitat: The dissolved mineral content generally negligible and pH as low as 3.0 or 4.0. The temperature varies from 22°C to 28°C, and the hardness varies from 18 to 72 ppm
List of fishes and invertebrates occurring in the nature biotope: Betta，Parosphromenus，Rasbora，
List of plants found in the nature biotope: Cryptocoryne，Utricularia
Threats to the ecology: Most of the region’s forests have been cut down and burned, rivers polluted by domestic wastewater, and swamps filled in instead of rubber forests
