Report on the small terrestrial mammals of the Uut Murung Region, Central Kalimantan, Indonesia
Abstract
The known distribution of small mammals in Borneo largely reflects surveying effort, which is concentrated in the Malaysian states of Sabah and Sarawak as well as accessible low land Kalimantan. Here we present the findings of small mammal trapping surveys in two sites in a remote dipterocarp forest ecosystems in Murung Raya Regency, Central Kalimantan. To our knowledge, this is the first published account small mammal guild surveys in this region. Nine species of small mammals were found to be present over two study sites. The survey expands the confirmed distribution of the Grey Tree Rat (Lenothrix canus), constituting the second published record of the species in Central Kalimantan, and the first record of the species in northern Central Kalimantan. Also of note is the confirmed presence of the Chestnut-Bellied Spiny Rat (Maxomys ochraceiventer), a Data Deficient species thought to have a wide range yet captures are rare.
