The small mammals’ surveys were carried out in the Chu Mom Ray National Park during 2014-2015 by the Joint Vietnam-Russian Tropical Research and Technological Centre. This national park is located in Sa Thay and Ngoc Hoi districts of the Kon Tum province, close to the point where Vietnam, Cambodia and Laos meet. These preliminary studies focused mainly on taxonomical list composition and obtaining the data on biology of most abundant species of small non-volant mammals, which construct a background of fauna of the region. | HỘI NGHỊ KHOA HỌC TOÀN QUỐC VỀ SINH THÁI VÀ TÀI NGUYÊN SINH VẬT LẦN THỨ 6 STUDY OF SMALL NON-VOLANT MAMMALS IN CHU MOM RAY NATIONAL PARK (VIETNAM, KON TUM PROVINCE) ALEXEI V.

These preliminary studies focused mainly on taxonomical list composition and obtaining the data on biology of most abundant species of small non-volant mammals, which construct a background of fauna of the region. I. MATERIAL AND METHODS Field surveys were carried out during 1-12 May, 15-27 November 2014 and from 28 March to 13 April 2015 in eastern part of the National Park and its vicinity. Fieldworks were carried out in two localities 1) southward of Ro Koi Forest Station, 14°30'17" N, 107°43'22"E, elevation 680-750 m asl; 2) westward of Bar Goc Forest Station (“Botanical Garden”), 14°26'01"N, 107°43'14"E, elevation 710 m asl. The different biotopes at distances of 2-6 km from these forest stations were surveyed – secondary broadleaf forest, secondary forest with bamboo, forest along small streams, banks of river. Two types of trap were used. Large cage live-traps (25 × 11 × 11 cm) were set up, baited by a piece of foam rubber saturated with vegetable oil and pieces of apple, which was replaced every third day. Pitfall traps, ., plastic glasses 15 cm deep and 10 cm in diameter, were buried flush with the ground surface. All specimens were measured (standard external body .
