The roost tree characteristics of Indian flying fox (Pteropus medius) were studied in the midland lateritehillocks of northern Kerala in peninsular India. A total of 170 trees belonging to 20 families, 32 genera,and 37 species were identified as roost trees from eleven roost sites located in Kannur and Kasargoddistricts of northern Kerala. Roost tree parameters such as habit, origin, diameter at breast height (DBH),tree height, bole height, crown length, crown spread, and crown closure were analyzed. Families Ana cardiaceae and Lamiaceae represented more number of roost trees in the study area. The mean batabundance per tree for the entire study area was found to be 54.35 5.2 and it was highest for Ficusreligiosa (peepal) followed by Tetrameles nudiflora (false hemp tree) and Leucaena leucocephala (subabul). Bats showed a preference for native trees and did not show any difference in the selection of evergreenand deciduous trees for roosting. The study also revealed that P. medius prefers large trees with greaterheight, diameter, crown length, and crown spread. As the midland laterite hillocks are under severehabitat degradation, the study recommends preserving large trees for better conservation of theremaining habitats of P. medius in the area.
