Abstract: The habitat selection of the sympatric species , giant panda and red panda , in the Qionglai Mountains was comparatively studied1 Among 48 parameters in 13 environmental factors studied , vegetation , food , water source , outer disturbance , and topography were the main factors influencing the habitat selection of both panda species. Both panda species tended to select habitats in the primary needle-leaf-broadleaf mixed forests or needle-leaf forests located in the middle or the higher part of the Qionglai Mountains with water source close by , relative less mammal and human disturbance , and finer bamboo growth. However , giant panda preferred to select habitats facing south or east with relatively gentle slopes , higher canopy , and less fallen logs and stumps while red pandas tended to choose habitats facing south or west with relatively deep slopes , lower canopy , and more fallen logs and stumps. The difference in habitat selection perhaps is one of the reasons for the long term co2existence of both panda species.
