Twenty-three infrared cameras were set: seven at an altitude of 200-300 m, eight at 100-200 m, and eight below 100 m, covering every region in Baiyun Mountain Scenic Area. Relative Abundance Index (RAI), trap occurrence, and time-period activity intensity index were used to compare and analyze the difference in activity rules, and a one-sample T-test was used for data conformed to a normal distribution. M. vaginalis was found to maintain a high activity frequency at mountaintop throughout the year but prefer to inhabit foothills during the dry season and hillside during the rainy season. The seasonal activity presented a vertical migration. The daily activity rhythm of M. vaginalis was bimodal, with peaks appearing at T 06-08 and T 17-19. Six flock types were recorded and male-female ratio was 1.17. Female with male and mixed flocks were considered as reproduction flock. The RAI of reproduction flocks showed no significant difference between dry and rainy seasons; the curves indicated that mating behavior occurred intensively in spring and autumn, and nurturing mainly occurred in autumn.

Abstrakt:As the only large mammal in Baiyun Mountain Scenic Area, Muntiacus vaginalis is a critical part of that forest ecosystem. Their activity rules and habitat adaptability are the basis of assessing the population status. As an effective method, infrared camera technology has been widely used in wildlife research. Placing infrared cameras for more than one year can help obtain the activity pattern of terrestrial birds and animals. Twenty-three infrared cameras were set: seven at an altitude of 200-300 m, eight at 100-200 m, and eight below 100 m, covering every region in Baiyun Mountain Scenic Area.
