Sampling comments: "for leaf litter and top soil collecting thirty 1 × 1 m quadrats were set up along each linear transect placed alternately on its left and right sides 10 m away from the line. Within each quadrat, the leaf litter and soil samples at 1 - 2 cm depth were collected. The soil was sieved through a 2-mm sifter for leaf litter sifting. Additionally, ten unbaited pitfall traps were placed 10 m away from each other and left for 24 hours"
