Across the time series Palusophis bifossatus is the most frequently occurring speciesMethods
Pitfall traps were installed at three sampling points (field, field-forest transition, forest). In each area, ten 200-liter barrels (about 1.0 m in height by 0.6 m in diameter) were buried, spaced 15 m apart, connected by a 1 m high fence crossing the center of the barrels, totaling 160 m of fence at each point. The barrels remained open continuously for 18 months (540 days) and were inspected three times a week. Each inspection of a trap line lasted, on average, 20 minutes. Therefore, the effective time spent on inspection per trap-day was 0.857 person-hours per day (based on a 2-person-hour inspection work per trap every week), and the total work effort for inspection was 463 person-hours.Citation(s)
