Sampling comments: "Sampling was carried out during August 2005... using three sampling methods: plot sampling... visual encounter surveys... and pitfall traps with drift fences... For plot sampling, we set 30 quadrats of 5 x 5m on the forest floor, totaling 750 m2 of forest floor sampled... For the visual encounter surveys... searchers walked along random transects... totaling 75 hours of sampling effort... We also established three pitfall trap systems that consisted of ten 30-liter buckets buried in the ground, each set at ca. 5 m apart from the next, with soft plastic drift fences about 50 cm high extended between them... Pitfalls remained open for a total of 16 days"
