Baited and unbaited glue-traps (Glor et al. 2000; Vargas 2000; Whiting 1998), funnel traps with and without floats (Casazza et al. 2000), drift fences in conjunction with pitfalls, round and square funnel traps (Christiansen and Vandewalle 2000), and habitat traps (Allan et al. 2000) have recently been proposed for the collection of reptiles and amphibians. Several collection techniques, such as collecting by hand, drum nets, fykenets, and funnel traps, have been successfully used for ecological and life history studies of aquatic or semi-aquatic snakes (Casazza et al. 2000; Fitch 1986; Shine 1986). In long-term ecological studies, funnel traps have proven to be an efficient method to systematically collect specimens, not only for aquatic species, but also for terrestrial and arboreal species (Casazza et al. 2000).
