Thebreedingsite was completelyenclosed with two plastic sheets and funnel traps facing inwardsandoutwards weredistributedaround thefences. Notedirtroad adjacent to the breeding site. Close-up showing fence and funnel trap design (b). To hold the fence tightly to the rocky substrate, we weighted the base of the fence by folding over and stapling the lower edge of the plastic sheets and filling the resulting pocket with soil and small rocks. We inserted soil and rocks next to the funnel traps to seal spaces in the fence and placed soil on the floor of the funnel to facilitate toad entry.
