Presentation Title

Using Novel Methods to Assess Instream Movement of Migrating Western Toads

Format of Presentation

15-minute lecture to be presented the Saturday of the conference

Abstract

Western toads are a species of conservation concern in BC; they participate in numerous ecological processes, act as an indicator species for ecosystem health and are in decline throughout much of their range. Understanding western toad movement is an important component of toad ecology and conservation; a historically overlooked element of toad migration has been instream movement. I studied the instream movements of a regionally and provincially significant population of western toads at Summit Lake, BC. I established used Fyke nets within streams to capture toads; this is a novel methodology for toad capture that has thus far only been employed in two studies, both of which occurred in Montana. I successfully captured toads in all non-larval life stages. A notable finding was the capture of a considerable number of toadlets involuntarily moving downstream during attempted migration to upland habitat. The high success rate in capturing toads and toadlets using Fyke nets suggests that there are many potential conservation applications for this methodology.
