The Millersville University Conservation Biology Class is currently conducting a rapid biological assessment for the United States Fish & Wildlife Service at Wallops Island National Wildlife Refuge.  One of the field techniques we used was marking amphibians, mainly American and Fowler’s toads, with Visible Implant Elastomer (VIE) Tags.  Below is a video we made while in the field showing this marking process.  Marking these animals in the field will allow us to estimate their population size and density on the refuge.
