A North American toad is fighting its own battle with chytrid, a battle just as devastating as the one frogs in Panama are facing. The Wyoming toad (Anaxyrus baxteri) is one of the most endangered anurans (frog or toad) in North America. Historically, they were found in the Laramie Basin of southern Wyoming. Up until the mid 1970s, they were common throughout this region, but since then, the population drastically declined. Major threats are loss of habitat, pesticide usage and chytrid fungus. In 1994, the last wild toads were rescued from extinction when they were collected and sent to a captive breeding facility.
