Oregon Field Guide is your destination for outdoor recreation, ecology, natural resource and travel stories from across Oregon and the Pacific Northwest.
Video description: In 1993, two Pacific northwest researchers sounded the alarm about global amphibian declines. Twenty years later Oregon Field Guide tracked down the same researchers, Andrew Blaustein and Marc Hayes, to see what they've learned. Frogs and toads are still in decline and the causes are complex, including U-V radiation, water mold, chytrid fungus, aggressive bullfrogs and habitat destruction.
