Elusive tiger salamanders live in Edmonton-area wetlands — and environmental DNA proves it

Elusive tiger salamanders live in Edmonton-area wetlands — and environmental DNA proves it

Crime-fighting C.S.I.-type technology is being applied to wetlands in the Edmonton area, and turning up some surprising results. In September, scientists with the Alberta Biodiversity Monitoring Institute (ABMI) and InnoTech Alberta identified evidence of tiger salamanders in two wetlands. Sydney Toni, a knowledge translations specialist with ABMI, says scientists know that boreal chorus frogs, wood frogs and tiger salamanders have been visiting wetlands in the Edmonton area.
