A wood frog. Photos by Denis Doucet, Fundy National Park. Wood Frogs are typically the first frogs to emerge here in New Brunswick each year. They can do this because of the "antifreeze" in their body (not actually antifreeze, but sugars) that enable them to freeze solid (!) and to resist temps down to -10C!
Spring Peeper. Photo by Denis Doucet, Fundy National Park Spring Peepers are our smallest frogs, only about the size of a loonie. Despite that, they emerge shortly after Wood Frogs, so they are remarkably resistant to cold temperatures too, despite being "cold-blooded." Peepers are named after their loud calls which can be heard reverberating around ponds and vernal pools in spring and early summer.
As part of Parks Canada’s ecological integrity monitoring program, we record the calls of these species with special equipment to register when they start singing in the spring. Changes in the number and seasonal timing of the calls will give us information which will help better assess ecosystem health in the park over time.
