Salamanders are iconic and influential members of northern forest communities. As one of the most abundant vertebrates in eastern North American forests, salamanders are considered “keystone species” because of their disproportionate roles as predators and prey in regulating food webs, nutrient cycling, and contributing to ecosystem resilience-resistance.
In addition to fulfilling key ecological functions, amphibians are our modern-day “canaries in the coal mine,” serving as a measure of environmental health.

Today’s post comes from Laura Sagermann, a Natural Heritage Education leader from Bon Echo Provincial Park.
Across Ontario, our provincial parks protect a wide range of diverse ecosystems and habitats from human impact, urban development and other environmental threats.
However, this protected land is not immune to invasive species. These are non-native species that have been introduced (either purposely or accidentally) and have negative effects on a region.
At Bon Echo, the latest invasive species to be found is the insect-fungus combination responsible for beech bark disease. Continue reading Downed trees become habitat for eastern red-backed salamanders
The next time you take your kids or grandkids for a trek through your favourite Ontario provincial park, stay on the lookout for salamanders. Some of these wondrous little amphibians are on the endangered species list so if you see one skulking through your park, snap a selfie and send it to Ontario Nature, or download a free app at ontarionature.org/atlas. Your scientific discovery could help scientists understand more about why these fascinating creatures are disappearing.
According to a study done by the International Union for Conservation of Nature, amphibians such as salamanders, frogs and toads are experiencing one of the biggest declines globally. In fact, 41 percent of amphibians worldwide are endangered or threatened, including here in Ontario.
