Northern Leopard Frog (Lithobates pipiens)
Place observed
Miller Marsh, Tylee Marsh, former golf course area.
Description
They have unique color patterns in shades of green and brown with rounded black spots on their backs and legs, but they can also be spotless. They have a white belly and two light colored dorsal ridges on their back. Males are generally smaller than females.
Habitat and feeding
The Northern Leopard Frog is found in southern Canada and the United States. In Rosemère, there is evidence that it has been observed in the Miller Marsh, Tylee Marsh and the southern wetland of the former golf course, which was once part of Tylee Marsh.
This frog usually lives near waterways (river, pond, wetland or lake) but can also be found in fields, as adults they spend more time on land than in water. It is carnivorous and active mostly at night.
Status
The Northern Leopard Frog is of special concern in Canada and is listed on the public registry of species at risk. Threats include habitat loss, invasive predators such as bullfrogs, domestic cats and some fish, pesticides and climate change. Their sensitivity to climate disruptions can compromise their winter survival and reproductive cycle.
Because of their highly permeable skin, frogs and other amphibians are very sensitive to changes in the state of their environment. The health of their population is a good indicator of water and air quality.
