There have been unofficial releases of green, leopard and bull frogs into High Park’s ponds and wetlands in recent years, but their populations have not persisted.
The American toad, a terrestrial species that is more adaptable to urban conditions, breeds in the park’s wetlands and has recently become common. Their loud mating chorus can be heard in the spring.
Green frog has also recently become common.
