The Bronze Frog, (a subspecies of the northern green frog) is becoming quite common in the Pacific Northwest, but on Vancouver Island, it is invasive and should be considered a serious threat to our indigenous frog species that live on there. This frog is a small to medium size frog that can reach up to 10 cm in length. The frog gets its name from the coloration of its skin, they are a bronze color. Read More….
These giant bullfrogs are showing up all over the Pacific Northwest, and they just may be spreading a deadly disease to other native frog species. The Bullfrog itself is unaffected by this disease.

Frogs are amphibians. Most frogs on Vancouver Island are born in water as tadpoles and gradually change into frogs, although some frogs, known as direct developers, are born as full frogs. This allows them to be born and live far away from water, such as on mountaintops. A frog mainly lives on insects and small animals like earthworms, minnows, and spiders. Frogs don’t need to drink the way we do, they simply absorb water through their permeable skin!
Vancouver Islands’ tiniest frogs are smaller than a penny, but did you know that the world’s largest frog can grow to be longer than 30 cm and weigh more than 3 kilos! There are more than 4,700 species of frogs around the world. There are about 90 species of frogs in North America. Unfortunately, around 120 amphibian species, including frogs, toads, and salamanders, have disappeared from the planet since the early 80s.
Frogs can be found on every continent in the world except Antarctica. However, the highest concentration of frogs is found in warmer tropical climes. On Vancouver Island, you can find bronze, bull, northern red-legged, chorus, and the western toad. Frogs are known as indicator species and can tell us how healthy an ecosystem is.
The majority of amphibians complete the first part of their life cycle in the water and then move onto land as adults. Vancouver Island supports two species of native frogs and the Western Toad. A further two species, the Bullfrog and Bronze Frogs, are introduced and now pose a serious threat to our native frogs.
