Wood Frog (Rana sylvatica)

Wood Frog (Rana sylvatica)

Description:

• 3 - 5 cm, smaller in Ontario than in other parts of their range
• tan or brown with a distinctive black mask that extends across the face and behind the eardrums
• white stripe on the upper jaw

Habitat:

• very large range in North America, with a variable habitat
• moist woodlands near ponds that have emergent vegetation (for egg attachment)

Conservation concerns, distribution and status:

• common and widespread throughout Ontario, although some areas in southern Ontario no longer have populations probably because of the loss of forests and wetlands for agriculture
• acid deposition may not be effecting the wood frogs because they appear to be able to breed successfully in water with low pH levels
