Can common frogs survive in freezing temperatures?

They tolerate cold, but British common frogs do not have the freeze-tolerance of the North American wood frog and can be killed by freezing. Frogs overwintering underwater also need enough oxygen in the pond.

How long does it take for frogspawn to become a frog?

Metamorphosis often takes up to about sixteen weeks, but temperature, food and crowding can make it faster or slower. Some tadpoles do not complete development in the first season and overwinter in the water.

What's the highest altitude where frogs breed in Britain?

There is no 600-metre cut-off. Common frogs have been recorded breeding at 1,120 metres in the Cairngorms, and success at any high site depends on suitable water, temperature and the length of the season.

The Common Frog Altitude Question: When Amphibians Spawn Above 1,000 Metres

Common frogs breed in hill tarns and boggy pools above 1,000 metres, where tadpole development depends on temperature and some may overwinter. Adults tolerate cold, but cannot survive partial freezing.
