I think frogs deal well with cold, better than
fish, at any rate. You might consider keeping
an airhole open in the ice, assuming you are
where your pond ices over. You might also
provide cover (plants, like ornamental grasses)
near the pond so they can move in and out with
some chance of avoiding predators.


It will freeze over during the winter but I could put a small heater in
it to keep it open and there is plenty of plant life on both sides of
the pond. Is it possible that they could winter there?
