Breeding season for frogs

Question
Hello, I live in Southern california. Do frogs breed when the temperatures are warm? I know some websites say that breeding season starts in spring. I live near several creeks and ponds and at night I can't seem to hear or spot a frog anywhere. The temps have been in the high 60's and low 40's at night. Maybe it is too cold?

Answer
Hi Jimmie, Breeding is triggered by a combination of barometric pressure changes (which indicate impending rain), actual rain and temperature. Well I don't have first hand experience with Californian amphibians ( I live in the "other" Ontario, the Canadian one, lol) I would have thought that you would be hearing the breeding calls of the Pacific tree frog as they move to their breeding grounds. Breeding areas for this species can be virtually any body of water, large or small, temporary or permanent.  They are a very wide ranging species and reportedly the most abundant amphibian in your state. They tolerate cooler temperatures well but I have read that night time temps in the low 40'sF will cause them to cease calling and become inactive while it resumes in temps in the 45 - 50 F range.
Frog populations are in decline worldwide. It would be nice to think that it is just a little bit too cool for them just yet rather then think that your local ponds and creeks can no longer support their survival.
