Both tadpoles and adults require aquatic sites that do not completely freeze and that also maintain enough oxygen during the winter (Oldfield and Moriarty, 1994). In Maine, they remain under silt and dead vegetation during the winter (Hunter et al., 1999). Tadpoles probably remain active and grow during the winter in Louisiana but do not transform until warm weather (Dundee and Rossman, 1989). While overwintering, and despite cold temperatures, tadpoles remain active and likely feed (Getz, 1958). Green frog tadpoles will typically, but not always, overwinter for 1 yr prior to metamorphosing the following spring (Martof, 1952 Richmond, 1964 Vogt, 1981). They suggested that flowing water is used because it remains unfrozen and provides adequate oxygen. Lamoureux and Madison (1999) tracked 23 green frogs and found that they made extensive movements in late fall away from summer breeding ponds to areas of flowing water in streams and seeps. Green frogs probably do not migrate en masse to breeding sites. So much so that most species get enough O2 from absorption through specialized patches of skin. However, hibernating amphibians when hibernating have extremely low oxygen requirements. ![]() In summary, adults will hibernate in both water and on land, although underwater seems to be the most common site. The following is from Michael Lannoo (2005) Amphibian Declines: The Conservation Status of United States Species. ![]() Which answer is correct?Īnswer: Both of your answers could be correct. One specialist said they are trying to get to the woods to hibernate for winter and one shared that they can stay in the pond as long as it doesn’t freeze. We had to place a net five to six feet up to keep leaves and acorns out of the filtering system and now the frogs are jumping on the net. Question: My husband and I love to build wildlife habitat areas and have built a large pond with a strategic filtering system in the pond.
