bullfrogs

As a member of frogwatch I have read with great concern the destructive power of bullfrogs to other native frogs and also other species. I have not heard of any bullfrogs in my pond or in this area. I have notice some very large tadpols in my pond that have not turned into frogs and or toads and this is the beginning of the trird year. If these are bullfrogs I wish to remove them before they can do any damage to other native species. I have notice they are feeding off of other frog eggs which have been recently laid. My question is whether I should remove them and could there be more beneficial frogs/toads that would take up to 3 yrs to develop? I am trying to stop a problem before it starts. Controlling the Bullfrogs! I would also like to know if there are any books in print that would help in identifying tadpols. My pond is located in Western Maryland.

The American Bullfrog is a problem only where it isn't native, mostly the western US. It is native to your area and should not be considered a pest to be controlled there. Sure, it eats things, but that's its job. It's been doing it for millions of years, with no ill effects. It's not good policy to try to control native predators; people have been doing that for a long time, usually with disastrous results. We can't go around deciding which native species we like and which we don't. They're ALL essential.

Tadpole identification is difficult and often requires killing the tadpole. A key to common eastern species is at http://www.trentu.ca/biology/berrill/IdentificationTable.htm
