Expert Response

There are a number of different frogs native to Linn County, and in part, the frogs that you'll find on your property are a reflection of the habitat.

  • Great animals to have around and that aren't "picky" about habitat include American toads. They are very common and can thrive in more habitat types than any other anuran (amphibian) found in Iowa. If you want to make your property especially attractive to them, you can provide temporary breeding ponds (if these are not already present) and pieces of old terra cotta planting pots as sheltering spots for the toads. These provide areas that hold a little moisture because the sun isn't beating down on them and also provide shade and a slightly cooler temperature for the toad, as well as a place to hide from any predators. 
  • If you have roadside ditches that are not prone to rapid and high volume inputs of water from tiled fields, you're likely to have chorus frogs using the ditches for places to hang out and to breed (when there is some standing water present). These are the frogs of the prairie and are only about the size of the first joint of your thumb. By reducing/eliminating use of pesticides, you can encourage these populations. 
  • If you have a wooded area on your property or adjacent to it, you may very well have gray tree frogs (they'll start singing in May). 
Please contact me if you have further questions or concerns about Iowa's native anurans.
