Iguana Nest Boxes Recommended in Florida Keys

"Extensive use of artificial nest boxes by private property owners and land managers could potentially make a big dent in their population," Kenneth Krysko, Florida Museum of Natural History herpetologist said. The nest boxes are designed to humanely capture the troublesome lizards and their eggs, said Krysko, lead author of a study published in the September edition of Iguana: Conservation, Natural History and Husbandry of Reptiles. This is the first study to describe the natural history of the green iguana (Iguana iguana) and its expanding geographic range in south Florida. The lizards are native to central America down to Brazil and the Caribbean Islands.

"The historical background for the green iguana invasion of Florida is interesting and the description of the problem itself is valuable," said Gregory Watkins-Colwell, a senior museum assistant in the division of vertebrate zoology at the Yale Peabody Museum of Natural History. "I suspect it will not only be a valuable tool for controlling the invasive populations of iguanas in the Florida Keys, but also in other areas of Florida where high density of introduced fire ants may limit the available nest sites."

The study's authors recommend a simple nest-box design: a 6-inch diameter pipe about 2 feet long leading below ground to a 15-by-8-by-4-inch chamber and a lid permitting above-ground access and monitoring. The box can be constructed from plastic, rubber or fiberglass to be lightweight, moveable and reusable.
