Introduced iguana (Iguana iguana) populations in Lee County, Florida have increased to levels such that the county is now holding public meetings about the problem. Acording to this report from the Boca Beacon, public consensus is definitely that the iguanas must be removed. Unfortunately there are no easy answers here, especially as the Animal Services department maintains that their jurisdiction covers only domesticated animals, not exotic species like the iguana. Though there was this odd offer by a man who has apparently dealt with similar problems in Arizona and California.
