Legality & restrictions on exporting
(THIS INFO WAS CURRENT AS OF 10/17/2000)
It is illegal to transport Jackson's from the Hawaiian Islands to the continental US without a permit from the (Hawaii) Department of Land & Natural Resources (DLNR). Doing so is a (class C) felony with a fine of $50,000 to $200,000. Also, it is a petty misdemeanor to transport Jackson's from island to island, and if caught this could result in a fine of up to $5,000. The DLNR will give a one-time permit (there are no fees involved) for up to four (4) animals per household for personal use. Permits are also given for an indefinite number of Jackson's for valid scientific research or educational purposes. There are no restrictions on the age, size or sex of the animals you take. These permits are only issued from the DLNR's main office in Honolulu, regardless of where the chameleons are purchased or collected. The requestor of the permit must be physically in the state of Hawaii, and can be obtained by calling or visiting the DLNR office at:
Department of Land and Natural Resources (DLNR)
Division of Forestry and Wildlife (DOFW)
1151 Punchbowl St., Rm. 325
Honolulu, HI 96813
(808) 587-0166
Contact person: Nancy Lisignioli
Again, do not request a permit until you are actually in the state of Hawaii. Although the office is in Honolulu, if you are on another island you can still request a permit and it will be faxed to you. According to the DLNR, scores of people have done/are doing this. However the airline you are traveling may have restrictions - some will not allow reptiles on board in the cabin or as luggage, so you may have to ship them as cargo. Make sure you check with the individual airline first.
UPDATE 2/7/01: You may have noticed lately that many stores are advertising Jackson's for sale from Hawaii, and they state that they were obtained legally. I recently read a post from a store stating that they obtained a shipment of Jackson's from "someone that was given a permit to remove the Jackson's from their property". Although this may have been said by the seller this is still illegal.
