Statement of Purpose
The International Iguana Society, Inc. is a not-for-profit corporation dedicated to preserving the biological diversity of
iguanas. We believe that the best way to protect iguanas and other native plants and animals is to preserve natural
habitats and to encourage development of sustainable economies compatible with the maintenance of biodiversity.
To this end, we will: (1) engage in active conservation, initiating, assisting, and funding conservation efforts in
cooperation with U.S. and international governmental and private agencies; (2) promote educational efforts related
to the preservation of biodiversity; (3) build connections between individuals and the academic, zoo, and conserva-
tion communities, providing conduits for education and for involving the general public in efforts to preserve
endangered species; and (4) encourage the dissemination and exchange of information on the ecology, population
biology, behavior, captive husbandry, taxonomy, and evolution of iguanas.

Editors’ Remarks
This is a special issue of IGUANA. One reason is that it is half again as long as a regular issue. We owe this to a
generous donation by Henry and Gloria Jarecki, who subsidized the extra pages in order to accommodate the
feature on Stout Iguanas (p. 39). They already have made tremendous contributions to the species’ chances for
survival by providing it with a second home on Guana.

This issue also includes for the first time several new regular features created in response to discussions by the Board
of Directors during the IIS Conference on Utila (p. 27). Each issue from now on will include at least one article
focusing on some aspect of iguana husbandry. The first of these, on Green Iguana communication (p. 50), was
excerpted from the excellent book by Gunther Köhler, which, unfortunately for most U.S. iguana enthusiasts, is
currently available only in German. In addition, each issue will profile an individual who has made significant
contributions to our understanding of iguanas. The inaugural profile (p. 53) features Fred Burton, the man behind
the Blue Iguana Recovery Programme. Also appearing for the first time is an historical perspective. These features 
will appear from time to time in order to lend some insights into the changing perceptions of iguanas over the years.
This issue’s perspective (p. 56) addresses Black Iguanas (Ctenosaura), which is particularly appropriate in light of the
ctenosaurs of Utila that so delighted the Conference participants.

We also provide a Species Profile (p. 36) that presents a suite of species instead of only one. We do not necessarily
intend for this to become the normal mode for these features, but decided that it was appropriate, at least this one
time, because of the unusual reptilian diversity on Utila and because it emphasizes how iguana conservation can
benefit an entire biotic community.
