IRCF REPTILES & AMPHIBIANS • 21(2):83–85 • JUN 2014 T he Veiled Chameleon (Chamaeleo calyptratus) is an arbo- real lizard native to Saudi Arabia and Yemen, where it is found on high plateaus to elevations of 2,800 m and in foothills, forests, low-elevation maize fields, and inland river valleys (Fritz and Schütte 1987, Meerman and Boomsma 1987, Zari 1993, Showler 1995, Schmidt 2001). This spe- cies has been introduced via the pet trade to Hawaii (Kraus and Duvall 2004) and Florida (Krysko and Enge 2004), USA. In Florida, it has been established since at least 2002 (Krysko and Enge 2004) and evidence of additional indepen- dent introductions exist from Alachua, Collier, Hendry, Lee, and Miami-Dade counties (Krysko et al. 2011, Gillette and Krysko 2012). Herein, we document another introduction of C. calyptratus in Broward County, Florida. On 30 December 2013, the University of Florida received an anonymous tip about a possible population of Chamaeleo calyptratus on state-owned lands in Broward County. On 1 January 2014 between 1900–2100 h, JRE and MRR con- ducted a nighttime search around a Florida Highway Patrol station and area right-of-way. At approximately 1930 h, we observed an adult female C. calyptratus (photographic voucher UF-Herpetology 172296) sleeping on a Brazilian Pepper Tree (Schinus terebinthifolius) about 2.5 m above the ground (26.11969°N, -80.33859°W, Datum WGS84, 5 m eleva- tion). At approximately 2000 h, we observed flashlights in a nearby area. Upon contact, two people revealed themselves to be commercial chameleon collectors who had two C. calyptra- tus in their possession. The collectors told us the chameleons were collected from the same site that evening. At 2025 h, we observed an adult male C. calyptratus (UF-Herpetology 172297) sleeping on a S. terebinthifolius about 3 m above the ground (26.12038°N, -80.33814°W). Digital images of the chameleons were sent to Laurence L. Connor (Florida Fish and Wildlife Conservation Commission) who confirmed our identifications. Vouchered specimens are crucial in docu- menting introductions (Krysko et al. 2011) and these known vouchers represent the first two C. calyptratus from Broward County. On 2 January 2014, MRR and Michelle J. Curtis (University of Florida) conducted a second survey of the area. A C. calyptratus of unknown sex was observed at 2106 h, perched on a S. terebinthifolius about 3 m above the ground (26.11993°N, -80.33974°W). Another C. calyptratus of unknown sex was observed perched in another S. terebinthi- folius about 4 m above the ground at 2110 h (26.11972°N, -80.33869°W). Both chameleons were behind a fence, pre- venting collection or satisfactory photographs. The release of nonnative wildlife is illegal (Rule 68-5 F.A.C) and Florida law considers release of nonnative wildlife to be a misdemeanor (Florida Statute § 379.231). Despite this, multiple chameleon populations have been discovered throughout the state (Figs. 1 & 2), but primarily in south- ern Florida. Rumors abound that animals were intention- ally released by individuals interested in harvesting them from the wild for future sale in the pet trade. On several occasions, JRE and MRR observed collectors trespassing on posted private lands to obtain chameleons. For example, Oustalet’s Chameleons (Furcifer oustaleti) in Miami-Dade County, Florida, were first observed to be introduced into a private property (Gillette et al. 2010) and subsequently have INTRODUCED SPECIES IRCF REPTILES & AMPHIBIANS CONSERVATION AND NATURAL HISTORY WWW.IRCF.ORG/REPTILESANDAMPHIBIANSJOURNAL New County Record for the Veiled Chameleon ( Chamaeleo calyptratus Duméril and Bibron 1851), in Broward County, Florida, With Notes on Intentional Introductions of Chameleons in Southern Florida Jake R.
