Saving ‘El Escorpión.’ The critically-endangered Guatemalan Beaded Lizard. US correspondent Vickie Lillo gets up close and personal with the rarest of lizards, and examines conservation strategies to bring it back from the brink. he forked pink tongue flicks in and out of the venomous lizard’s mouth like a piston on a locomotive. In and out, in and out. Odour particles are thus conveyed to sensory cells above the roof of the mouth. “He’s tasting the air,” declares Ben Roberts, Deputy Director of Chehaw National Park in Albany (Georgia). “By doing this he can determine that there is food nearby.” T The biologist handles the Guatemalan Beaded Lizard (Heloderma horridum charlesbogerti), or GBL for short, with care. It is one of the rarest lizards in the world, and has been accorded critically-endangered status by CITES. Hailing from the eastern Motagua Valley of Guatemala, deep in Central America, this good-sized lagarto inhabits a 47,000-acre (19,020-ha.), semi-arid range of woodland and subtropical thorn scrub, approximating the size of a large cattle ranch in Texas. The cloud forests of the colossal Sierra de las Minas mountains form the northern boundary of the valley, shielding the remaining landscape from the moisture-laden currents of humid air blowing in from the Gulf of Mexico. Those winds deliver all their precipitation onto the steep slopes, creating, on the leeward side, a rain shadow in the isolated terrain below. An inhospitable community riddled with acacia trees, leguminous shrubs, and low-growing Opuntia (Prickly Pear) cacti. Unfortunately, the Guatemalan Beaded Lizard has to share this unique biome – a World Wildlife Fund-recognized ecosystem under threat – with impoverished subsistence farmers desperately trying just to eke out a living.
