lizard girl

When I received a photograph of the very pretty granddaughter of a friend I thought I'd try to capture her in a drawing. Of course my rendition does her actual looks almost no justice at all; in reality, her vivacity and confidence in the love that surrounds her defeats my small ability at portraiture. You may have noticed this little girl isn't standing in a doorway or a garden and neither is she accompanied by a typical household pet. Instead, she stands at ease with an iguana in equally sanguine posture. Do you wonder why?

Well, just a few days before I found her photograph in my inbox, I'd been reading about The Galapagos Islands, the remote archipelago where Darwin first conceived of his theory of natural selection after examining the unique fauna who lived there. Some 30 percent of the plants, 80 percent of the land birds and 97 percent of the reptiles are found nowhere else on Earth. Besides the famous giant tortoises, there were several varieties of oversize iguana - the land ones feed on cacti and shrubs while the marine iguana graze on seaweed near the shore.

Over the past 300 years, hunting and invasive species reduced both the giant tortoise populations and the lizards by an estimated 90 percent, destroying several species and pushing others to the brink of extinction, although a few populations on remote volcanoes remained abundant. Along with the pirates and eventual settlers, came goats, pigs, donkeys, dogs, cats, and rats. They trampled the delicate native plants, gobbled up turtle eggs, staged inexplicable attacks on land iguana colonies, snacked on baby chicks, and tore through cactus tree trunks. After the Galapagos National Park was established in 1959, park guards halted killing of tortoises for food, but those animals introduced to the islands continued to destroy the habitat and kill the native species.

 How researchers got rid of more than 200,000 goats is interesting (if somewhat gory):

In a project called Isabella helicopter aerial attacks eradicated 90 percent of the goats on that island. Although it's relatively easy to remove 90 percent of a goat population from an island as they become more rare, they are harder to find. Once they'd been educated and learned to hide, the hunters flying around in an expensive helicopter found no goats.

So they decided on a technique called Judas goats. Since goats are gregarious and like being in groups they captured individual animals, put radio collars on them and released them back into the wild where the goats would go and find more goats. A week or two later it was easy enough to find the hidden herds.

It's hard to write about the Galápagos without talking much about the tortoises, but since their story is far more famous than the efforts to protect the lizards, I just thought I'd let you know that overall the situation for all of the rare and beautiful species that Darwin described is far better now. Extraordinary measures that have been taken to protect these animals have been largely successful. At the same time the future remains mired in debates over how to protect the islands from the 150,000 tourists who visit each year, many of whom unintentionally bring invaders by depositing tiny seeds on trails, and occasionally fungi or insects that can cripple the fragile ecosystem. (Personally, I agree with Crow that tourists should stay at home, but that's a whole other subject.)

Land iguanas are large - more than 3 feet long - with males weighing up to 30 pounds. They live in the drier areas of the Islands, and in the mornings can be found sprawled beneath the hot equatorial sun. To escape the heat of the midday sun, they seek the shade of cacti, rocks, trees or other vegetation. At night they sleep in burrows dug in the ground, to conserve their body heat. They feed mainly on low-growing plants and shrubs, as well as fallen fruits and cactus pads. These succulent plants provide them with the moisture they require during long, dry periods. Land iguanas show a fascinating symbiotic interaction with Darwin’s finches, as do giant tortoises, raising themselves off the ground and allowing the little birds to remove ticks.

It's enough for me to know they're out there in hope that Earth will continue as the beautiful and diverse surrounding that gave us birth. My further hope is that little Lizard Girl and her friends will grow up to add to our knowledge and compassion for all God's creatures. We need more nature photographers and naturalists.

ps: My picture didn't do justice to the iguana either..
