Schneider Electric has partnered with Automated Control Logic on a conservation project to restore Galapagos giant tortoise species to their natural habitat.
According to Schneider, Galapagos giant tortoises are massive herbivores that often reach more than 500 pounds. Before humans arrived on the Galapagos Islands, approximately 250,000 tortoises are thought to have lived there, but today, only an estimated 20,000 survive.The Galapagos National Park Directorate and Galapagos Conservancy started the Galapagos Tortoise Restoration Initiative to restore giant tortoise populations to their historical distribution and numbers. The project is supported by the Roosevelt Wild Life Station.
The gender of a tortoise is determined by the temperature of incubation, with females developing at slightly higher temperatures. In order to restore these species, tortoise experts and Galapagos National Park rangers can greatly speed up the process by collecting eggs from wild nests, and then bringing them into captivity for incubation and rearing until they are of a sufficient size to better survive in the wild at approximately five years old. By controlling the number of eggs incubated at the two temperatures, more female than male tortoises can be produced, which will eventually increase reproduction in the wild once these tortoises reach maturity.
Before enlisting the help of Automated Control Logic, the incubator heat delivery system used in the Galapagos National Park’s Tortoise Centers was a single hair dryer in each incubator, controlled by a thermostat. While successfully used for well over a decade, this is an imprecise way to control the temperature of the incubators, and so the heat delivery system made it difficult to assure the sex of the tortoise hatchlings. Equipment breakdowns could also cause unhealthy temperature fluctuations.
