Jon Mooallem, from the NYtimes, wrote a fascinating article about training wooping cranes to migrate through costumes and ultralight planes. He raises some pointagnt concepts about re-introduction, particularly on the increasing dependents of human interaction for a species survival and the extent we have become involved to protect “conservation-reliant species”.

” Having disrupted natural fire cycles, we’re forced to suppress fires in some areas and set them in others. We control predators, mop up pollution or clear out invasive species. We slip contraceptives to overpopulations of deer and the plague vaccine to ferrets; call in sharpshooters in helicopters to assassinate every last feral pig from certain islands; teach California condors not to perch on power lines; pick up migrating salamanders and carry them safely across a California road; and install feeders to satiate the Devil’s Hole pupfish, a species of small blue fish that lives exclusively in a particular pool of warm water in the Nevada desert. “If humans had the inclination to give up, this would be the one species given up on,” Kierán Suckling, executive director of the Center for Biological Diversity, says of the pupfish. “You could say it wouldn’t matter — it has very few ecological interactions with anything else in the world. But just the opposite has happened. I think we’ve got a very unshakable ethic to prevent extinction in this country.” – from Rescue Flight by jon mooallem, nytimes.com
