Conservationists can ensure the world’s rarest wild cat escapes extinction by doing one simple thing, say researchers — but they need to do it soon. What’s the secret? Start factoring in the effects of climate change when deciding how to save endangered species, says a new study. For the Iberian lynx, the most endangered wild feline of all, conservationists had better hurry. There are only 300 or so left in the wild. The Iberian lynx lives now only in two small areas of Spain’s Andalusian region. At one time it was plentiful throughout Spain, Portugal and southern France. Years of habitat loss, poaching and a diminished food supply have decimated its numbers. Should it become extinct, the Iberian lynx will be the first wild cat to do so in 2,000 years.
