It’s the most detailed map of its kind so far. Animals like the black-footed ferret and California condor are represented, but so are groups often left out of such analyses: species of bees, butterflies, fish, mussels, crayfish and flowering plants. Not included are gray wolves, grizzly bears and other wildlife not at risk of global extinction.
Maps like these offer a valuable tool to officials and conservationists who are scrambling to protect biodiversity. That work is critical, because scientists say humans are speeding extinction at a disastrous pace.
