GREENBELT, Md., Aug. 7 (UPI) -- NASA says satellites can help track zebras migrating in the African nation of Botswana, one of the world's longest migrations of the striped creatures.
Predicting when and where zebras will move has not been possible until now, researchers said, but with rain and vegetation data from satellites they can track when and where arid lands begin to green, and for the first time anticipate if zebras will make the trek, the space agency reported Wednesday.
