Decades ago, a trove of Cold War spy satellite images was declassified, offering unique glimpses into the past in key sites around the world.
Scientists have tapped into these images from a wide range of disciplines, including archeologists and civil engineers. Their use in conservation and ecology have been limited, researchers say, but it may be time for that to change.
In a recent paper published in BioScience, researchers considered how these spy images could be used to study changes in ecosystems, species populations and land use since the 1960s. A 2020 study by the same scientists looked at how these images revealed unexpected declines in bobak marmots (Marmota bobak) in Eurasia.
