Satellite images of Earth capture the imagination. They not only capture the beauty of the planet but also how humans are changing it. Conservation scientists have realized this, and the field of conservation remote sensing exploits the potential of satellite images for biodiversity conservation. Here, we expand this brief introduction to conservation remote sensing, and provide the rational for this book. By collating examples of where satellite remote sensing is being used in an operational way to inform conservation management, we aim to stimulate collaborations that will deliver projects that use satellite remote sensing in an operational way to inform conservation management.
