More than a process that affects a few trees or a handful of isolated stands. As the image above demonstrates, snow-gum dieback is a large, landscape-scale process. In this image an entire hillside has succumbed to wood borers. Because of its scale, we need to apply techniques that draw together satellite-derived datasets and lab-based measurements of leaf reflectance. By doing so, we can separate out the reflectance properties of snow-gum leaves, and identify when they disappear as canopies die.
