In late-June, Delaware's forests get an annual "physical" or "check-up" – just after spring's "leaf-out" blankets the state in a wave of green color. Just as people should visit the doctor to be screened for potential diseases, trees are examined with a variety of tools to hopefully spot minor issues before they turn into major ones. Armed with a digital camera, GPS technology, and a tablet equipped with specialized software and satellite data, forest health specialist Bill Seybold boards a small plane for a sky-high view of the First State. The annual aerial survey is specifically designed to detect potential threats that can only be seen from the air. Fortunately, early results from the 2018 aerial forest survey indicate no major outbreaks of tree diseases or insect pests.
