Preparing for the arrival of a highly invasive beetle in Switzerland https://www.wsl.ch/de/projekte/preparing-for-the-arrival-of-a-highly-invasive-beetle-in-switzerland/
The emergence of visible tree-stress symptoms caused by the emerald ash borer occurs only several years after its arrival and are hard to tell apart from those caused by soil drought. Here, we investigate the potential of reflectance spectroscopy as an early-warning screening tool.
Consequently, the early detection and containment of these species have gained importance
