My colleagues and I recently installed a large network of tree sap sensors, point dendrometers, and meteorlogical station to study the Lycorma delicatula (Spotted Lanternfly) threat to timber species. An automated system conisting of 16 sap flux sensors and 32 point dendrometers were installed on eight Black Walnut trees. A meteorlogy station including an anemometer, precipitation bucket, radiation sensor, soil moisture sensor, air temperature and relative humidity were installed.
