This project places autonomous SONAR bioacoustic recording units at three NEON sites along the Central Flyway to listen for the faint calls migrating birds make as they fly overhead at night, and uses those SONAR recordings to train a neural network that can identify the calls to species, which most existing bird-sound classifiers are not trained to do. Battelle, through the NRSS, is providing installation, power, network connectivity, routine maintenance, and end-of-project removal at NEON’s Lyndon B.

This project studies how temperate forest trees adjust their leaf physiology and traits in response to the combined stresses of climate change and forest fragmentation, using drone-collected, sunlit top-of-canopy leaves from red oak and red maple at the Climate Interactions with Forest Fragmentation (CLIFF) Experiment at Harvard Forest.
