What you see here, I think, is some sort of Pac-man-like game the trees are playing using the mycorrhizal network. Not as fast paced as what we play electronically, but then nature has its own timetable and pace. 😊
FYI: mycorrhizal (from Greek, Myco, “fungi” and Rhiza, “root”). The complex network connecting trees is dependent on a symbiotic relationship with microbes in the soil like fungi and bacteria. This symbiotic relationship between tree roots and fungi is known as the mycorrhizal network. —Science In The News, May 6, 2019 by Valentina Lagomarsino, Harvard.edu
