According the hypotheses that plants can “communicate” among themselves, Olga Kisseleva is investigating the possibility of “eaves dropping” on this arboreal “dialogue,” and even taking part in it. This idea has given birth to the project in which trees can “communicate” on two levels: among themselves in the T2T (Tree – To – Tree) model, and on the level of the global T2N (Tree – To – Network). The trees included into the project can talk together across continents, and humans can follow them.
