What do trees tweet?

iD magazine - - Questions & Answers -

More than 300 mil­lion peo­ple use the so­cial-net­work­ing ser­vice Twit­ter each day. Lately, this has even come to in­clude a few trees. As part of a study on the cli­mate in Ger­man forests some trees were out­fit­ted with mon­i­tor­ing de­vices and set up with Twit­ter ac­counts. They in­de­pen­dently tweet their vi­tal sta­tis­tics, such as evap­o­ra­tion and wa­ter flow, con­vey­ing mes­sages like “I am thirsty.” The trees’ equip­ment in­cludes sen­sors and mea­sur­ing in­stru­ments and even a WLAN con­nec­tion. In ad­di­tion to the first test trees in Ger­many, there are also tweet­ing trees in the Nether­lands and Bel­gium. They raise aware­ness of cli­mate change and its con­se­quences for trees.
