Tweeting Trees
During the summer of 2017, the DendroLab led by Ute Sass-Klaassen at Wageningen University & Research, connected a poplar tree to a sap-flow sensor and dendrometer to measure the tree's sap flow and stem movement. This sensor data was directly tweeted out through the tree's Twitter account that subsequently gained over 4000 followers.
The image below shows a graph of the tree's sensor data where the day and night cycles of sap flow and growth can be observed.
