Natkon is official sponsor of the new WSL demo site at Birmensdorf (Switzerland). The site is used to introduce visitors and scientists to the methods used in the long-term monitoring projects of WSL (LWF and TreeNet). Natkon supports the site currently with two dendrometers of the type ZN12-T-2IP. One beech and one spruce trees are i.a. equipped with a dendrometer detecting stem radius changes over bark and on the xylem in parallel.
