Both sites are similar in so many ways. They are scientific experiments aimed at disentangling the biodiversity-ecosystem productivity relationship. Similar setup, similar age, and both are in the TreeDivNet, a global network of tree diversity experiments <http://www.treedivnet.ugent.be/>. Furthermore, both are very,very expensive to maintain. Hats off to Prof. Michael Scherer-Lorenzen and all the other researchers who devote themselves to this type of experiment. It is my privilege to visit both within one month’s window.
