Ever since 2008 elms at the campus of the Göttinger Hochschule für angewandte Wissenschaften und Kunst (HAWK) are injected, This was commissioned by Prof. Dr. Rolf Kehr. Dutch Trig® is part of the training programme and the injections are done in the presence of a large group of students.
Also a large monumental tree at the cemetery of Hedemünden is injected. The injections were done in co-operation with Johannes Siebert, a student of HAWK who had chosen Dutch Trig® to be part of his graduation paper. Since 2010 the injections are done by Philipp Funck.
