Stockholm has had Dutch Dlm Disease since the end of the 1980’s and since then approximately 300 to 400 trees have been removed annually. Up until 2000 Dutch Elm Disease progressed slowly but in recent years has rapidly spread. In 2009 more infected trees than ever before were removed in the area of Stockholm. On the biggest churchyard (Norra Begravningsplats) alone 40 to 50 trees, over 20 meter tall and several hundred years old, were removed. As a result in 2010 the first round of injections was conducted.
