Tree Injury Update - Site Evaluation

White Pines showing symptoms
of herbicide injury
Tagged trees showing injury to
more then 40% of tree 
On Thursday the 22nd Dupont sent a team to evaluate the injury caused to trees from the herbicide Imprelis.  The team consisted of an arborist, and 2 representatives from a 3rd party.  Ryan Moore, and Fritz toured them around the grounds at Forest lake to all the trees expressing herbicide injury.  136 trees were evaluated, primarily White Pine, Norway Spruce and Colorado Spruce.  Of these trees, 81 of them showed signs of 40% or more injury. These trees have been flagged with an orange ribbon.  We have ordered tree tags to mark all 136 trees that were evaluated so we can closely monitor their health.  The report of all data collected has been sent to Dupont.  We will wait to be contacted, once Dupont has analyzed the tree data collected on site.
