The Elm Bark Beetles, Hylurgopinus rufipes (Eichhoff), shows an attack as red sawdust appears on the bark of the elm tree indicating the presence of small round holes where the beetles enter. Another sign of Dutch Elm disease occurs in July, “Flagging” manifests as yellow, curling leaves and wilting foliage, and defoliation in the crown of the tree. These little insects may carry the Dutch elm disease from a diseased tree to a healthy one. “Staining “ will show evidence of red streaks through the sapwood in infected twigs. These little beetles can overwinter in the outer bark of the living elm, or survives as larvae inside the bark of a dead elm. “Dutch elm disease is a fungal disease that blocks trees’ water systems, killing them within one to two years.” Star Phoenix
Elm bark beetles are attracted to weak, and sickly trees. “Dying branches on an elm increase the chances that a beetle, possibly carrying the DED fungus, will make its way to your tree.” Fact Sheet # 3 Give your elm trees a healthy foundation with watering and retaining leaves for fertilizer at the base of the tree.
“The most effective management strategy for the elm bark beetle is to deprive it of its breeding habitat. This involves keeping elm trees healthy and removing dead and dying branches. It is necessary to dispose of any branches or wood from a fallen elm tree and either remove the stump or render it uninhabitable. Under no circumstances should elm wood be left lying around or stored for firewood or other purposes.” City of Saskatoon
“If someone brought in infected wood that had the beetle in the wood, that beetle would fly over top of a healthy tree and start to go into that healthy tree spreading the disease.” Michelle Chartier, Superintendent of Urban Forestry and Pest Management. CBC News
Tree banding is a preventative measure (so that the species which travels down the trunk of the tree to overwinter under the bark at the base of a live elm cannot make its downward journey. For this method to be effective, the band must be placed on the Elm tree by late September, and should stay on the tree until spring), similar to the practice applied for cankerworms.
An elm tree in Regina had to be removed last year due to DED and the city has had to remove 94 trees since the disease was first detected in 1981.”
“Saskatoon recorded its first case of DED in July 2015.“Global News
In the afforestation area, and across Saskatchewan, an Elm tree pruning ban is in effect between April 1 to August 31. The elm beetles are the most active during these months, and pruning the Elm tree during this time frame will increase the chance of infection. The newly created cut attracts the elm beetles.
Do not store, transport or use Elm Wood as in firewood or for other purposes. Report any Elm trees with signs of elm beetle distress to 306-975-2890. Only dispose of elm wood at the City of Saskatoon Landfill and never ever at a compost site.
“SOS Elms Coalition is concerned about the health of Saskatchewan’s community tree populations, in particular the threat of Dutch Elm Disease.”

“St. Barbe’s unique capacity to pass on his enthusiasm to others. . . Many foresters all over the world found their vocations as a result of hearing ‘The Man of the Trees’ speak. I certainly did, but his impact has been much wider than that. Through his global lecture tours, St. Barbe has made millions of people aware of the importance of trees and forests to our planet.” Allan Grainger
“The science of forestry arose from the recognition of a universal need. It embodies the spirit of service to mankind in attempting to provide a means of supplying forever a necessity of life and, in addition, ministering to man’s aesthetic tastes and recreational interests. Besides, the spiritual side of human nature needs the refreshing inspiration which comes from trees and woodlands. If a nation saves its trees, the trees will save the nation. And nations as well as tribes may be brought together in this great movement, based on the ideal of beautifying the world by the cultivation of one of God’s loveliest creatures – the tree.” ~ Richard St. Barbe Baker.
