Dutch elm disease is caused by a fungus (Ophiostoma ulmi) that has been killing native elm trees in North disease is spread by both a native elm bark beetle (Hylurogopinus rufipes) and an introduced European bark beetle (scolytus multistriatus).Both native and introduced beetles create galleries through the bark of trees, allowing the fungus, (Ophiostoma ulmi) to colonize in these.

Dutch Elm Disease in Canada. According to reports, Dutch elm disease reached eastern Canada during the Second World War, and spread to Ontario in ; Manitoba in ; and Saskatchewan in In Toronto, 80% of the elm trees have been lost to Dutch elm disease; many more fell victim in Ottawa, Montreal and other cities during the s and.
Dutch elm disease, which has largely eradicated elm trees in North America, remains a problem on Dartmouth’s campus as well, threatening the trees that surround the Green, among others. However, with the help of the Beaty and a committed grounds-keeping staff, a rare amount of healthy elms remain a part of Dartmouth’s aesthetic image. The disease first appeared in northwest Europe in the early s, causing the death of European elms, and was given the name Dutch elm disease. In the s, the causal fungal pathogen (Ophiostoma ulmi) and the smaller European elm bark beetle were introduced to North America on imported logs.

The earliest external symptoms of infection are often yellowing and wilting (flagging) of leaves on individual branches (Figure 3).These leaves often turn brown and curl up as the branches die, and eventually the leaves may drop off.
