elm leaves
Sadly, this may be the last year I am able to to gather leaves in the autumn from around the large elm trees on my property. The elm bark beetle with its load of deadly fungus (Dutch Elm Disease) has ravaged most of my beautiful elms over the past three years. I picked these up last weekend from around the base of my last really big living elm. I saw signs of the disease in this elm about a month ago. Goodbye elms.
There are elm cultivars that are DED resistant, planting them in the wild is impractical for me.

"Dutch Elm Disease was first identified in 1918 in Belgium by a Dutch pathologist who observed the fungus disease spreading through northern Europe. The disease likely arrived on logs from eastern Europe that were used to rebuild bridges. The disease as well as its carriers, the large and small European elm bark beetles, were inadvertently exported to North America on elm burls for the furniture industry. Three distinct entry points are known: Ohio in
1930, New Jersey in 1933 and Quebec around 1940. Despite efforts to halt it, the disease spread rapidly and virtually eliminated elm as an urban tree and reduced its status as a forest species in Ontario by the early 1970's."
