People with fireplaces and wood burning stoves tend to keep a well
stocked wood pile year round. This was a harmless practice in the past.
With the invasion of Dutch Elm disease into Saskatchewan the situation
has changed. Provincial regulations now prohibit the use or storage of elm
wood. Elm firewood contributes to the persistance of Dutch Elm Disease
within an area. New infections will occur if diseased logs are transported
into a non-diseased region. Protect your elm- Do not store or transport Elm
Firewood.
There is alternate brown and beige layers
in the cross-section of the bark. This feature is
distinctive only to elms.
The surface bark is generally dark grey
to grey brown in colour. The outer bark is
composed of broad, intersecting ridges and
has a rough flaky appearance.
The Elm's Enemy
Dutch Elm Disease may be fatal to all elms in our area. Recognizing
the initial symptons is vital for disease control.
From June to mid July, watch for wilting leaves on one or more
branches in the Elm's crown. In a few days they turn brown and some
may fall off. From mid July to mid August, watch for yellowing of
premature leaf drop.
If you suspect that an Elm may have Dutch Elm Disease call the
City of Regina, 777-7000.
