Lethbridge: The City is asking residents to refrain from pruning their Elm Trees, as of April 1st.

into place to prevent the spread of Dutch Elm Disease. Pruning Elm trees at this
time exposes wounds, providing an opening for Elm Bark Beetles, a carrier of the
"If your own tree doesn't leaf out this spring. What we tend to look for is,
once trees are in full leaf, usually mid-June through July, we'll see a branch or a portion of the tree that
will all of a sudden wilt, the leaves will usually curl up, turn brown and just
remain on the tree. Also, trees infected later in the season, might
change color and drop prematurely." said Urban Forestry Technician, Lindsay Bell. He said these are indicators a tree could be infected.
There has only ever been one tree in Alberta infected with Dutch Elm Disease. Provincial Regulations prohibit the storage, sale, or transport of elm wood.
"Don't move fire wood. That's the big thing. That's the reason we're telling
people don't bring firewood into the city. If you're out camping if you're in
another province or in another state, these beetles could come in on fire wood
and start affecting trees in our city." said Bell.
