In Thunder Bay we share a prairie climate (sort of) but our green ash are thriving right now. I have noticed a few white ash that for the past 10 years at least have grown exceptionally well but this year have died back drastically.<div>
<br></div><div>If you look at the native range of green ash, it extends this far but not to the alberta Prairies. Likewise the white ash ranges not quite to here. I think Stephen is right on in thinking that this is the climate (sans global warming) keeping species distribution in check. </div>

<p class="MsoNormal"><span lang="EN-US" style="color:blue">We are seeing the same thing here in Red Deer. In late
September some Green Ash were still leafed out when the temperatures
plummeted. We observed many trees holding dead leaves over winter. To
compound the problem, we’ve received little precipitation in the fall and
little snow cover over the winter. This spring was hard on our trees
too. In April the temperatures were really mild until the end of the
month when the temperatures dipped going into the beginning of May. Many
Aspen poplar that were leafed out during this time period, suffered a bit of
frost damage. I would agree that it is abiotic.</span></p><div><div></div><div class="h5">

<p class="MsoNormal">In Saskatoon, many of our green ash are struggling this
year. We are seeing many trees with portions of the mid and upper crown
dying and often the lower crown is struggling to leaf out. In some cases
the trees have not leafed out at all. The damage is widespread throughout
the city. The trees are of mixed age but many are well established.
I’m wondering if other prairie cities are seeing green ash fail to leaf
out with significant dieback in the crown. </p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">We suspect the cause is abiotic. Not sure if this is
part of the story but we had very unusual Fall weather. We had an early
snow fall in October, exceptionally warm weather in November and then a very
sudden drop in December with no snow cover. We also had two weeks of warm
weather in January. </p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Any suggestions are appreciated.</p>
