<p class=MsoNormal><span lang=EN-CA>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.  <o:p></o:p></span></p>

<p class=MsoNormal><span lang=EN-CA><o:p> </o:p></span></p>

<p class=MsoNormal><span lang=EN-CA>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.  <o:p></o:p></span></p>

<p class=MsoNormal><span lang=EN-CA><o:p> </o:p></span></p>
