[CANUFNET] green ash decline

[For Trees]

Yes, I do concur that the problem is widespread in Alberta from at least as
far north as Grand Prairie and through to the communities south of Calgary. 

 

Have observed lots of environmental damage (hail too, and other storm
injuries)to many different species of thin barked shrubs and trees as well
as the Green Ash, young Elms, Birches, and many newly planted trees
everywhere I've been this spring in Alberta. 

 

Almost makes you wish for more poplar, spruce and more native trees and
shrubs to be planted here on the prairies and foothills, eh?

 

Regards,

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.

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.  

 

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.  

 

Any suggestions are appreciated.

 

Thanks
