<DIV><FONT size=2 face=Arial>The Regional Forest Network in Eastern Ontario has
been having ash decline in our region for a number of years. .The Ontario
Ministry of Natural Resources is pointing to stress in the trees most likely
from a few hot dry summers we had a few years back. The complication we have is
the Emerald Ash Borer in Ottawa, thus the Candian Food Inspection agency is
going to start doing some assessment of these areas which has ash
decline.No EAB has been found outside of urban Ottawa.</FONT></DIV>
<DIV><FONT size=2 face=Arial> In Carleton Place where I live
and am the resident arborist we have taken down some affected ash but
found no signs of EAB . These trees were hit hard in the ice storm of 1998, have
been attcked by vagabond aphids and have gone through those droughty periods.We
are ruling it to these stresses but realy do not know the exact cause of this
decline in Eastern Ontario, West Quebec.We are still looking at the situation we
have.</FONT></DIV>

<DIV><BR></DIV>We had significant leaf drop from white ash and some Manitoba
maples this spring in Port Credit (South Mississauga, Ontario). I've
been watching them for signs of the Emerald Ash Borer, but that doesn't seem
to be the cause. Perhaps it is related to the very dry spring
here???<BR><BR>

<P class=MsoNormal><SPAN style="COLOR: rgb(31,73,125)">Hi Jeff it sounds
like we had a similar fall to yours. Indian Summer followed by a sharp
freeze and trees held their leaves all winter. We however are not seeing any
significant dieback in ash (that isn’t related to the western ash bark
beetle anyway). Good luck</SPAN></P>

<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. </SPAN></P>
<P class=MsoNormal><SPAN lang=EN-CA></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.
