Norway maple is one of the most common trees on Main Street, and has over all but the last few years been an essentially "no fail" healthy tree. However, this seems to have changed. Now, many have dieback of large branches, and some trees are dead. I'm assuming this is because the last few years have been unusually wet (?). If there's some other cause though, that could be very important with respect to this species ability to outcompete native (and other exotic) tree species.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Chris<o:p></o:p></p></div></div><p class=MsoNormal><o:p> </o:p></p><div><div><p class=MsoNormal>On Sun, Aug 25, 2019 at 1:31 PM Marc Imlay <<a href="mailto:ialm@erols.com">ialm@erols.com</a>> wrote:<o:p></o:p></p></div><blockquote style='border:none;border-left:solid #CCCCCC 1.0pt;padding:0in 0in 0in 6.0pt;margin-left:4.8pt;margin-right:0in'><div><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><b><span style='font-size:14.0pt'>Hi Chris Spaur,</span></b><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><b><span style='font-size:14.0pt'> </span></b><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><b><span style='font-size:14.0pt'>Thanks for your report of a finding of massive death of mature Norway Maple over many acres that were healthy just 2 years ago at Mt Airie in Virginia up the hill. </span></b><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><b><span style='font-size:14.0pt'> </span></b><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><b><span style='font-size:14.0pt'>Marc</span></b><o:p></o:p></p><div><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><b>From:</b> Marc Imlay [<a href="mailto:ialm@erols.com" target="_blank">mailto:ialm@erols.com</a>] <br><b>Sent:</b> Wednesday, August 7, 2019 10:08 AM<br><b>To:</b> 'Ossi, Damien (DDOE)' <<a href="mailto:damien.ossi@dc.gov" target="_blank">damien.ossi@dc.gov</a>>; <a href="mailto:Katplantsnow@gmail.com" target="_blank">Katplantsnow@gmail.com</a>; 'katplants' <<a href="mailto:ncw@gmail.com" target="_blank">ncw@gmail.com</a>>; Foster, Donna M -FS <<a href="mailto:donna.m.foster@usda.gov" target="_blank">donna.m.foster@usda.gov</a>>; <a href="mailto:morlousky@appalachiantrail.org" target="_blank">morlousky@appalachiantrail.org</a><br><b>Cc:</b> Tancos, Matthew - ARS <<a href="mailto:matthew.tancos@usda.gov" target="_blank">matthew.tancos@usda.gov</a>><br><b>Subject:</b> Juniata follow up Surveying for native biological controls<o:p></o:p></p></div></div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'> <o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-size:14.0pt;font-family:"Helvetica",sans-serif;color:red'>Hi Kathy, Donna, Damien, and Marian,</span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-size:14.0pt;font-family:"Helvetica",sans-serif;color:red'> </span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-size:14.0pt;font-family:"Helvetica",sans-serif;color:red'>Thanks for helping prepare a message to be sent out by our MAIPC board to many IPC groups, Master gardeners, etc. promoting surveys for observations of major impacts on invasive species such as Damien found at Heritage Island on Japanese Honeysuckle. </span><span style='font-size:14.0pt;font-family:"Arial",sans-serif;color:red'>We can report a major devastation of any invasive species to Matt Tankos of ARS for research into native biological control as is happening now with Japanese Honeysuckle.
