(typical rust plaques)This has not happened again in the following years. Unfortunately stilt grass has become too difficult in the 200 acre park because it has moved in so much from outside the park. But what was interesting today is the location of the original patch is now dominated by large fern patches, several times more than stilt grass, It is on the top and edge slopes of a mountain like area, which by the way has a wonderful large patch of Mountain Laurel about 150 feet from the fern and stilt grass area. This may be of interest for research on biological control of Japanese stilt grass. BTW, I am succeeding with all the other invasives, including garlic mustard, wineberry, beefsteak plant etc. Cheers</span><o:p></o:p></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Arial",sans-serif'> </span><o:p></o:p></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Arial",sans-serif'>Marc Imlay</span><o:p></o:p></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Arial",sans-serif'> </span><o:p></o:p></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Arial",sans-serif'>Natural Places Committee</span><o:p></o:p></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Arial",sans-serif'>Maryland Sierra Club</span><o:p></o:p></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Arial",sans-serif'>Board member MAIPC</span><o:p></o:p></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Arial",sans-serif'>301 442-5657</span><o:p></o:p></p><div id=DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2><p class=MsoNormal style='margin-bottom:12.0pt'><o:p> </o:p></p><div class=MsoNormal align=center style='text-align:center'><hr size=1 width="99%" noshade style='color:#909090' align=center></div><table class=MsoNormalTable border=0 cellspacing=0 cellpadding=0 style='border-collapse:collapse'><tr><td style='padding:0in 11.25pt 0in 6.0pt'><p class=MsoNormal><a href="https://gcc02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.avast.com%2Fantivirus&data=04%7C01%7Crod.simmons%40alexandriava.gov%7C8e3c983311bb4255402208d9770b9503%7Cfeaa9b3143754aeeadccc76ad32a890b%7C0%7C1%7C637671713901578306%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&sdata=McmeSUIbJBH%2B2MqtK6pqBwDL2GYKpbQsILLvD2YOQPo%3D&reserved=0"><span style='text-decoration:none'><img border=0 width=90 height=33 style='width:.9375in;height:.3437in' id="_x0000_i1028" src="https://static.avast.com/emails/avast-mail-stamp.png" alt="Avast logo"></span></a><o:p></o:p></p></td><td style='padding:.75pt .75pt .75pt .75pt'><p><span style='font-size:12.0pt;color:#3D4D5A'>This email has been checked for viruses by Avast antivirus software. <br><a href="https://gcc02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.avast.com%2Fantivirus&data=04%7C01%7Crod.simmons%40alexandriava.gov%7C8e3c983311bb4255402208d9770b9503%7Cfeaa9b3143754aeeadccc76ad32a890b%7C0%7C1%7C637671713901578306%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&sdata=McmeSUIbJBH%2B2MqtK6pqBwDL2GYKpbQsILLvD2YOQPo%3D&reserved=0">www.avast.com</a> <o:p></o:p></span></p></td></tr></table><p class=MsoNormal><br><br><o:p></o:p></p></div><div class=MsoNormal align=center style='text-align:center'><hr size=2 width="100%" align=center></div><p class=MsoNormal align=center style='text-align:center'><span style='font-size:12.0pt;font-family:"Cambria",serif;color:red'>DISCLAIMER: This message was sent from outside the City of Alexandria email system.<br>DO NOT CLICK any links or download attachments unless the contents are from a trusted source.</span><o:p></o:p></p><p class=MsoNormal>_______________________________________________<br>MAIPC mailing list<br><a href="mailto:MAIPC@lists.maipc.org">MAIPC@lists.maipc.org</a><br><a href="http://lists.maipc.org/listinfo.cgi/maipc-maipc.org">http://lists.maipc.org/listinfo.cgi/maipc-maipc.org</a><o:p></o:p></p></div></blockquote></div></div></body></html>
