<div dir="ltr">For what it's worth, I've been struck this year by how patches of fern resist stiltgrass invasion. For instance, a ten foot wide roadside with woods to the south and pavement to the north appeared to be 100% stiltgrass except for a small patch of sensitive fern, which looked to be free of stiltgrass altogether.<div><br></div><div><br></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Sep 13, 2021 at 7:09 PM Marc Imlay <<a href="mailto:ialm@erols.com" target="_blank">ialm@erols.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div lang="EN-US"><div><p class="MsoNormal"><span style="font-size:14pt;font-family:Arial,sans-serif">Today I was doing routine removal of non-native invasive species in my local park in Charles County Maryland, where a large patch of Japanese stilt grass died about a decade ago between flower and seed. (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<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:14pt;font-family:Arial,sans-serif"><u></u> <u></u></span></p><p class="MsoNormal"><span style="font-size:14pt;font-family:Arial,sans-serif">Marc Imlay<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:14pt;font-family:Arial,sans-serif"><u></u> <u></u></span></p><p class="MsoNormal"><span style="font-size:14pt;font-family:Arial,sans-serif">Natural Places Committee<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:14pt;font-family:Arial,sans-serif">Maryland Sierra Club<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:14pt;font-family:Arial,sans-serif">Board member MAIPC<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:14pt;font-family:Arial,sans-serif">301 442-5657<u></u><u></u></span></p></div><div id="m_4420002464416100972gmail-m_-1583574452101095829DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2">
