<p class="MsoNormal"><span style="font-size:14.0pt;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<o:p></o:p></span></p>
