Luckily, it doesn’t compete as well in forested or mesic sites. However, on more xeric sites (rocky roadsides, ROW’s, barrens, cliffs) it can certainly be more aggressive and take space and resources away from native plants that might use those habitats. Additionally, we’ve monitored it increasing on many of the Marcellus pads and ROW’s, and it has been a management concern on some areas we are maintaining as grassland for rare bird species.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Verdana","sans-serif";color:#17365D'><o:p> </o:p></span></b></p><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Verdana","sans-serif";color:#17365D'>Andrew Rohrbaugh</span></b><span style='font-size:10.0pt;font-family:"Verdana","sans-serif";color:#0B3468'> | Botanist<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Verdana","sans-serif";color:#0B3468'>Pennsylvania Department of Conservation & Natural Resources<br>Bureau of Forestry | Ecological Services Section<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Verdana","sans-serif";color:#0B3468'>PO Box 8552, 400 Market St, Harrisburg, PA 17105-8552<br></span><span style='font-size:10.0pt;font-family:"Verdana","sans-serif";color:#66AC2D'>Phone:</span><span style='font-size:10.0pt;font-family:"Verdana","sans-serif";color:#0B3468'> 717.705.2823 | </span><span style='font-size:10.0pt;font-family:"Verdana","sans-serif";color:#66AC2D'>Fax:</span><span style='font-size:10.0pt;font-family:"Verdana","sans-serif";color:#0B3468'> 717.772.0271<br>anrohrbaug@pa.gov<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Verdana","sans-serif";color:#0B3468'><a href="http://www.dcnr.state.pa.us/"><span style='color:#123B79'>www.dcnr.state.pa.us</span></a><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> MAIPC [mailto:maipc-bounces@lists.maipc.org] <b>On Behalf Of </b>Stephen Hiltner<br><b>Sent:</b> Wednesday, July 01, 2015 12:59 PM<br><b>To:</b> Bailey, Whitney - FS<br><b>Cc:</b> maipc@lists.maipc.org<br><b>Subject:</b> Re: [MAIPC] spotted knapweed in the east<o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal>It was invasive in prairie restorations in Ann Arbor, MI.
