We are doing a garlic mustard removal in early May along the AT near here. With 14 miles of trail and no vehicle access along the stretch we will be doing I do not see taking out bags of garlic mustard as possible. Instead, we will be leaving easily monitored piles as far apart as possible.</div><div id="yui_3_16_0_1_1428689327328_5423" style="color: rgb(0, 0, 0); font-family: times new roman, new york, times, serif; font-size: 16px; background-color: rgb(255, 255, 255);" dir="ltr"> </div><div id="yui_3_16_0_1_1428689327328_5349" style="color: rgb(0, 0, 0); font-family: times new roman, new york, times, serif; font-size: 16px; background-color: rgb(255, 255, 255);" dir="ltr">Multiflora rose in our area is going extinct due to 2 diseases and a mite.

So we bag garlic mustard and most of the stiltgrass.</div><div id="yui_3_16_0_1_1428689327328_5517"><br clear="none"></div><div id="yui_3_16_0_1_1428689327328_5518">I do believe that none of the non native plant residue is beneficial to the native woods; we have masses of oak leaves and other native debris, so I just hope that piles of multiflora roses, burning bush, barberry, and honey suckle bush will decompose together with the native plant debris without causing too much harm or slowing down the growth. Our piles are 5ft tall and I lean on them to condense them.Since we have few volunteers we have left behind a lot of pulled out invasive material in the woods in piles.(They make very good bird and animal shelters.) I pay attention to not allow privet to touch the forest floor. We also compact the ground, disturbed by the digging and pulling, with our feet. I know that some people prefer to cut the stem and paint, but that is not the issue right now</div><div><br clear="none"></div><div>My aim is to leave as much natural area between the piles to give native vegetation the right environment, since we still have tons of small saplings and herbaceous plants growing and exploding when we remove the invasive plants.</div><div><b>Question: does it make a difference whether we make these concentrated piles or whether we just spread all the removed branches and roots of invasive bushes over the entire area.</b></div><div><br clear="none"></div><div><b>Question: will planting new saplings between cut multiflora roses without removing or killing the roots make sense? Will the competition of the cut roots not prevent growing of the newly planted saplings?</b></div><div><b><br clear="none"></b></div><div>Thank you very much for responding. </div><div>Pia van de Venne, Volunteer coordinator Murrysville Parks 724 733 2770</div></div></div><br clear="none">_______________________________________________<br clear="none">MAIPC mailing list<br clear="none"><a href="mailto:MAIPC@lists.maipc.org" target="_blank" rel="nofollow" shape="rect" ymailto="mailto:MAIPC@lists.maipc.org">MAIPC@lists.maipc.org</a><br clear="none"><a href="http://lists.maipc.org/listinfo.cgi/maipc-maipc.org" target="_blank" rel="nofollow" shape="rect">http://lists.maipc.org/listinfo.cgi/maipc-maipc.org</a><br clear="none"><br clear="none"><br clear="none"></div></div> </div> </div> </blockquote><div style="color: rgb(0, 0, 0); font-family: times new roman, new york, times, serif; font-size: 16px; background-color: rgb(255, 255, 255);"> </div></div></body></html>
