[MAIPC] Invasive plant removal (Pia van de Venne)

Wed Apr 15 07:27:50 PDT 2015

This thread gives me the chance to boost for one of the speakers at MAIPC's 2015 conference:

Sara Kuebbing from the Yale School of Forestry and Environmental Studies will be talking about the impacts of co-occurring invasive plants species, how multi-species invasions can differ from single-species invasions, and what that might imply for managing ecosystems with multiple invaders.

So, save the date for:
"Research Applied in Invasive Plant Management"
Tuesday, August 4 & Wednesday, August 5, 2015
Juniata College, Huntingdon, PA

The keynote speaker will be Johnny Randall, Director of Conservation Programs, North Carolina Botanical Garden.  He'll be talking about invasive seed dispersal by birds and other animals.  Other confirmed speakers include:

Art Grover, Penn State
Lea Johnson, University of Maryland
Jorge Bogantes Montero, Anacostia Watershed Society
Vanessa Beauchamp, Towson University
Samantha Schneider, Rutgers University
and
Benjamin Prater, Wild South

Registration and a full agenda will follow in late May, at this link<http://www.business-services.upenn.edu/arboretum/ed_conference_ipc.shtml> on the Morris Arboretum website.

Hi Pia, and thank you for all your work!  I would strongly recommend removing or killing multiflora roots, as I've found that those I cut tend to just put up new sprouts and come back thicker than ever.  I've also pulled up many roots that are vastly larger than the sprouts coming off them, which suggests they can survive repeated cutting/browsing over the years.  Removing the root balls or killing them through herbicide is the only way I know to ensure no regrowth.

I would also not recommend re-compacting the earth after disturbance except to refill obvious holes.  Intentional compaction beyond what the site already experiences through volunteer activity could suppress native regrowth.  Also, if there is any seedbank of Japanese stiltgrass in the soil, it will germinate aggressively once the soil is disturbed.  That's why I now advocate for killing multiflora roots with herbicide (cut & paint method) rather than pulling the roots out if there is any stiltgrass in the vicinity.

I think it's fine to scatter and/or pile cut invasives, except for those that will re-root or those that will put all their remaining energy into seed production, like garlic mustard.  If you are coming back to a gm site year after year, you can bag plants in black plastic and leave the bags, then pick them up the next year.  The heat will kill the seeds.

Hello,

During the 16 years that I have assisted in the removal of invasive plants, I learned that garlic mustard should be certainly taken out of the woods because of the amount of toxins in the plants. So we bag garlic mustard and most of the stiltgrass.

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

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.

*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.*

*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?*

Thank you very much for responding.

My feelings are that carrying out garlic mustard and?Japanese stilt grass from places like the Appalachian?Trail is?not feasible.? 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.?Multiflora rose in our area is going extinct due to 2 diseases and a mite.? The bush honeysuckles are having serious issues here.? Part of my summer research will be to monitor and try to transfer the diseases between plants.? I will be looking for mites as the vector and trying to transfer aphids between plants.?? I found that last fall when I tried to pull bush honeysuckles out they came without much effort.? We left the plants we pulled out in place with the roots exposed.?Ailanthus altissima in on the list.? I am going to try to see if I can find a volunt  eer friendly way to transfer the diseases between trees.??????????????????????????????????????????????????????????????????????????????????????????????
