[MAIPC] Honeysuckle Chipping

[Muth, Norris (MUTH)]

Alison,
I don’t have any direct experience managing Amur honeysuckle, but I might recommend going with whatever is most expedient. If moving the material is labor intensive I probably wouldn’t bother. Allelopathic studies are notoriously difficult to rigorously control properly and the table is tilted towards finding a negative impact (either because most things are at least a little bit allelopathic or because of larger issues with the experiments). It seems like the evidence for Amur honeysuckle allelopathy is pretty good (http://www.bioone.org/doi/full/10.3159/TORREY-D-15-00049.1) – but again – if it is labor intensive then I’m not sure I would bother.

Good luck!
Norris

Subject: [MAIPC] Honeysuckle Chipping

Hi everyone,
Does anyone have information about whether it is advisable to leave wood chips in place when removing amur honeysuckle from a forest?  I am planning to cut our dense infestation of honeysuckle at Woodend Nature Sanctuary and treat stumps with glyphosate.  We have a spicebush population that hopefully will benefit from the reduced competition, plus we will be doing restoration planting of tree seedlings, shrub and herbaceous species.  My concern is whether the allelopathic effects of amur honeysuckle arise only from root exudates of live plants or whether decaying honeysuckle woodchips would also suppress other vegetation.
Any advice would be much appreciated,
Alison
