[MAIPC] herbicide travel distance in Japanese honeysuckle runners??

[Nathan Hartshorne]

I'm never one to say don't control invasives, but it is worth pointing out
that deer often provide a lot of control of japanese honeysuckle,
especially when they are overpopulated, which is pretty common.  So
depending on the browse you see, you can even focus on other species.  One
big drawback of deer fences for restoration projects is that I would then
have to deal with a lot of honeysuckle climbing up the baby trees.
Obviously the control the deer provide isn't perfect, so it's good to do
your sprays anyways, but it's rare when we can enjoy deer doing something
so good, so I like to bring it up.
