I've worked with glossy buckthorn for several years now. Glossy buckthorn
that is merely cut down will absolutely regrow vigorously unless it is
re-cut over many years (similar to cutting down alder bushes-they spring
back up with astounding rapidity). They will absolutely not flop over and
perish. (If only!) This must be some other plant, or this site has been
contaminated with something.
The decision to used glyphosate very sparingly (taking care to apply it
directly on the plant and not using spray that may drift and hit non-target
native plants) is not one to be taken lightly. Those who have made the
decision to use it were oftentimes anti-spray/anti=chemical folks just like
me, who were forced to rethink a long-term strategy after extensive research
and consultation with experts about the ecological traits of this species.
After trying cutting, pulling, and girdling, I've revised my thinking to add
an additional 'tool to the toolbox'. (Obviously another 'tool' that must be
included is public education, and so the Herald article is a good start.)
Glyphosate is now used (though as sparingly as possible by painting foliage
and/or dabbing it directly on cut stumps) in several of our national parks
in eastern Canada and also by the Nature Conservancy. Glossy buckthorn is
rapidly closing in within Kejimkujik National Park, as well as along the
riparian zones of the Mersey and Medway rivers. It is rapidly appearing all
over the province. Some small woodlot owners who have carried out careful
selection harvests on their woodlot have received an invasion of glossy
buckthorn instead of valuable native tree species. (This is a serious
impact to their economic returns, and some are waiting for DNR to provide
some direction on this new and serious problem.) Since it has the ability
to grow in shade of undisturbed forests, as well as more open situations,
there is almost no where that it cannot establish. Sean Blaney at the
Conservation Data Centre informs me that it can take over and literally
transform fens. Fruit at cathartic to birds, and we are now left to
question whether it may even impact the ability for some avian species to
fatten up for migratory flights... (more research required). I don't mean
to be alarmist, but if we don't want to see great, impenetrable walls of
glossy buckthorns in protected areas and other biologically diverse areas,
then the initiatives that were otherwise criticised below must be adopted.
If you do not yet have glossy buckthorn on your land, I suggest you look
again (it is easily overlooked), or wait for its arrival. Coming soon to a
place near you! This is the "new normal".

I don't know the peculiarities of this invasive and hope I don't find out.
In any case, keep sharing those words of wisdom, David!

Dear All, June 9, 2014
I see some glysophate salesman has struck the mother lode. Using it to
control Glossy Buckthorn on 1,100 acres by pulling out seedlings and
painting glysophate on cut stumps of larger growth. At 1/2 acre per Sunday
it will take 2200 Sundays or 42 years. Meanwhile birds in fruit season can
sow 1,100 acres by noon. And if the soil has been disturbed by pulling up
seedlings then the take should be very good.

rath-of-volunteers-in-pugwash-estuary
And all this enthusiastic trampling will no doubt inflict damage on the
native plants that they intend to protect.
When one of these are cut they have to be hung upside down to prevent the
cut ends from rooting; according to this article.
They must be dealing with a very different strain of Glossy Buckthorn
than the one I know. A road that I cut through some dense Buckthorn
thickets, just after fruit maturity when they are most vulnerable, in 2002
has not regrown. If left alone they will eventually flop over and perish.
Yours truly, Dave Webster, Kentville
