RE: [NatureNS] Glossy BuckthornHi Donna & All,
I am talking about Rhamnus frangula AKA, Frangula alnus & Glossy =
Buckthorn.
Cutting most woody perennials, including Glossy Buckthorn, off at =
the wrong time is quite ineffective as you say.=20
But for cutting to have maximum effect they should be cut off at =
the right time; just after current photosynthates have been spent =
growing shoots, roots and fruit but before downward flow into roots for =
storage commences. For most woody plants here August is safe.
And they do flop over when stands become dense especially if there =
are full scale trees nearby. They expend too much energy keep leaves in =
sunlight and not enough in stem diameter. If by chance a bunch become =
bent over by snow or ice it is game over. =20
This plant was brought over by the Acadians probably as a source of =
good porous charcoal for gunpowder. Do you not find it curious that it =
has become a 'pest' only in recent decades ? Why did it just sit around =
hatching evil plans for nearly 400 years ?
Yt, Dave Webster, Kentville

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=3Dchemical 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. =20
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".

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.

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.
