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 ?

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.

(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".
