David, your posts are always interesting.  I consulted Papa Google, and =
it seems the glossy buckthorn is damned by a great many =
people=E2=80=94Nature Conservancy, Tree Canada, et al.  Could it be that =
this plant is damaging to the ecosystem in climates like Ontario, but =
not such a problem in Nova Scotia?  Your comments have helped me =
appreciate the complexity of ecology.  It=E2=80=99s worse than middle =

Hi Nick & All,

    Glossy Buckthorn IMHO  is a positive for thinned woodland; thinned =
by windfall, tree death or cutting. Provided seeds are present it =
becomes established and grows rapidly and thus captures many mobile =
nutrients which might otherwise be lost. It discourages the gross =
overstocking by Ash which otherwise become a thicket of runts. =
Buckthorn, unless held up by other shrubs typically grow lanky, flop =
over and die. The odd one survives the floppy stage and generates a =
nurse canopy for real trees which typically take longer to get =
established. My once Buckthorn thickets are now largely Buckthorn =

    By arrangement I would be delighted to walk anyone interested =
through some of the patches which remain. It spreads rapidly because =
[gasp] birds mob these shrubs in season. But it does not "invade" small =
openings in the canopy so is absent or very sparse in most of my =


    Frankly I think the notion that it is undesirable is founded upon =
prejudice and nothing else.

Calm...i lived in southeast Kentucky

We had kudzu vine  that swallowed abandoned houses...crossex roads via =
phone lines

Scary but before we call Jesus and Mary we notice it did not enter =
intact woodland and was restricted to about 30m from the roaside.

We do have a couple of plants that are 9f concern because they do get =
into fairly intact ecosystems. I'd put glossy buckthorn at the top of =
the list and then in terms of potential for harm given reports from =
elsewhere, I'd be concerned about the spread of garlic mustard.


Glossy? It's naturalized now and is part of swamps and early forest =
succession. It's not the end of the world...its green it's a laxative =
for birds and it fits into a red maple alder tudspuck sedge swamp with =
no apparent diversity or community function effects.


Fight clearcutting and our inability to get any marine protected areas =
for the eastern shore because we don't want any impingement on rockweed =
harvest or oil and gas development.


Great name!
