David, your posts are always interesting. I consulted Papa Google, and =

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 =
fragments.=20
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 =
woodlot.=20
=20
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!

Hi Dave P., Bev and all.
What an unfortunate name to be saddled with. Just this side of=20

Consequently, if something is threatened the best recovery remedy =
