Hi Nick & All,
Glossy Buckthorn IMHO is a positive for thinned woodland; thinned=20
by windfall, tree death or cutting. Provided seeds are present it=20
becomes established and grows rapidly and thus captures many mobile=20
nutrients which might otherwise be lost. It discourages the gross=20
overstocking by Ash which otherwise become a thicket of runts.=20
Buckthorn, unless held up by other shrubs typically grow lanky, flop=20
over and die. The odd one survives the floppy stage and generates a=20
nurse canopy for real trees which typically take longer to get=20
established. My once Buckthorn thickets are now largely Buckthorn=20
fragments.
By arrangement I would be delighted to walk anyone interested=20
through some of the patches which remain. It spreads rapidly because=20
[gasp] birds mob these shrubs in season. But it does not "invade" small=20
openings in the canopy so is absent or very sparse in most of my=20
woodlot.
Frankly I think the notion that it is undesirable is founded upon=20
prejudice and nothing else.
Yt, DW, Kentville
