We also have had, since 1985, some of the <i> Rhamnus frangula, </i> or <i> Frangula alnifolia, </i> the Shining or Alder-leaved Buckthorn, but on our dry oldfields it's much less aggressive (and the bunnies don't much favour it). In nearby Limerick Forest, however, the whole style of logging has had to be changed because the Shining Buckthorn comes in so densely and rapidly under any new opening in the canopy.fred schuelerhttp://doingnaturalhistory.comnoreply@blogger.com
