Local groups tackling invasive species CAN help global biodiversity

We trout in the town types occasionally come in for some snide comments regarding playing round the edges of things at a local scale when we do volunteer balsam bashes and contract knotweed stem injection work. Well, as our own experiences with recovery of native seedbank plant species following the removal of Himalayan balsam concur, there is also now peer reviewed published science that indicates Global plant diversity can hinge on local battles against invasive species. It also explains why some of the previous literature can, sometimes, give conflicting conclusions depending upon the scale at which studies measured diversity.
