Abstract:Birch invasion is a major problem facing managers of lowland heath in southern England, and herbicides are likely to play a major part in controlling this ‘weed’ species. One herbicide, Krenite, has been tested in two experiments and in larger scale case-study on lowland heaths, and its effect on birch, bracken, and the ground flora noted. In general Krenite produced a good kill of birch, and caused little damage to the underlying Calluna-dominated vegetation, and it appears a suitable herbicide for birch control in lowland heaths, but is less effective against bracken and willows.
