River Annan DSFB Fisheries Management Plan 2009 – 2014Control measures should aim to prevent flowering and if this is achieved beforeseeds are set, eradication is possible in two to three years. Again, glyphosate or2,4-D amine may be used. The best results are achieved while the plant isactively growing in early spring. Other recognised methods of control are cutting,pulling and grazing by livestock.The RADSFB has undertaken an extensive survey of both the above speciessupported by SEPA, Dumfries & Galloway Council and Solway Heritage.Examples of the extent of invasion of these species in the Annan catchment areshown in Figure 4.2.1. At present it would appear that the control of Himalayanbalsam would be far too extensive and costly to be attempted by the Board,however, a programme of control for Japanese knotweed may be possible withfinancial support.ActionDescriptionReactive orProactiveTimescale5.2.5.a5.2.5.b5.2.5.cContinue to monitor the presence of invasiveplant speciesDevelop strategy for control of invasive plantspecies.
