Physically remove problematic plants
A replicated, randomized, controlled study in 2003–2006 in a soak (fen-like part of a bog) in Ireland (Crushell et al. 2011) reported that plots cleared of floating vegetation developed low cover of open water plant communities (if completely isolated from the surrounding bog) or high cover of fen-characteristic species (if partially isolated). No statistical tests were carried out. Three years after vegetation removal, completely isolated plots had 35% vegetation cover, comprised entirely of aquatic herbs (bryophyte, cottongrass Eriophorum angustifolium and sedge Carex rostrata cover all 0%). In partially isolated plots, vegetation cover was 85% (including wetland herbs: 40%; all bryophytes: 70%; Sphagnum moss 11%; cottongrass: 3%; sedge: 4%). In control plots from which vegetation was not removed, vegetation cover was 100% (including wetland herbs: 50%; all bryophytes: 95%; Sphagnum moss: 13%; cottongrass 3%; sedge: 3%). In October 2003, six 4 x 4 m plots were established. Floating peat and vegetation were removed from four random plots, of which two were then partially isolated from the surrounding bog (with porous plastic membranes) and two completely isolated (with impermeable rubber membranes). Two plots were not manipulated. In July 2004–2006, cover of every plant species was estimated in each plot.
