Substantial growths of aquatic macrophytes are known to occur in the lower reaches of
the R. Wye during the summer months and in 1975 the distribution of major plant species
was assessed and the biomass of representative plant stands estimated in one 30 km
stretch. This very modest programme has now been complemented by a more
comprehensive study of macrophytes of the R. Wye by UWIST, under contract to Nature
Conservancy Council (UWIST 1976g)
