Our river Alyn here in North Wales has really suffered with the heat and very very low water, most of the fish seem to have vanished. Our river gets major floods 3 or 4 times a year scouring the bed each time. Many years age we had beds and beds of Ranunculus but theses have vanished. We have tried to reintroduce the weed with no success as it keep getting washed away or covered with silt! Many methods have been tried but failed, any ideas from other who facets simular problems would be greatly welcomed?
Simon.

Hi Simon
It may be a long shot but I wonder if swans are eating it all up? I have fished a stretch of the Wylye and it was totally denuded of ranunculus one year by a family of swans and all the fish vanished to where there was weed. It was thick in places but where the birds had taken up residence it was a virtual moonscape.
I have spoken to a riverkeeper friend of mine who suggests that it could be low flows that are the culprit and says that if you can create a pinch point of sorts to speed flows up that might help. It is likely that the roots are under the gravel but choosing not to grow. There are apparantly lots of theories on ranunculus growth or not as the case mey be.
On the river Frome that I fish, the high water levels earlier this year have resulted in masses of ranunculus!
Bad luck matey. Regards to you both, I was on the lower Wye yesterday and the water temperature was 72 degrees! Needless to say the salmon were not interested.
Cheers
Glyn

Hi Glyn.
No swans to blame this time!

Ranunculus is very sensitive to flow changes. On my local Driffield Beck the Ranunculus is so thick this year that you can virtually walk on it, whilst a few years ago there was virtually none. It likes high flows & suffers badly in low flow years.
