| Aquatic plant growth at Sharpsbridge |
Location
River Ouse at Sharpsbridge - TQ449207
Monitoring
The donor site on the River Ouse at
Sharpsbridge was inspected periodically to monitor the seasonal growth
of plants there and see if there were any adverse effects from removing
plants.
21st Aug 2000 - no adverse effects were apparent. One could not tell
that any plant material had been removed.
7th July 2001 - On 7th July 2001, a small work party attended the
site to remove some sheep netting that had become entangled in the
river bed. At the same time the donor site was inspected and it was
noted with some surprise that the whole of the Ranunculus bed had
been denuded by the winter spates and not a shred of vegetation remained.
Consideration was given to attempt a replanting of the site, but the
substrate and flow pattern had altered to such an extent that this
was not deemed feasible. The patch of Sparganium emersum upstream
of the bridge had not suffered any damage and appeared to be more
dense and extensive than before. |
