FLOATING PENNYWORT WORKING PARTY ON THE UPPER CAM, SATURDAY 1ST APRIL
2017
The invasive Floating Pennywort has in recent years colonised the lower
Bourn Brook, the River Cam and some of its minor tributaries, and is
affecting an SSSI near Wicken. It is also spreading down river on the
River Ouse and has been found as far down river as the Denver Sluice.
Since 1990, when it was first found in the wild on the River Chelmer in
Essex, it has spread rapidly and each year the number of affected sites
is expanding exponentially. In high season there are long stretches of
the Cam where dense mats reach out towards the centre of the river, and
in one part it has grown from bank to bank. It is a threat to
bio-diversity, a nuisance to river users and could increase the risk of
flooding.
This week contractors for the Cam Conservators have been removing as
much as they can from the upper Cam by mechanized means, but inevitably
this will leave floating remnants and inaccessible patches. If left,
these remnants will soon grow. The Cam Valley Forum and associates are
organising a major volunteer punt day on SATURDAY 1ST APRIL ON THE UPPER
CAM, and we are inviting you to join us. The target is to remove as much
as possible on the day, from Byron’s Pool to Scudamores boat station.
Scudamores are kindly giving us ten punts for the task, which will need
a minimum crew of one experienced poler, a raker and a netter. And just
as important, we also need people on the bank to rake out easy-to-reach
Pennywort and to help with lifting out filled bins from the punts and to
dispose of the material on the bank. Not everyone feels comfortable on
a punt in which case a bank job would be ideal. Up to forty people may
be required to take this project forward and we hope that you have the
enthusiasm and time to be part of this unique experience.
If you would like to take part, or have any queries please contact Mike
Foley (Cam Valley Forum) on mfpfoley@gmail.com
We envisage a early start time between 9 – 10 am and those punts that
go the furthest (Byron’s Pool) will not necessarily be out for longer
as there is much to do in the Grantchester Meadows area. It would be
very useful if you could supply details of your experience, how long you
want to be involved, and whether your role would be on land or on water.
An indication of whether you possess a long handled rake and are
prepared to bring it would also be useful.
More detailed information will be available to those who express an
interest.
