The reservoir of the invasive weed, Floating Pennywort in the ditch between Fen Ditton ditch and the Cam has been in our sights for about a year. It is particularly important because now that the upper river is clear of Floating Pennywort, Cambridge Conservators are undertaking a major pennywort clearance project in the main river downstream of Cambridge. This ditch is now the main upstream reservoir.
Dealing with it has been a joint effort, led by Mike Foley.
Part of the problem was that a fallen tree was blocking access from the river, but ownership was unclear. It was clearly going to take a while to resolve, so Cambridge City Council lent us a boom to help contain the pennywort in the ditch until we could sort out what to do….
It took many many months, but finally, thanks to persistant hard work by Mike, much pouring over maps and many discussions with the Parish Council, various potential land owners and their agents, Jesus College kindly agreed to “take responsibility” for dealing with the tree.
South Cambs District Council accelerated the permit for the treeworks as much as possible, but the nesting season had started before we got the OK to proceed. However, once Mike had done a Bird Survey to show that all was clear, Bidwells came in and removed the tree.The following day a team of 13 from Cambridge based technology company Sentec joined Mike to clear the pennywort.
If anyone who lives in the Fen Ditton area would like to help, do let us know.
