As you can see, the waterfowl have already started building and in some cases they have started laying because of the mild winter. Those of us who monitored the situation last year will remember how nests were submerged due to semi-sunken pontoons, leading to the loss of both moorhen and swan eggs. See my post last year "Plight of nesting swans and coots in Greenland Dock" to see how bad things were for the nesting water birds. The situation is obviously unacceptable and we are waiting on Southwark Council to explain how they intend to respond to the situation.
Apparently, the Trust For Urban Ecology at Stave Hill Ecological Park used to be paid to upkeep, renew or maintain the pontoons, but after 2012 but that money was withdrawn, and Southwark Council has failed to act to ensure that the necessary work has been carried out by another party.
