Thorpe Meadows

June was a busy month, when we were creating new ponds down at Thorpe Meadows, in fields surrounding Peterborough Rowing Lake.  The seven newly created ponds will hopefully provide perfect breeding areas for amphibians and support a whole range of aquatic invertebrates. These areas are immediately adjacent to the new ponds constructed at Boardwalks Nature Reserve and will provide perfect opportunities for our native amphibian populations to expand. As the ground here was a combination of clay and river sediments we had to monitor the ponds to see if artificial liners would be needed.

In August, the decision to use liners for two of the newly created ponds at Thorpe Meadows was taken. The ground in this area contained a layer of gravel deposits which allowed drainage through the clay, so the ponds were not holding enough water to stay unlined.  With the help of some super keen volunteers we worked hard to line the ponds using bentomat geosynthetic clay liner and then covered them with spoil from the pond.  The clay in the liner will puddle and seal, retaining any water in the pond and so ensuring the water levels do not fluctuate too dramatically.

A massive thank you to everybody that came down and helped us, Chris and the Nene Park volunteers, BoJo, Richard, Ross, Gazz and Ben.  It was a fantastic team effort on a difficult surface with rain!
