Two new refuges for wildlife have been created at Hogsmill sewage works.
The new homes were installed as part of the development at the site, which has seen the construction of an odour control unit, and a combined heat and power (CHP) plant.
Hogsmill is rich in biodiversity, and is known to be home to grass snakes, slow worms and common lizards, and the new refuges have been constructed to allow them to hibernate over the winter period.
Rebecca Elliott, one of eight2O’s senior ecologists, said: “eight2O has a policy in which we aim to have no net loss for biodiversity on each project, with our ultimate aim to leave a site richer in biodiversity then when we started.
“We can do this in a variety of ways from planting native trees, creating wildflower bunds to undertaking voluntary conservation work in the local area.
“At Hogsmill, we achieved a positive status for biodiversity by keeping vegetation clearance on site to a minimum and creating two buried reptile hibernacula using recycled material.”
The hibernation pods were created by keeping vegetation clearance to a minimum, and creating the pods using recycled material and then burying them underground on the south-facing slopes
On another site, Bishop’s Green water works, six bat boxes were placed onto mature trees in sunny and sheltered spots after one tree was lopped.
