This is a project I have been working on for over a year to photograph some of the animals that live inside a woodland at Frankley Water Treatment Works in Birmingham. The site is fenced off from the public and forms an isolated pocket of habitat in the city. The larger mammal's tend to hide away in the day when the site is busy with Severn Trent Water operations staff and contractors going about the daily jobs. After dark this changes and the animals come out.
