Great Crested Newts
Great Crested Newts are the largest of our native newt species. They are widely distributed across Britain but have declined significantly over the last 100 years resulting in them becoming protected under European and UK law. The newts are active at night, spending the day at the bottom of ponds or in vegetation. They feed mainly on invertebrates and tadpoles.
Bats
Nine bat species have been recorded in and around the Graven Hill site including barbastelle bats which are considered to be one of the rarest bats in the UK. Numerous bat roosts have been located within the Graven Hill site, including within trees and buildings. Eleven active roosts were found in 2025, with further growth predicted in the coming years.
Badgers
Badgers are shy nocturnal animals that live in underground chambers connected to a network of tunnels known as a sett. Badger setts have been located within the Graven Hill site with at least three main setts being identified.
Reptiles
A small population of grass snake and common lizard has been identified within the Graven Hill site, utilising the network of ditches, semi-improved grassland, tall herb vegetation and woodland across the site to forage and rest.
