Nesting boxes are to be placed in a Grade II listed park in Berkshire to encourage bats to roost and breed.
Herschel Park in Slough was landscaped in the 1840s as a private area for a Victorian housing development.
And a £2.7m project funded by the Heritage Lottery Fund is currently under way to restore the park to its former glory.
Volunteers are being invited to Wexham Nursery on Saturday to help make the bat boxes.
Tony Down, Herschel Park management officer, said: "Bats are an important part of nature and because so much of their habitat has been destroyed in the past they are now protected by law.
"Unfortunately the places where they like to roost are very vulnerable to disturbance as old rotting and hollow trees are often cut down and the eaves of houses are often treated with preservatives which can be harmful.
"By creating these special boxes, we hope to encourage bats to come and make their homes in Herschel Park and provide a safe environment for them to roost."
The bats the team want to attract include the long-eared bat and pipistrelle bats.
