The cemetery's grounds are full of trees, shrubbery, and wildflowers, most of which have been planted and grown without human influence.[citation needed] The grounds are a haven for birds and small animals, such as foxes. The cemetery is now owned and maintained by a charitable trust, the Friends of Highgate Cemetery Trust, which was set up in 1975 and acquired the freehold of both East and West sides by 1981. In 1984 it published Highgate Cemetery: Victorian Valhalla by John Gay.[2]
