This site is the largest elm woodland in the county. It was seriously affected by [[Dutch elm disease]], but many trees have regenerated from their bases, and the mixture of new growth and dead wood provides a very good habitat for insects and birds. There are the remains of a medieval manor and moat at the northern end, and a family of badgers have unearthed pottery dating back to the eleventh century.<ref name=WTBCN/> The ecological value of the site is enhanced by a stream, ponds, clearings and rides.<ref>{{cite web|url=http://www.sssi.naturalengland.org.uk/citation/citation_photo/1002107.pdf|title=Overhall Grove citation|series=Sites of Special Scientific Interest|publisher=Natural England|access-date=28 November 2016|archive-date=24 October 2012|archive-url=https://web.archive.org/web/20121024195312/http://www.sssi.naturalengland.org.uk/citation/citation_photo/1002107.pdf|url-status=dead}}</ref>
