Only a handful of lichens were actually known to occur at Wimpole until a recent survey undertaken by Mark Powell. THE LICHENS OF WIMPOLE HALL. He looked at the whole estate including the parish church. The habitats range from natural situations like the woodlands and trees, to some local rock strata, namely chalk, but he also looked at the built structures which, because of their varied geological components, were found to host a great variety including this Map lichen found on the roof of Wimpole Hall on the south facing slates. We will update this page with the species found shortly. In the meantime you can find out more information about lichens from the British Lichen Society.
