Ivy and saplings should be removed from memorials and monuments. Crumbling stones should be left standing unless they prove to be positively dangerous. Not only do they testify most eloquently to the inevitable natural decay of most stone but, by their breakdown, they can provide the habitat or mineral release which will help to sustain some of the plants and animals characteristic of the particular soil condition or pH. Restrict cleaning to the absolute minimum and only use a soft brush and plain water. Before you start, it is advisable to link up with your local lichenologist and genealogist so that you can agree a course of action. Parishes should be encouraged to use local stone, if at all possible, for new memorials. A FINAL WORD Field work in churchyards or cemeteries can be a new experience for the orthodox geologist accustomed to wide-open spaces or quiet coasts where one rarely meets another person. By contrast, many people from a local community find time or cause to sl A into the churchyard or cemetery and they will nearly always have a curiosity as to what you are doing. This can lead to a fruitful Contact and provide yet another challenge to the commitment of how best to conserve our natural heritage in stone. Seek out your local Geological Society; the local museum or County or Urban Wildlife Trust may be able to help.
