Churchyards, metal mining sites, gardens, monuments & urban habitats can all be valuable for lichens.
Throughout Britain and Ireland churchyards offer a wonderful resource of lichens - and so need conserving carefully.
Gardens containing older structures and trees are more likely to contain notable lichen species.
A lichen mosaic is a valuable and aesthetically pleasing natural feature of ancient monuments.
Mines and mine-spoil can support a specialised community of metalliferous lichens.
