Monitoring Lichens on Monuments

摘要: Lichens grow naturally on all substrates, including very nutrient-poor ones. The reason for this is that they do not take their nutrients from the substrate, but mostly air and ambient water. Therefore can survive substrates. As are poor competitors tend to favour open habitats devoid of other vegetation. This especially true stony majority biodiversity rocks usually (except when permanently submerged or heavily shaded) consists lichen species. species (primarily) saxicolous in most parts world outside tropics. Even regions without natural rock outcrops, like Netherlands eastern England, [13]. Here, artificial such as brick, mortar, slate pebbles buildings, graveyards megalithic monuments.
