Summary
| Description |
English:
A lichen - Ramalina fastigiata This species was growing on a tree beside a footpath near Carman Reservoir.
Different lichen species vary greatly in their ability to tolerate air pollution (sulphur dioxide, in particular); this ability is quantified using the Hawksworth and Rose Zone scale, which runs from 0 ('most polluted') to 10 ('pure'). Ramalina fastigiata is assigned to zone 9, meaning that it is very sensitive to pollution; its presence here therefore indicates that air pollution levels in this part of the country are very low. For other Ramalina species, see: 933106 , 1073602 , 1073623 , 1843154 . |
