Latin name:
Bacidia incompta
Impact Type: Direct exposure to pollutant
Key Concerns:
Bacidia incompta severely affected by air pollution, as with so many lichen Spp. It is sensitive to SO2 (Biodiversity Steering Group 1995, Seaward & Hitch 1982).
Additional Comments:
There is no other literature available on this species.
Critical Load/level:
Habitat/ Ecosystem Type | Critical Load/ Level | Status | Reliability | Indication of exceedance | Reference |
---|---|---|---|---|---|
Forests and semi-natural vegetation |
20 µg SO2 m-3 annual mean and half-year(Oct-March) mean |
UNECE, 2004 | quite reliable i.e. the results of some studies are comparable |
Low temperature appears to enhance the negative effects of SO2, and the lower critical level of 15 µg SO2 m-3 is used where the effective temperature sum (ETS) (i.e. the sum of temperatures) above 5oC is below 1000 degree days (d.d) (Ashmore et al., 1994). |
