SO2 :: Lobaria species
Impact Type: Direct exposure to pollutant
Key Concerns:
Lobaria spp., as with other lichen species, are affected by SO2 (Hawksworth & Rose 1970a). Each species within the Lobarion may have a critical level at which point its population will begin to decline (Farmer et al. 1991a). See also Sulphur dioxide / Lichens(general)
Additional Comments:
Also sensitive to acid deposition.
