In the late 1990s, an increase in the frequency of Flavoparmelia soredians was noted in the Netherlands, which, until then, occurred rarely in the country. This population increase followed a decrease in the levels of the pollutant sulphur dioxide. Punctelia borreri and Flavoparmelia caperata were two other foliose species that experienced a similar increase in regional frequency during this time.[2]
Taxonomy
    
The lichen was first formally described by Finnish lichenologist William Nylander in 1872 as Parmelia soredians.[3] Mason Hale transferred it to the genus Pseudoparmelia in 1974. It was later one of 17 species he transferred to Flavoparmelia in 1986.[4]
