02Description

Species Profile

Species profile data sourced from the IUCN Red List of Threatened Species.

Storsporig päronlav faces severe threats from air pollution and climate change, which have dramatically reduced suitable habitat conditions across its range. The species' extreme sensitivity to atmospheric nitrogen deposition and sulfur compounds, combined with its slow growth rate and limited dispersal ability, has led to widespread population declines and local extinctions.

03Habitat

Habitat & Distribution

This lichen species occurs exclusively on the bark of mature deciduous trees, particularly pear trees and other Rosaceae species, in old-growth forests and traditional orchards with low pollution levels. It requires specific microclimate conditions with high humidity and minimal atmospheric contamination, typically found in undisturbed forest ecosystems.
