IUCN: population narrative

This is a competitive perennial species (Dierssen 2001) growing mostly on rotting stumps and humic slopes, in shaded and humid conditions (Casas et al. 2009). The species is paroicous; in Great Britain capsules are abundant, mostly during spring and early summer; gemmae are occasional (Blockeel et al. 2014). Presently, the overall population size is large and the current population trend is thought to be stable.

IUCN: habitat narrative

This liverwort occurs in acidophyte-subneutrophyte substrata (Dierssen 2001), most frequently on rotting wood, on tree boles and trunks, occasionally on base-poor rocks, sometimes on soil in shade (Blockeel et al. 2014). In Britain and Ireland the altitudinal range goes from sea level up to 450 m Asl (Blockeel et al. 2014), but in the Iberian Peninsula may be found from lowlands to high mountains (Casas et al. 2009) and in the Azores it was found from 10 m to 875 m Asl, mainly in native forests (Gabriel et al. 2011).

IUCN: threats narrative

Even though this species may be locally threatened (e.g., in Italy), at the European level there are no major threats to this widespread species.

IUCN: conservation narrative

This species is known to occur in protected areas and no research or conservation action are currently needed. It has been assessed as Near Threatened in Italy (Hodgetts 2015).

IUCN: rationale

European regional assessment: Least Concern (LC) EU 28 regional assessment: Least Concern (LC) Lophocolea heterophylla is a circumpolar temperate liverwort species, occurring in Europe from mid Scandinavia southwards, less frequent in the Mediterranean region, and also in Macaronesia and central and eastern Europe. This species is assessed as Least Concern in Europe since it has a large geographic range, the population size is rather large and the current population trend is assumed to be stable. At the European level there are no known major threats.
