Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Heim's Pottia faces significant pressure from urban development and infrastructure expansion across its limited Mediterranean range. The species' specialized habitat requirements make it particularly vulnerable to soil disturbance and changes in moisture regimes caused by construction activities. Climate change poses an additional threat through altered precipitation patterns that could disrupt the delicate water balance this moss requires for reproduction and survival.

Threat summary

Habitat

Heim's Pottia typically grows on calcareous soils and rocky substrates in Mediterranean coastal regions, often in areas with seasonal moisture availability. The species favors disturbed ground and open habitats where competition from other vegetation is limited, including roadside verges and abandoned agricultural areas.
