Found across Europe (6 countries). Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Bladder Moss

The common bladder moss (<em>Physcomitrium pyriforme</em>) is a small annual moss belonging to the family Funariaceae. It is classified as Least Concern on the IUCN Red List and is native to Europe and North America, with confirmed records from Luxembourg, Portugal, and the United States. <em>Physcomitrium pyriforme</em> typically colonizes disturbed, moist soils such as cultivated fields, riverbanks, and pond margins, where it forms low-growing green mats or cushions. The species is an ephemeral moss, completing its life cycle rapidly after disturbance events that expose bare soil. It is recognizable by its pear-shaped or inflated capsules borne on short setae, which give the species its common name. Spores are dispersed through the splitting of the capsule lid, and the plant often takes advantage of temporarily wet conditions for growth and reproduction. Biological traits of this species remain poorly documented in the scientific literature.

European pine marten

European pine marten (Martes martes) is classified as Critically Endangered (CR) on the IUCN Red List. Facing an extremely high risk of extinction in the wild due to severe population decline and habitat loss.
