Native to Europe and North America, inhabiting ecosystems characteristic of the region.

Range

Found across Europe (6 countries) and North America (United States).

European hare

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical coniferous forests, among 7 distinct biome types within the Neotropic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Cliff Scalewort

Cliff Scalewort, Porella obtusata, is a leafy liverwort in the family Porellaceae found on cliff faces, shaded rock surfaces, and the bark of trees in moist, humid environments across Europe and North America. Porella is one of the most diverse and widely distributed leafy liverwort genera, with species adapted to a range of substrates from bark and rock to soil in forests and coastal habitats. Cliff Scalewort forms flat, overlapping mats of small, scale-like leaves arranged in two lateral rows and a row of smaller underleaves, creating a texture that gives the plant its common name. The green to brownish-green plants are tightly appressed to the surface, extracting moisture from rainfall and condensation. Liverworts in this family reproduce sexually when conditions are favorable, producing small capsules on delicate setae, as well as vegetatively through fragmentation. Porella species on cliff faces are sensitive to air pollution, particularly sulfur dioxide, and have declined in many industrial regions of Europe, recovering more recently as air quality has improved. They serve as indicators of habitat continuity and air quality in ecological assessments. Cliff Scalewort is not globally threatened but may be locally rare in heavily polluted or drought-prone areas.

European hare

European hare (Lepus europaeus) is classified as Near Threatened (NT) on the IUCN Red List. Close to qualifying as threatened, with populations that may become vulnerable without conservation action.
