Habitat & Geographic Range

Blauwal

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 11 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Taiwan), Europe (4 countries), and South America (Colombia, Ecuador). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Kleines Wintergrün

Habitat

Found across multiple habitat types including temperate broadleaf and mixed forests, temperate coniferous forests, and boreal forests and taiga, among 4 distinct biome types within the Palearctic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Found across Europe (7 countries) and North America (Canada, United States). Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Blauwal

The largest animal ever known to have lived on Earth, blue whales can reach 33 meters and 200 tonnes — their hearts alone weigh as much as a small car. Found in all oceans, they migrate between polar feeding grounds and tropical breeding areas. Filter feeders consuming up to 4 tonnes of krill daily. Endangered, with global populations estimated at 10,000–25,000 after near-extinction from 20th-century whaling.

Kleines Wintergrün

Pyrola minor, commonly known as the common wintergreen or lesser wintergreen, is a small evergreen perennial herb in the family Ericaceae, listed as Critically Endangered on the IUCN Red List, reflecting severe and ongoing population declines driven primarily by habitat loss, succession of open woodland habitats, and changes in land management practices across its native range. The species occurs in Europe and North America, typically growing in acidic, humus-rich soils in boreal and montane coniferous or mixed woodlands, heathland, and mossy habitats. Pyrola minor is characterized by its rosette of dark, glossy, rounded evergreen basal leaves and a leafless flowering scape bearing a dense raceme of small, nodding, pale pink to white bell-shaped flowers produced in summer. The species requires mycorrhizal associations with soil fungi for successful establishment and growth, making it highly sensitive to disturbances that disrupt fungal networks in the soil. Unlike most of its congeners, Pyrola minor has an unsegmented, short, straight style protruding from each flower, a key distinguishing character. Biological traits including average lifespan, rosette diameter, and mass remain poorly documented in standardized databases. Conservation of Pyrola minor typically requires careful habitat management to maintain suitable open woodland and heathland conditions, prevent encroachment by taller vegetation, and preserve the intact soil fungal communities upon which this increasingly rare species depends.
