Habitat & Geographic Range

Quendelseide

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, montane grasslands and shrublands, and Mediterranean forests and woodlands, among 8 distinct biome types spanning the Afrotropic and Neotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (South Africa), Europe (9 countries), North America (Canada, United States), Oceania and the Pacific (Australia), and South America (Argentina, Venezuela). Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Graureiher

Habitat

Typically found in diverse ecosystems where prey species are available.

Range

Found across Europe (6 countries).

Quendelseide

Clover dodder (Cuscuta epithymum) is a parasitic flowering plant in the family Convolvulaceae, a leafless, twining vine that obtains all its water and nutrients from host plants via haustoria — specialized penetrating organs that connect to host vascular tissue. The species is almost entirely dependent on its hosts throughout its life, with only brief photosynthetic activity during germination before establishing parasitic connections. C. epithymum parasitizes a wide range of host species including clover (Trifolium), gorse (Ulex), heathers (Erica, Calluna), thyme (Thymus), and other plants in open heathland, grassland, and scrub habitats. The stems are thread-like, yellowish-pink or reddish, and support clusters of small white to pale pink flowers. Originally widespread across Europe, Asia, North Africa, and the Americas, the species has declined significantly in many parts of its range due to agricultural intensification, herbicide application, grassland conversion, and loss of semi-natural heathlands. It is currently listed as Endangered on the IUCN Red List, reflecting population decline across its European core range. Conservation of C. epithymum requires the maintenance of unimproved, low-nutrient grasslands and heathlands that support its diverse host plant communities. The species is recorded from Africa, Europe, North America, Oceania, and South America, though populations in some regions represent introductions associated with contaminated legume seed lots.

Graureiher

A large, elegant wading bird reaching up to 1 meter in height, gray herons inhabit wetlands, rivers, lakes, and coastal areas across Europe, Asia, and Africa. Patient, solitary hunters, they stand motionless for long periods before striking fish, frogs, and small mammals with lightning-fast dagger bill strikes. They nest colonially in tall trees in rookeries called heronries, sometimes shared with other colonial waterbirds. Widely distributed and of Least Concern globally.
