Habitat & Geographic Range

Weißkopf-Seeadler

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and flooded grasslands and savannas, among 10 distinct biome types spanning the Neotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Europe (8 countries), North America (United States), and South America (Ecuador).

Coastal Bastard Toad-flax

Habitat

Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Weißkopf-Seeadler

The national bird of the United States and a symbol of American conservation success, bald eagles have a wingspan of up to 2.4 meters and inhabit forests and wetlands near open water across North America. Powerful aerial predators and scavengers, they specialize in fish but also take waterfowl and carrion. Nearly extinct by the 1960s due to DDT poisoning and hunting, the bald eagle recovered dramatically following pesticide bans and the Endangered Species Act.

Coastal Bastard Toad-flax

Thesium maritimum, the coastal bastard toad-flax, is a semi-parasitic herbaceous plant in the family Santalaceae native to coastal sand dunes, calcareous grassland, and scrubland along the northern Mediterranean coast of Europe, extending through the Iberian Peninsula and into parts of southwestern France. Like other members of the genus Thesium, it is a hemiparasite, maintaining chlorophyll and photosynthesizing while simultaneously tapping the root systems of neighboring grasses and herbs to extract water and nutrients through haustorial connections. The species produces small, narrow leaves and inconspicuous white to cream flowers typical of the family, lacking showy petals and relying on insect visitors for pollination. Thesium maritimum is classified as Vulnerable by the IUCN, reflecting significant population declines associated with loss and degradation of its specialized coastal habitat through tourist infrastructure development, coastal stabilization, invasive species encroachment, and sand dune fixation. Mediterranean coastal sand dune systems across Europe have been extensively modified, and the open, dynamic habitats required by this specialist species have contracted substantially over recent decades. Conservation measures include dune restoration, reduction of vehicle traffic on coastal habitats, and control of invasive species that fix and stabilize natural shifting sands.
