Habitat & Geographic Range

American Bald Eagle

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).

Cliff Hair Grass

Habitat

Typically found in grasslands, wetlands, forests, and cultivated landscapes.

American Bald Eagle

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.

Cliff Hair Grass

Cliff Hair-grass, Deschampsia cespitosa subsp. or related species within the Poaceae, is a tufted perennial grass adapted to moist, rocky cliff habitats, stream banks, and alpine or subalpine meadows in temperate mountain regions of Europe and North America. The genus Deschampsia, the hair-grasses, includes delicate, fine-leaved grasses with elegant, open panicles of tiny, often silvery or purplish spikelets that catch the light in mountain settings. Cliff-dwelling forms occupy ledges, crevices, and rocky terraces on cliff faces, benefiting from the stability provided by the cliff substrate and reduced competition from larger plants. The leaves are narrow, rough-edged, and rigid, adapted to exposed, windy conditions. Hair-grasses form dense clumps or tussocks that stabilize thin cliff soils and provide habitat for invertebrates. The species is widespread in cool, moist montane habitats across the Northern Hemisphere and is generally not considered threatened. It tolerates a wide range of soil chemistry and is among the first grasses to colonize disturbed mountain terrain. Deschampsia species play important roles in alpine ecosystem dynamics, including interactions with soil crust communities and montane invertebrate fauna.
