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).

Common Velvetgrass

Habitat

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

Range

Widely distributed across Africa (5 countries), Asia (6 countries), Europe (8 countries), North America (4 countries), Oceania and the Pacific (Australia, New Zealand), and South America (5 countries).

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.

Common Velvetgrass

<em>Holcus lanatus</em>, commonly known as common velvetgrass or Yorkshire fog, is a perennial grass in the family Poaceae native to Europe and western Asia that has become widely naturalized across temperate regions of North America, South America, New Zealand, and Australia. The species derives its common name from the soft, velvety texture of its leaves and stems, produced by a dense covering of fine hairs. <em>Holcus lanatus</em> typically grows in moist meadows, pastures, roadsides, forest clearings, and disturbed habitats, tolerating a wide range of soil conditions from acidic to neutral and from moist to moderately dry. It forms loose tufts with erect or spreading culms reaching up to 100 centimeters in height, topped with soft, pinkish-gray panicles during the summer flowering period. In its introduced range, particularly in New Zealand and parts of North America, velvetgrass is considered an invasive weed that displaces native plant communities in pastures and natural areas. The species is also known to cause allergic reactions in sensitive individuals due to its wind-dispersed pollen. <em>Holcus lanatus</em> is currently assessed as Least Concern by the IUCN. Its populations are abundant and expanding globally. Biological traits such as average individual lifespan, precise culm height ranges, and seed output per plant remain variable and poorly documented at the individual level.
