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).

Compact brome

Habitat

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

Range

Widely distributed across Africa (South Africa), Asia (Japan), Europe (15 countries), North America (Mexico, United States), Oceania and the Pacific (Australia), and South America (Chile).

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.

Compact brome

<em>Bromus madritensis</em>, compact brome or Madrid brome, is an annual grass in the family Poaceae with an expansive native distribution across the Mediterranean basin, extending into parts of Africa, the Middle East, and central Asia. It has also been widely introduced to North America, South America, Australia, and other regions, where it is often considered an invasive weed in disturbed grasslands and shrublands. The species grows typically to 15–50 centimetres in height, producing dense, compact panicles with characteristic bristle-tipped spikelets that aid seed dispersal by attachment to passing animals and clothing. It thrives in dry, disturbed habitats including roadsides, agricultural margins, coastal scrub, and degraded grasslands, demonstrating strong tolerance for poor soils and seasonal drought. Compact brome is a pioneer species that colonises bare ground rapidly and can outcompete native herbaceous vegetation in fragile ecosystems, particularly in California chaparral and Mediterranean-climate shrublands. It is Not Evaluated on the IUCN Red List, consistent with its abundance and broad distribution. The species completes its life cycle entirely within a single growing season, germinating in autumn or winter and setting seed by late spring. Biological traits including precise lifespan data are inherent to its annual habit, but additional morphological and population data remain variable across its wide geographic range.
