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 Moonwort

Habitat

Typically found in moist, shaded forest floors and tropical canopies.

Range

Widely distributed across Asia (Taiwan), Europe (5 countries), and North America (United States). Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

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 Moonwort

Common Moonwort (<em>Botrychium lunaria</em>) is a small fern in the genus <em>Botrychium</em>, family Ophioglossaceae. It is distributed across Asia, Europe, and North America, with confirmed presence in Belgium, Denmark, Norway, Portugal, and Sweden, as well as Taiwan and the United States. The species is typically found in moist, shaded forest floors and tropical canopies. Common Moonwort is currently classified as Endangered on the IUCN Red List, indicating that it faces significant conservation challenges across its range. Its distinctive frond is divided into two parts: a sterile fan-shaped leaf portion with rounded lobes resembling a crescent moon, and a fertile spike bearing spore-bearing structures. As a fern ally rather than a flowering plant, it reproduces via spores rather than seeds. The species is associated with stable, undisturbed habitats including ancient grasslands, upland heaths, and rocky slopes. Its sensitivity to habitat disturbance and changes in land management are thought to contribute to population declines. Specific biological measurements such as lifespan and dimensions are not documented in available records.
