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).

ciliate fringewort

Habitat

Native to Europe and North America, inhabiting ecosystems characteristic of the region.

Range

Found across 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.

ciliate fringewort

Ciliate fringewort (Ptilidium ciliare) is a leafy liverwort in the family Ptilidiaceae, found in boreal and montane regions of the Northern Hemisphere, including Europe, North America, and parts of northern Asia. It grows as a creeping, irregularly branched mat with leaves divided into deeply fringed lobes edged with long, hair-like cilia—the characteristic feature that gives the species its common name. Ciliate fringewort colonizes a variety of substrates including rock surfaces, boulders, tree trunks, and peaty ground in open to moderately shaded habitats such as heathland, moorland, montane grasslands, and subalpine and subarctic vegetation. It is particularly common on exposed rocks in boreal and tundra zones. The species is classified as Endangered in parts of Europe, where lowland populations have declined severely due to atmospheric nitrogen deposition, afforestation of open heathland, and the loss of traditionally managed heath and moorland habitats. Populations in montane and boreal zones remain more stable. Ciliate fringewort is sensitive to elevated nitrogen levels that promote the competitive dominance of grasses and mosses. Restoration of lowland heathland and reduction of nitrogen pollution are key measures needed to support remaining European populations. The species is better represented in Scandinavian boreal habitats and North American taiga and tundra.
