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.

Águila cabeza blanca

El ave nacional de los Estados Unidos y símbolo del éxito conservacionista americano, el águila cabeza blanca tiene una envergadura de hasta 2,4 metros y habita bosques y humedales próximos a aguas abiertas en toda Norteamérica. Casi extinta en la década de 1960 por el envenenamiento con DDT y la caza, se recuperó de forma notable gracias a las prohibiciones de pesticidas y la Ley de Especies en Peligro.

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.
