Habitat & Geographic Range

ハクトウワシ

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).

Cobble Forget-me-not

Habitat

Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

ハクトウワシ

アメリカの国鳥であり保全の成功を象徴するハクトウワシは翼開長が最大2.4 mに達し、北米全域の水辺近くの森林や湿地に生息する。強力な空中捕食者兼腐肉食者で魚を主食とするが、水鳥や腐肉も捕食する。DDT汚染と狩猟によって1960年代にほぼ絶滅に瀕したが、農薬の使用禁止と絶滅危惧種法の施行により劇的に回復した。

Cobble Forget-me-not

Cobble forget-me-not (Myosotis schistosa) is a small annual or biennial herb in the family Boraginaceae, native to riverine and coastal habitats in parts of Europe, particularly associated with slate, shale, or schist substrates and disturbed gravelly or rocky ground. Like other Myosotis species, it bears the typical small, five-petalled blue flowers with a yellow eye that give forget-me-nots their widespread recognition. The genus Myosotis encompasses dozens of species distributed across Europe, Asia, North America, and the Southern Hemisphere, many of which are adapted to specific, often nutrient-poor or geologically specialised substrates. Cobble forget-me-not is assessed as Data Deficient by the IUCN, reflecting limited information on its distribution, population size, and ecology. Botanical surveys in appropriate habitats across its inferred range—particularly slate-rich riverbanks and coastal cobble in Europe—are needed to clarify its taxonomy, distribution, and conservation requirements. Like many small annual herbs in disturbed habitats, it may be locally common in suitable microsites but easily overlooked due to its small size and annual habit.
