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).

Common Larch

Habitat

Typically found in temperate and boreal forests, often at higher elevations.

Range

Widely distributed across Asia (Armenia, Turkey), Europe (18 countries), North America (Canada, United States), and Oceania and the Pacific (New Zealand).

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。

Common Larch

Common Larch (<em>Larix decidua</em>) is a deciduous conifer in the family Pinaceae, distinguished among conifers by its seasonal needle drop. Its native range spans Asia (Armenia and Turkey), eighteen European countries, North America (Canada and the United States), and Oceania (New Zealand), encompassing a broad latitudinal range across temperate and boreal zones. The species typically inhabits temperate and boreal forests, often at higher elevations in montane and subalpine zones where it tolerates cold, short growing seasons and well-drained mineral soils. Common Larch is an important timber tree and is widely planted in forestry and as an ornamental species. Its golden autumn foliage is a distinctive feature of mountain landscapes in the Alps and Carpathians. The conservation status of this species has not been formally evaluated by the IUCN. It plays an ecological role in structuring montane forest communities and providing habitat for numerous associated species. Biological traits of this species remain poorly documented in the scientific literature.
