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 Water-Parsnip

Habitat

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

Range

Distributed across Canada, Mexico, Norway, Taiwan, and United States.

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 Water-Parsnip

<em>Sium suave</em>, commonly known as the common water parsnip or hemlock water parsnip, is a perennial wetland herb in the family Apiaceae. It is classified as Least Concern by the IUCN and is distributed across a wide geographic range that includes Canada, the United States, Mexico, Norway, and Taiwan, reflecting its adaptability to temperate and subtropical freshwater margins. The species typically grows in marshes, wet meadows, stream banks, and shallow water, rooting in saturated soils with stems partially submerged. It produces pinnately compound leaves with serrated leaflets and bears flat-topped white flower clusters called umbels in mid to late summer. <em>Sium suave</em> can reach heights of one to two meters and is often found in dense stands along slow-moving waterways. Despite its common name suggesting edibility, the plant contains toxic alkaloids and should not be consumed. The roots are particularly toxic and have been historically confused with edible water parsnip, posing a risk to foragers. Biological traits including average lifespan, stem height details, and mass remain poorly documented in standardized databases. Ecologically, common water parsnip provides nesting and foraging cover for wetland birds and mammals, and its umbel flowers attract a diversity of pollinators. The plant plays a structural role in freshwater riparian plant communities across its broad North American and Eurasian distribution.
