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).

Coastal Mahoe

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。

Coastal Mahoe

Melicytus novae-zelandiae, the coastal mahoe, is a shrub or small tree in the family Violaceae native to New Zealand, where it occurs along the coastlines of both the North and South Islands, extending to some offshore islands. The mahoes are a characteristic group of small trees and shrubs in the New Zealand flora, and M. novae-zelandiae is distinguished as the coastal ecotype of this group, tolerating salt spray, coastal winds, and the harsh conditions of maritime scrub and coastal forest margins. The species typically reaches 2–6 meters in height and produces small, yellowish-green flowers followed by fleshy purple to black fruits that are eaten by native birds including silvereyes, bellbirds, and tuis that disperse seeds through coastal scrub. Coastal mahoe provides important food and shelter resources in coastal bird habitats. Like other New Zealand violets in Melicytus, the plants are dioecious, with separate male and female individuals. The species is classified as Least Concern by the IUCN, being a naturally common component of coastal New Zealand vegetation and capable of persisting in modified coastal habitats including regenerating scrub and planted gardens. It is used in coastal revegetation and gardening for its wind and salt spray tolerance.
