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 White Ash

Habitat

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

白头海雕

白头海雕是美国国鸟，也是美国生态保护史上的成功案例，曾因滴滴涕（DDT）的广泛使用而濒临灭绝，经保护措施的实施后种群数量已显著恢复。该物种在IUCN红色名录中被评估为无危（LC），以白色头颈和尾羽与深棕色体羽形成的鲜明对比为主要识别特征。它们主要以鱼类为食，也会捕食哺乳动物和腐肉。

Common White Ash

Bersama tysoniana, commonly known as the common white ash or Tyson's bersama, is a tree in the family Melianthaceae, native to southern Africa. It is classified as Least Concern by the IUCN. The species is found in forest margins, riverine woodland, and moist montane habitats within its native range on the African continent, where it typically grows as a small to medium-sized tree. Bersama tysoniana produces pinnately compound leaves with numerous leaflets, small white to cream-colored flowers arranged in terminal racemes, and distinctive capsular fruits that split to reveal seeds with fleshy orange-red arils. The arils are attractive to birds, which serve as the primary seed dispersers, facilitating natural regeneration within forest ecosystems. The wood is reportedly hard and durable, and the plant has been used in traditional medicine within its native range. Geographic range details and associated country records for this particular entry remain incompletely documented in available data sources. Biological traits including average lifespan, tree height, and mass remain poorly documented in standardized databases. Ecologically, Bersama tysoniana contributes to the structural complexity of southern African forest edge communities and supports a range of frugivorous birds and invertebrates through its fruit production, playing a modest but consistent role in forest food webs and seed dispersal networks.
