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 Woodrush

Habitat

Inhabits tropical and subtropical moist broadleaf forests within the Neotropic biogeographic realm.

Range

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 Woodrush

<em>Luzula campestris</em>, the common woodrush or field woodrush, is a small perennial plant in the family Juncaceae. It is widespread across Europe, western Asia, and northern Africa, with naturalized populations established in parts of North America and other temperate regions. The species typically colonizes short grasslands, heathlands, lawns, roadside verges, and open woodland clearings, preferring slightly acidic, well-drained soils with low nutrient levels. Plants form low, tufted rosettes of narrow, grass-like leaves fringed with long white hairs, a diagnostic feature of the genus. Flowering stems reach 5–30 cm and bear nodding, chestnut-brown flower clusters in early spring, making it one of the earlier flowering grassland plants. Biological traits such as precise lifespan, body dimensions, and detailed weight data remain poorly documented at the species level. <em>Luzula campestris</em> is an important indicator of ancient, unimproved grassland habitats in Britain and Europe, and its presence is often associated with high botanical diversity. It is assessed as Least Concern, reflecting stable populations across its native range, though localized declines may occur where intensive agriculture reduces suitable habitat.
