Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Taiwan), Europe (4 countries), and South America (Colombia, Ecuador). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Velvetgrass

Habitat

Typically found in grasslands, wetlands, forests, and cultivated landscapes.

Range

藍鯨

蓝鲸是地球上已知存在过的最大动物，体长可达33米，体重达200吨，其心脏单独就重达一辆小型轿车的重量。分布于各大洋，在极地觅食地和热带繁殖地之间进行迁徙。它们是滤食性动物，每日可消耗多达4吨磷虾。蓝鲸被列为濒危物种，20世纪捕鲸活动使其濒临灭绝，目前全球种群估计约为1万至2.5万头。

Common Velvetgrass

<em>Holcus lanatus</em>, commonly known as common velvetgrass or Yorkshire fog, is a perennial grass in the family Poaceae native to Europe and western Asia that has become widely naturalized across temperate regions of North America, South America, New Zealand, and Australia. The species derives its common name from the soft, velvety texture of its leaves and stems, produced by a dense covering of fine hairs. <em>Holcus lanatus</em> typically grows in moist meadows, pastures, roadsides, forest clearings, and disturbed habitats, tolerating a wide range of soil conditions from acidic to neutral and from moist to moderately dry. It forms loose tufts with erect or spreading culms reaching up to 100 centimeters in height, topped with soft, pinkish-gray panicles during the summer flowering period. In its introduced range, particularly in New Zealand and parts of North America, velvetgrass is considered an invasive weed that displaces native plant communities in pastures and natural areas. The species is also known to cause allergic reactions in sensitive individuals due to its wind-dispersed pollen. <em>Holcus lanatus</em> is currently assessed as Least Concern by the IUCN. Its populations are abundant and expanding globally. Biological traits such as average individual lifespan, precise culm height ranges, and seed output per plant remain variable and poorly documented at the individual level.
