Habitat & Geographic Range

Chives

Habitat

Inhabits tropical and subtropical moist broadleaf forests and temperate coniferous forests spanning the Oceanian and Palearctic realms.

Range

Widely distributed across Africa (Algeria, Seychelles), Asia (Taiwan), Europe (14 countries), North America (United States), Oceania and the Pacific (Tuvalu), and South America (Brazil, Colombia).

Common Silver Hairgrass

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical grasslands and savannas, and flooded grasslands and savannas, among 11 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Cameroon), Asia (Japan, South Korea), Europe (6 countries), North America (4 countries), Oceania and the Pacific (Australia), and South America (4 countries). Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Chives

Chives (Allium schoenoprasum) are a perennial bulb-forming herb in the family Amaryllidaceae, widely distributed across temperate regions of Europe, Asia, and North America. They represent the smallest species in the genus Allium, which also includes onions, garlic, and leeks, and are the only Allium species native to both the Old and New Worlds. Chives produce slender, hollow, cylindrical leaves and round, pale purple to lilac flower heads atop leafless stalks, both of which are edible and valued for their mild onion flavour. In the wild, chives grow in a range of habitats including rocky slopes, mountain meadows, riverbanks, and forest edges, typically preferring cool, moist conditions with well-drained soils. They spread both by seed and by vegetative division of their bulb clumps, forming dense patches. As one of the classic fines herbes of French cuisine, chives have been cultivated for culinary use for over 5,000 years and are now grown worldwide in gardens and as a commercial crop. The flowers are also attractive to bees and other pollinators. The IUCN classifies Allium schoenoprasum as Least Concern, with widespread natural populations throughout its native range. While not threatened globally, localised populations may be affected by habitat loss or overgrazing in alpine or subalpine settings.

Common Silver Hairgrass

<em>Aira caryophyllea</em>, commonly known as Common Silver Hairgrass, is a slender annual grass belonging to the family Poaceae within the order Poales. This delicate grass is currently classified as Endangered on the IUCN Red List, reflecting significant conservation concern despite its historically broad distribution. It is typically found across a remarkable diversity of biome types, including tropical and subtropical moist broadleaf forests, grasslands, savannas, and flooded habitats, demonstrating notable ecological versatility. Its geographic range spans multiple continents, with documented populations in Africa (Cameroon), Asia (Japan, South Korea), Europe, North America, Australia, and South America. As an annual grass, it completes its life cycle within a single growing season, reproducing via wind-dispersed seeds. The inflorescence typically bears silvery, shimmering spikelets that give the species its common name. Biological traits such as average lifespan, body dimensions, and dietary specifics follow typical patterns for annual grasses — drawing nutrients from soil through root absorption rather than consuming other organisms. The endangered status suggests populations may be declining due to habitat loss, land-use change, or invasive species pressure across parts of its range.
