Habitat & Geographic Range

Common Mint

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical coniferous forests, among 4 distinct biome types within the Indomalayan biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Seychelles), Asia (4 countries), Europe (10 countries), North America (Canada, United States), and South America (Brazil).

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.

Common Mint

Common Mint (<em>Mentha arvensis</em>), also known as corn mint or field mint, is a perennial herbaceous plant in the genus <em>Mentha</em>, family Lamiaceae. It is widely distributed across Africa, Asia, Europe, North America, and South America, with confirmed presence in countries including Belarus, Belgium, Brazil, Canada, and Czech Republic. Its range encompasses the Seychelles in Africa, four Asian countries, and ten European nations. The species is found across multiple habitat types, including tropical and subtropical moist broadleaf forests, dry broadleaf forests, and coniferous forests, occurring within at least four distinct biome types in the Indomalayan realm. Common Mint is classified as Least Concern on the IUCN Red List. As a member of the mint family, it typically produces aromatic foliage rich in menthol, and has historically been used in culinary and medicinal applications across many cultures. It typically spreads vegetatively through stolons and rhizomes in addition to producing seed. Detailed measurements of lifespan, length, and weight are not documented in available records.

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.
