Habitat & Geographic Range

Ajuga

Habitat

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

Range

Widely distributed across Africa (South Africa), Asia (Japan), Europe (6 countries), North America (Canada, United States), Oceania and the Pacific (Australia, New Zealand), and South America (Brazil, Colombia). Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Coco yam

Coco Yam (Colocasia esculenta), also widely known as Taro, is a pantropical herbaceous plant in the family Araceae, cultivated as a food crop for more than 10,000 years and considered one of humanity's oldest cultivated plants. The species grows from large starchy corms and produces broad, sagittate leaves with distinctive water-repellent surfaces—an adaptation that has earned the plant its association with the lotus effect in traditional culture. Corms, cormels, and young leaves are all edible after thorough cooking, which is essential to neutralise the calcium oxalate crystals that cause intense irritation when raw. Originating in South and Southeast Asia, Colocasia esculenta has been dispersed across tropical Africa, the Pacific Islands, the Caribbean, and the Americas through centuries of agricultural exchange and migration. It thrives in wet or waterlogged soils, being particularly associated with paddy cultivation, irrigation channels, and swampy ground, though drought-tolerant cultivars exist. The species is a dietary staple in Hawaii, where it is the basis of poi; in West Africa, where it is boiled or pounded; and across the Pacific Islands, where it sustains subsistence communities. Given its widespread cultivation and genetic diversity represented across thousands of landraces, IUCN has not formally evaluated its conservation status. The species is not considered at risk.
