Habitat & Geographic Range

Basra Reed Warbler

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 5 distinct biome types within the Afrotropic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Kenya and Norway. Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Periwinkle

Habitat

Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Range

Widely distributed across Africa (South Africa), Asia (Armenia, Japan, Turkey), Europe (18 countries), North America (Canada, Mexico, United States), Oceania and the Pacific (Australia), and South America (Brazil).

Common Periwinkle

<em>Vinca minor</em>, known as the common periwinkle or lesser periwinkle, is a trailing evergreen subshrub in the family Apocynaceae, widely recognised by its glossy dark-green leaves and distinctive violet-blue, five-petalled flowers. Native to central and southern Europe, it has been extensively introduced and naturalised across a remarkably wide geographic range, with established populations documented across Africa, Asia, Europe, North America, Oceania, and South America, making it one of the more globally distributed ornamental escapees. The species typically colonises woodland edges, hedgerows, roadsides, and disturbed ground, often forming dense ground-covering mats that can suppress native vegetation. <em>Vinca minor</em> is tolerant of shade and a variety of soil types, contributing to its success as both a garden plant and an invasive species in some regions. It is assessed as Least Concern on the IUCN Red List given its vast distribution and adaptability. In many countries outside its native range, it is considered invasive. Biological traits such as average lifespan, precise growth dimensions, and detailed physiological parameters remain poorly documented in the scientific literature. The species contains alkaloids including vincamine, which have been investigated for pharmaceutical applications.
