Habitat & Geographic Range

Coastal Dendrobium

Habitat

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

Common Kidney-Vetch

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, temperate broadleaf and mixed forests, and temperate coniferous forests, among 6 distinct biome types spanning the Indomalayan and Oceanian and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Libya), Asia (Japan), Europe (9 countries), North America (Canada, United States), and Oceania and the Pacific (Australia). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Coastal Dendrobium

Dendrobium litorale, the coastal dendrobium, is an epiphytic orchid in the family Orchidaceae native to lowland coastal forests and mangrove margins across the Pacific island region, including Papua New Guinea, the Solomon Islands, and adjacent island groups. The genus Dendrobium is one of the largest in the Orchidaceae, comprising over 1,800 described species distributed from tropical Asia through Australasia and the Pacific, and includes numerous horticulturally important species cultivated worldwide. Dendrobium litorale grows as an epiphyte attached to tree branches and trunks in humid coastal forest environments, including forest-mangrove transition zones subject to salt spray and tidal influence that few other orchids can tolerate. The pseudobulbs store water and nutrients, enabling survival during intermittent dry periods. Flowers are typically small to medium-sized with white or pale coloring and complex labellum structures that guide pollinators, often specific bee species, into contact with pollen. The species is classified as Least Concern by the IUCN. Coastal lowland forests across the Pacific face significant ongoing pressure from logging, oil palm conversion, and human settlement expansion, threatening the specific forest-mangrove habitats this coastal orchid requires.

Common Kidney-Vetch

Common Kidney-Vetch (<em>Anthyllis vulneraria</em>) is a flowering plant in the legume family Fabaceae, assessed as Vulnerable on the IUCN Red List due to habitat degradation and agricultural intensification across parts of its range. It is widely distributed across Africa (Libya), Asia (Japan), Europe (nine countries), North America (Canada and the United States), and Oceania (Australia), occupying six distinct biome types and occurring within the Indomalayan and Oceanian biogeographic realms. The species typically grows in dry, calcareous grasslands, coastal cliffs, sand dunes, and rocky slopes, often favoring nutrient-poor soils. It is an important larval food plant for certain butterfly species, particularly the Small Blue butterfly in Europe, and contributes to soil fertility through nitrogen fixation via root nodules. Its cheerful yellow, orange, or red flower heads make it a recognizable component of chalk and limestone grassland communities. Biological traits of this species remain poorly documented in the scientific literature.
