Distributed across Cameroon and Guinea.
trinta-réis-boreal / gaivina
Found across multiple habitat types including tropical and subtropical dry broadleaf forests, flooded grasslands and savannas, and montane grasslands and shrublands, among 9 distinct biome types spanning the Neotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.
Widely distributed across Europe (7 countries), North America (United States), and South America (Colombia, Ecuador, Venezuela). Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.
Christmasbush
Christmasbush (Bursaria spinosa) is a native Australian shrub or small tree in the family Pittosporaceae, widely distributed across southeastern Australia. The species is found in a variety of habitats including dry sclerophyll woodland, grassland margins, and coastal heath, growing in well-drained soils. It produces dense clusters of small, fragrant white flowers typically in summer or early autumn, which coincide with the Australian Christmas season and give rise to one of its common names. The flowers are rich in nectar and attract a wide diversity of insects including native bees, butterflies, and beetles, making Bursaria spinosa one of the most ecologically significant flowering shrubs in southeastern Australian woodlands for invertebrate communities. The plant is also a critical larval host for several butterfly species, including the rare golden sun moth. Bursaria spinosa is a pioneering species in disturbed landscapes and is used in revegetation and ecological restoration projects. Its dense, thorny branches provide protective nesting habitat for small birds. The species tolerates poor soils and periods of drought once established. It has no significant conservation concerns and is common throughout its range.
