Habitat & Geographic Range

Common teatree

Habitat

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

Range

Distributed across Congo (DRC) and United States.

Laysan Duck

Habitat

Found across multiple habitat types including temperate broadleaf and mixed forests, temperate coniferous forests, and Mediterranean forests and woodlands within the Palearctic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Belgium, France, Netherlands, Norway, and United Kingdom. Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Common teatree

<em>Leptospermum petersonii</em>, the lemon-scented teatree, is a shrub or small tree in the family Myrtaceae, native to eastern Australia but noted in distribution records including the Democratic Republic of Congo and the United States, reflecting its cultivation and occasional naturalization in tropical and subtropical regions. It is classified as Least Concern on the IUCN Red List. The plant is prized for its strongly lemon-scented foliage, which yields an essential oil used in perfumery and aromatherapy. It typically grows as a dense, multi-stemmed shrub reaching 3–6 meters tall, bearing small, narrow leaves and white or pale pink five-petaled flowers. Like other teatrees, it is adapted to well-drained, often nutrient-poor soils and full sun conditions. The flowers attract bees and other pollinators. It is sometimes cultivated as an ornamental and for essential oil production. Biological traits such as precise lifespan, seed output, and biomass measurements remain poorly documented in standardized scientific assessments for this species.

Laysan Duck

Laysan Duck (Anas laysanensis) is classified as Critically Endangered (CR) on the IUCN Red List. Facing an extremely high risk of extinction in the wild due to severe population decline and habitat loss.
