Oleandra hainanensis

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Oleandra hainanensis faces severe pressure from rapid deforestation and habitat conversion across its limited range in Hainan Island's tropical forests. The species' restricted distribution makes it particularly vulnerable to localized threats, with remaining populations fragmented by agricultural expansion and urban development. Climate change poses an additional threat through altered precipitation patterns that could affect the humid forest conditions this fern requires.

Threat summary

Habitat

This endemic fern inhabits the understory of tropical rainforests and moist montane forests on Hainan Island, typically growing in shaded areas with high humidity and rich, well-drained soils. It is found at elevations ranging from lowland forests to mid-elevation slopes where consistent moisture levels support its growth requirements.
