Pandanus aldabraensis

Unknown

Overview

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

Pandanus aldabraensis faces severe pressure from its extremely restricted range on Aldabra Atoll, where the entire population is confined to a single location making it highly vulnerable to catastrophic events. Invasive plant species compete for limited suitable habitat, while rising sea levels threaten the low-lying coastal areas where this endemic screw pine grows. Climate change-induced alterations to rainfall patterns and increased storm intensity pose additional risks to the species' long-term survival.

Threat summary

Habitat

This endemic screw pine is restricted to the coastal limestone terraces and inland plateaus of Aldabra Atoll in the Seychelles. It typically grows in well-drained coral sand soils and rocky crevices, often in association with other native vegetation in the atoll's unique raised coral island ecosystem.
