Pisonia graciliscens

Unknown

Overview

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

Pisonia graciliscens faces severe threats from habitat destruction due to coastal development and tourism infrastructure expansion across its limited range. The species is particularly vulnerable to invasive plant species that outcompete native vegetation and alter soil chemistry. Climate change poses additional risks through sea-level rise and increased storm intensity affecting coastal forest ecosystems where this endemic tree occurs.
Threat summary

Habitat

Pisonia graciliscens inhabits coastal forests and littoral woodlands, typically growing in sandy soils near shorelines and in low-elevation tropical forest margins. The species is adapted to salt-tolerant conditions and occurs in areas with high humidity and seasonal rainfall patterns.
