Erithalis quadrangularis
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Erithalis quadrangularis faces severe pressure from coastal development and tourism infrastructure expansion across its Caribbean range. The species' restricted distribution to coastal limestone areas makes it particularly vulnerable to habitat conversion for resorts and residential developments. Rising sea levels and increased storm intensity associated with climate change pose additional threats to its low-lying coastal habitats.
Habitat
This Caribbean endemic shrub inhabits coastal limestone areas, rocky shores, and dry coastal forests throughout the Greater and Lesser Antilles. It typically grows in well-drained calcareous soils near the coast, often in areas exposed to salt spray and strong winds.
