Argythamnia macrantha
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Argythamnia macrantha faces severe threats from habitat destruction due to urban development and agricultural expansion across its limited range in Puerto Rico. The species' extremely restricted distribution makes it particularly vulnerable to localized disturbances, while invasive plant species compete for resources in its native dry forest habitat. Climate change poses additional risks through altered precipitation patterns that could further stress this already critically endangered shrub.
Habitat
This endemic Puerto Rican shrub inhabits dry limestone forests and coastal scrublands, typically growing on well-drained calcareous soils in areas with seasonal rainfall patterns. It occurs in remnant patches of subtropical dry forest ecosystem that once covered much of Puerto Rico's southern coastal plains.
