Alternanthera helleri
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Alternanthera helleri faces severe pressure from urban development and agricultural expansion across its limited range in the Galápagos Islands. The species is particularly vulnerable to habitat degradation from introduced grazing animals, especially goats and cattle, which trample and consume native vegetation. Competition from aggressive invasive plant species further threatens remaining populations by displacing this endemic herb from its preferred coastal and lowland habitats.
Habitat
This endemic Galápagos herb inhabits coastal zones, dry lowland areas, and disturbed sites on several islands in the archipelago. It typically grows in sandy soils and rocky areas near the shore, often in association with other native coastal vegetation.
