Alternanthera snodgrassii

Unknown

Overview

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

Alternanthera snodgrassii faces severe pressure from invasive plant species that outcompete it for limited coastal habitat resources in the Galápagos Islands. Introduced herbivores, particularly goats and cattle, have degraded its native beach and coastal scrubland habitats through overgrazing and trampling. Tourism development and associated infrastructure construction continue to fragment and reduce the species' already restricted range across its endemic island locations.

Threat summary

Habitat
