Peruvian ragweed

Ambrosia cumanensis

Unknown

Overview

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

Ambrosia cumanensis faces severe pressure from rapid coastal development and tourism infrastructure expansion across Trinidad and Tobago's limited suitable habitat. Agricultural conversion and urban sprawl have fragmented remaining populations, while invasive plant species compete for resources in disturbed areas. Climate change poses additional risks through altered precipitation patterns and increased storm intensity affecting coastal zones where this species persists.
