Verbesina biserrata

Declining

Overview

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

Verbesina biserrata faces severe population decline due to extensive habitat conversion for agricultural development and urban expansion across its limited range. The species' restricted distribution makes it particularly vulnerable to localized threats, with remaining populations fragmented by human activities. Invasive plant species compete directly with this native composite for resources and growing space, further reducing available habitat quality.

Threat summary
