Hibiscus scottii

Unknown

Overview

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

Hibiscus scottii faces severe pressure from habitat destruction as coastal development and agricultural expansion fragment its limited native range in Hawaii. Invasive plant species compete aggressively for resources, while feral ungulates trample and browse the remaining wild populations. Climate change poses an additional threat through altered precipitation patterns and increased storm intensity affecting this coastal endemic.
