Cyanea solenocalyx

Unknown

Overview

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

Cyanea solenocalyx faces severe pressure from invasive plant species that outcompete native vegetation and alter forest understory conditions essential for its survival. Habitat degradation from feral ungulates, particularly pigs and goats, damages the delicate forest floor ecosystems where this endemic Hawaiian lobelioid thrives. Climate change poses an additional threat through altered precipitation patterns and temperature shifts that affect the cool, moist montane forests this species requires.

Threat summary

Habitat

Cyanea solenocalyx inhabits cool, moist montane forests in Hawaii, typically found in understory environments with rich organic soils and consistent moisture levels. The species requires specific microhabitat conditions including filtered sunlight and protection from strong winds, making it highly dependent on intact native forest ecosystems.
