Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Manettia holwayi faces severe threats from ongoing deforestation and agricultural expansion within its extremely limited range in Costa Rica's montane forests. The species' restriction to a single location makes it exceptionally vulnerable to habitat destruction, with coffee cultivation and cattle ranching representing the primary drivers of forest conversion. Climate change poses an additional threat through potential shifts in the specific temperature and humidity conditions required by this endemic vine.
Habitat
This endemic vine is restricted to montane cloud forests in Costa Rica's central mountain ranges, typically occurring at elevations between 1,200-1,800 meters. It grows as an epiphytic or climbing species in the humid, moss-rich understory of primary and well-preserved secondary forests where consistent moisture and moderate temperatures prevail.
