Dendroseris macrantha

Unknown

Overview

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

Dendroseris macrantha faces severe threats from invasive plant species that outcompete native vegetation and alter soil chemistry on Juan Fernández Islands. Habitat degradation from introduced herbivores, particularly goats and rabbits, has severely reduced suitable growing areas. The species' extremely limited range makes it vulnerable to stochastic events and climate-related changes affecting the island's unique ecosystem.

Threat summary

Habitat

This endemic species inhabits the temperate rainforest and cloud forest zones of the Juan Fernández Islands, typically growing in moist, well-drained soils at elevations between 400-600 meters. It occurs in areas with high humidity and frequent fog, often associated with native Myrceugenia fernandeziana forests.
