Scalesia microcephala
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Scalesia microcephala faces severe pressure from invasive plant species that outcompete native vegetation and alter ecosystem dynamics across its limited range. Habitat degradation from introduced herbivores, particularly goats and cattle, has fragmented remaining populations through trampling and overgrazing. The species' restricted distribution on specific volcanic slopes makes it extremely vulnerable to stochastic events and climate-driven habitat shifts.
Habitat
This endemic Galápagos shrub occupies humid highland zones on volcanic slopes, typically found in transitional areas between arid lowlands and moist upland forests. It grows in well-drained volcanic soils at elevations where fog and occasional rainfall support specialized endemic plant communities.
