Costus muluensis

Stable

Overview

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

Costus muluensis faces severe pressure from deforestation and habitat conversion in its limited range within Borneo's montane forests. The species' restricted distribution makes it particularly vulnerable to logging activities and agricultural expansion, while its specialized habitat requirements limit its ability to adapt to environmental changes. Climate change poses an additional threat by potentially altering the moisture and temperature conditions essential for this tropical ginger's survival.

Threat summary

Habitat

Costus muluensis inhabits the understory of primary and secondary montane rainforests in Borneo, typically occurring at elevations between 800-1,500 meters. The species thrives in humid, shaded environments with rich, well-drained soils characteristic of tropical mountain forest ecosystems.
