Lasianthus grandifolius

Unknown

Overview

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

Lasianthus grandifolius faces severe pressure from deforestation and agricultural expansion across its limited range in Southeast Asian montane forests. The species' restriction to specific elevation zones makes it particularly vulnerable to habitat fragmentation, as remaining forest patches become increasingly isolated. Mining activities and infrastructure development in mountainous regions further threaten the specialized understory environments this species requires for survival.

Threat summary

Habitat

This species inhabits the understory of tropical montane forests, typically occurring at elevations between 800-1,800 meters in humid, shaded environments. It grows in well-drained soils along forest slopes and ridges where canopy cover provides consistent moisture and protection from direct sunlight.
