Styrax lasiocalyx

Declining

Overview

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

Styrax lasiocalyx faces severe population decline primarily due to extensive deforestation and agricultural conversion throughout its limited range in Southeast Asian montane forests. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, while logging operations targeting valuable timber species have degraded the forest canopy structure essential for its survival. Climate change poses an additional threat by altering the specific temperature and moisture conditions required in its montane habitat.

Threat summary

Habitat

Styrax lasiocalyx inhabits montane forests at elevations between 800-1,500 meters, typically found in the understory and forest edges of tropical evergreen forests. The species requires well-drained soils and the humid microclimate provided by intact forest canopy cover.

Frequently asked questions

Why is Styrax lasiocalyx classified as Critically Endangered?
Styrax lasiocalyx is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Styrax lasiocalyx faces severe population decline primarily due to extensive deforestation and agricultural conversion throughout its limited range in Southeast Asian montane forests. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, while logging operations targeting valuable timber species have degraded the forest canopy structure essential for its survival. Climate change poses an additional threat by altering the specific temperature and moisture conditions required in its montane habitat.
Where does Styrax lasiocalyx live?
Styrax lasiocalyx occurs in Colombia. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Styrax lasiocalyx?
The main threats to Styrax lasiocalyx are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
