Gardenia pterocalyx

Declining

Overview

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

Gardenia pterocalyx faces severe pressure from deforestation and agricultural expansion across its limited range in Southeast Asian tropical forests. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, while selective logging targets the mature forest canopy where this gardenia typically establishes. Climate change poses an additional threat through altered precipitation patterns that could disrupt the specific moisture conditions this species requires for reproduction.

Threat summary

Habitat

Gardenia pterocalyx inhabits the understory and mid-canopy of primary tropical rainforests, typically found in areas with consistent moisture and well-drained soils. The species shows preference for mature forest ecosystems with established canopy cover that provides the filtered light conditions essential for its growth.

Frequently asked questions

Why is Gardenia pterocalyx classified as Endangered?
Gardenia pterocalyx is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Gardenia pterocalyx faces severe pressure from deforestation and agricultural expansion across its limited range in Southeast Asian tropical forests. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, while selective logging targets the mature forest canopy where this gardenia typically establishes. Climate change poses an additional threat through altered precipitation patterns that could disrupt the specific moisture conditions this species requires for reproduction.
Where does Gardenia pterocalyx live?
Gardenia pterocalyx occurs in Indonesia, and Malaysia. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Gardenia pterocalyx?
The main threats to Gardenia pterocalyx 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.
