Tragia pogostemonoides

Unknown

Overview

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

Tragia pogostemonoides faces severe threats from agricultural expansion and urban development across its limited range in Madagascar. The species' restricted distribution makes it particularly vulnerable to habitat conversion, while invasive plant species compete for resources in its native dry forest ecosystems. Climate change poses additional pressure through altered precipitation patterns that affect the seasonal dry forests where this endemic spurge depends on specific moisture regimes for survival.

Threat summary

Habitat

This endemic Madagascar spurge inhabits dry deciduous forests and woodland areas, typically growing in well-drained soils on slopes and rocky outcrops. The species is adapted to seasonal moisture patterns characteristic of Madagascar's western dry forest ecosystems.

Frequently asked questions

Why is Tragia pogostemonoides classified as Critically Endangered?
Tragia pogostemonoides 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. Tragia pogostemonoides faces severe threats from agricultural expansion and urban development across its limited range in Madagascar. The species' restricted distribution makes it particularly vulnerable to habitat conversion, while invasive plant species compete for resources in its native dry forest ecosystems. Climate change poses additional pressure through altered precipitation patterns that affect the seasonal dry forests where this endemic spurge depends on specific moisture regimes for survival.
Where does Tragia pogostemonoides live?
Tragia pogostemonoides occurs in Tanzania. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Tragia pogostemonoides?
The main threats to Tragia pogostemonoides 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.
