Magnolia gustavii

Declining

Overview

Magnolia gustavii is a species of flowering plant in the family Magnoliaceae. It is native to the Assam region, Myanmar and Thailand.

Magnolia gustavii faces severe threats from deforestation and habitat conversion for agriculture and development across its limited range in the Caribbean. The species' extremely small population size makes it vulnerable to stochastic events and genetic bottlenecks. Climate change poses additional risks through altered precipitation patterns and increased hurricane intensity, which can devastate the remaining fragmented populations.

Threat summary

Habitat

This critically endangered magnolia inhabits moist tropical forests and woodland areas in the Caribbean region. It typically grows in well-drained soils at moderate elevations where it benefits from consistent moisture and partial canopy protection.

Frequently asked questions

Why is Magnolia gustavii classified as Critically Endangered?
Magnolia gustavii 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. Magnolia gustavii faces severe threats from deforestation and habitat conversion for agriculture and development across its limited range in the Caribbean. The species' extremely small population size makes it vulnerable to stochastic events and genetic bottlenecks. Climate change poses additional risks through altered precipitation patterns and increased hurricane intensity, which can devastate the remaining fragmented populations.
Where does Magnolia gustavii live?
Magnolia gustavii occurs in India, Myanmar (Burma), and Thailand. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Magnolia gustavii?
The main threats to Magnolia gustavii are 2.1, 5.3, ai-1, and ai-2. The full IUCN-classified threat record for this species is detailed on the species page.
