Aloe decorsei

Unknown

Overview

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

Aloe decorsei faces severe population decline primarily due to habitat destruction from agricultural expansion and charcoal production in Madagascar's dry forests. The species is further threatened by overcollection for horticultural trade, as its distinctive appearance makes it highly sought after by succulent collectors. Climate change exacerbates these pressures by altering precipitation patterns in its already arid habitat.

Threat summary

Habitat

Aloe decorsei is endemic to the dry deciduous forests and spiny thickets of southwestern Madagascar, typically growing on rocky outcrops and limestone substrates. The species thrives in arid conditions with well-drained soils and is adapted to the region's pronounced dry season.

Frequently asked questions

Why is Aloe decorsei classified as Critically Endangered?
Aloe decorsei 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. Aloe decorsei faces severe population decline primarily due to habitat destruction from agricultural expansion and charcoal production in Madagascar's dry forests. The species is further threatened by overcollection for horticultural trade, as its distinctive appearance makes it highly sought after by succulent collectors. Climate change exacerbates these pressures by altering precipitation patterns in its already arid habitat.
Where does Aloe decorsei live?
Aloe decorsei occurs in Madagascar. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Aloe decorsei?
The main threats to Aloe decorsei are 2.3, ai-1, ai-2, and ai-3. The full IUCN-classified threat record for this species is detailed on the species page.
