Quararibea ruiziana

Declining

Overview

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

Quararibea ruiziana faces severe population decline primarily due to extensive deforestation and agricultural conversion throughout its limited range in the Amazon basin. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, while selective logging targets the mature forest canopy where this tree species thrives. Climate change compounds these pressures by altering precipitation patterns essential for the species' reproductive cycles.

Threat summary

Habitat

Quararibea ruiziana inhabits primary lowland rainforests of the western Amazon basin, typically occurring in the upper canopy of mature forest stands. The species requires well-drained soils and consistent moisture levels characteristic of undisturbed tropical rainforest ecosystems.

Frequently asked questions

Why is Quararibea ruiziana classified as Critically Endangered?
Quararibea ruiziana 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. Quararibea ruiziana faces severe population decline primarily due to extensive deforestation and agricultural conversion throughout its limited range in the Amazon basin. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, while selective logging targets the mature forest canopy where this tree species thrives. Climate change compounds these pressures by altering precipitation patterns essential for the species' reproductive cycles.
Where does Quararibea ruiziana live?
Quararibea ruiziana 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 Quararibea ruiziana?
The main threats to Quararibea ruiziana 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.
