Guarea crispa

Declining

Overview

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

Guarea crispa faces severe pressure from deforestation and habitat fragmentation across its Atlantic Forest range in southeastern Brazil. The species is particularly vulnerable due to its restricted distribution and dependence on mature forest ecosystems that are being rapidly converted for agriculture, urban development, and logging. Climate change poses an additional threat by altering precipitation patterns and temperature regimes that this moisture-dependent tree species requires for successful reproduction and growth.

Threat summary

Habitat

Guarea crispa inhabits the Atlantic Forest (Mata Atlântica) of southeastern Brazil, typically found in humid lowland and montane forests at elevations up to 1,200 meters. The species requires well-drained soils and thrives in the understory and canopy of primary and mature secondary forests with high humidity and consistent rainfall.

Frequently asked questions

Why is Guarea crispa classified as Endangered?
Guarea crispa 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. Guarea crispa faces severe pressure from deforestation and habitat fragmentation across its Atlantic Forest range in southeastern Brazil. The species is particularly vulnerable due to its restricted distribution and dependence on mature forest ecosystems that are being rapidly converted for agriculture, urban development, and logging. Climate change poses an additional threat by altering precipitation patterns and temperature regimes that this moisture-dependent tree species requires for successful reproduction and growth.
Where does Guarea crispa live?
Guarea crispa occurs in Brazil, and Colombia. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Guarea crispa?
The main threats to Guarea crispa 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.
