Calycorectes wurdackii

Declining

Overview

Eugenia wurdackii is a species of flowering plant in the family Myrtaceae. It is a tree endemic to northeastern Peru. It grows up to 25 metres tall. It is native to a small area along the banks of the Santiago River in Amazonas Department, near the Santiago-Comaina Reserved Zone, where it grows in lowland Amazon Rainforest from 300 to 350 metres elevation. The species is threatened by habitat loss from deforestation caused by gold mining.

Calycorectes wurdackii faces severe threats from ongoing deforestation and habitat fragmentation within its extremely limited range in the Atlantic Forest of Brazil. Agricultural expansion, particularly cattle ranching and crop cultivation, continues to reduce the remaining forest patches where this endemic species occurs. Urban development pressures and infrastructure projects further fragment the already restricted habitat, isolating small populations and reducing genetic diversity.

Threat summary

Habitat

This species is endemic to the Atlantic Forest (Mata Atlântica) of southeastern Brazil, occurring in humid lowland and montane rainforest remnants. It typically grows in the understory and canopy of primary and well-preserved secondary forests with high humidity and rich, organic soils.

Frequently asked questions

Why is Calycorectes wurdackii classified as Critically Endangered?
Calycorectes wurdackii 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. Calycorectes wurdackii faces severe threats from ongoing deforestation and habitat fragmentation within its extremely limited range in the Atlantic Forest of Brazil. Agricultural expansion, particularly cattle ranching and crop cultivation, continues to reduce the remaining forest patches where this endemic species occurs. Urban development pressures and infrastructure projects further fragment the already restricted habitat, isolating small populations and reducing genetic diversity.
Where does Calycorectes wurdackii live?
Calycorectes wurdackii occurs in Peru. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Calycorectes wurdackii?
The main threats to Calycorectes wurdackii are 3.2, 5.3, ai-1, and ai-2. The full IUCN-classified threat record for this species is detailed on the species page.
