Erisma arietinum

Declining

Overview

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

Erisma arietinum faces severe population decline primarily due to extensive deforestation and habitat conversion throughout its Amazon basin range. Logging operations specifically target this valuable timber species for its high-quality wood, leading to direct exploitation pressure. Agricultural expansion and cattle ranching have fragmented remaining forest patches, isolating populations and reducing genetic diversity. Climate change compounds these pressures by altering precipitation patterns critical for this moisture-dependent species.

Threat summary

Habitat

Erisma arietinum inhabits primary and secondary tropical rainforests of the Amazon basin, typically occurring in well-drained terra firme forests at elevations up to 800 meters. The species requires high humidity levels and consistent rainfall, thriving in the understory and canopy layers of mature forest ecosystems.

Frequently asked questions

Why is Erisma arietinum classified as Critically Endangered?
Erisma arietinum 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. Erisma arietinum faces severe population decline primarily due to extensive deforestation and habitat conversion throughout its Amazon basin range. Logging operations specifically target this valuable timber species for its high-quality wood, leading to direct exploitation pressure. Agricultural expansion and cattle ranching have fragmented remaining forest patches, isolating populations and reducing genetic diversity. Climate change compounds these pressures by altering precipitation patterns critical for this moisture-dependent species.
Where does Erisma arietinum live?
Erisma arietinum occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Erisma arietinum?
The main threats to Erisma arietinum 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.
