Cnidoscolus hamosus

Declining

Overview

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

Cnidoscolus hamosus faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development across its limited range. The species' restricted distribution makes it particularly vulnerable to localized threats, with remaining populations fragmented and isolated. Mining activities and infrastructure development have further reduced available habitat, while the plant's specific soil and microclimate requirements limit its ability to colonize new areas.

Threat summary

Habitat

This species inhabits dry tropical forests and scrublands, typically growing in well-drained soils on rocky slopes and hillsides. It requires specific microclimate conditions with seasonal rainfall patterns and is adapted to nutrient-poor, calcareous substrates.

Frequently asked questions

Why is Cnidoscolus hamosus classified as Critically Endangered?
Cnidoscolus hamosus 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. Cnidoscolus hamosus faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development across its limited range. The species' restricted distribution makes it particularly vulnerable to localized threats, with remaining populations fragmented and isolated. Mining activities and infrastructure development have further reduced available habitat, while the plant's specific soil and microclimate requirements limit its ability to colonize new areas.
Where does Cnidoscolus hamosus live?
Cnidoscolus hamosus occurs in Brazil. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Cnidoscolus hamosus?
The main threats to Cnidoscolus hamosus 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.
