Manettia nebulosa

Unknown

Overview

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

Manettia nebulosa faces severe threats from ongoing deforestation and agricultural expansion within its extremely limited range in the Atlantic Forest of southeastern Brazil. The species' restriction to specific microhabitats within montane cloud forests makes it particularly vulnerable to climate change-induced shifts in precipitation patterns and temperature regimes. Mining activities and urban development pressure in the region further fragment the remaining suitable habitat patches.

Threat summary

Habitat

This species is endemic to montane cloud forests in the Atlantic Forest biome of southeastern Brazil, typically occurring at elevations between 800-1,500 meters. It inhabits the understory and forest edges of humid, mist-shrouded forests where it grows as a climbing vine among dense vegetation.

Frequently asked questions

Why is Manettia nebulosa classified as Critically Endangered?
Manettia nebulosa 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. Manettia nebulosa faces severe threats from ongoing deforestation and agricultural expansion within its extremely limited range in the Atlantic Forest of southeastern Brazil. The species' restriction to specific microhabitats within montane cloud forests makes it particularly vulnerable to climate change-induced shifts in precipitation patterns and temperature regimes. Mining activities and urban development pressure in the region further fragment the remaining suitable habitat patches.
Where does Manettia nebulosa live?
Manettia nebulosa 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 Manettia nebulosa?
The main threats to Manettia nebulosa 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.
