Senaea janeirensis

Declining

Overview

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

Senaea janeirensis faces severe threats from rapid urban expansion and infrastructure development in the Rio de Janeiro metropolitan area, which has fragmented and destroyed much of its Atlantic Forest habitat. The species is particularly vulnerable due to its extremely restricted range and small population size, making it susceptible to local extinctions from even minor habitat disturbances. Pollution from urban runoff and invasive plant species further degrade the remaining forest fragments where this endemic species persists.

Threat summary

Habitat

This species is endemic to the Atlantic Forest remnants in the Rio de Janeiro region of Brazil, typically found in humid montane forest environments.
