Monotagma rudanii

Unknown

Overview

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

Monotagma rudanii faces severe pressure from deforestation and agricultural expansion throughout its limited range in the Atlantic Forest of Brazil. The species' specialized habitat requirements make it particularly vulnerable to forest fragmentation, as it depends on the understory microclimate of intact rainforest. Mining activities and urban development have further reduced available habitat, while climate change threatens to alter the humid conditions essential for this plant's survival.

Threat summary

Monotagma rudanii is endemic to the understory of Atlantic Forest rainforest in southeastern Brazil, where it grows in humid, shaded conditions with rich organic soils. The species requires the stable microclimate provided by intact forest canopy and is typically found at elevations between 200-800 meters.
