Matelea tigrina

Unknown

Overview

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

Matelea tigrina faces severe threats from agricultural expansion and urban development across its limited range in southeastern Brazil. The species' specialized habitat requirements make it particularly vulnerable to fragmentation, as remaining populations become isolated in small forest patches. Invasive plant species further degrade the quality of remaining habitat, while climate change may alter the specific microclimatic conditions this endemic vine requires for survival.

Threat summary

Habitat

This endemic Brazilian vine inhabits remnant Atlantic Forest fragments and forest edges in southeastern Brazil, typically growing in humid, shaded understory environments. The species requires specific soil conditions and microclimatic stability found in mature forest ecosystems.
