Sciodaphyllum ayangannense

Unknown

Overview

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

Sciodaphyllum ayangannense faces severe threats from deforestation and habitat fragmentation in the Guiana Highlands, where mining activities and agricultural expansion continue to reduce its extremely limited range. The species' restriction to specific elevational zones and unique geological formations makes it particularly vulnerable to any habitat disturbance. Climate change poses an additional threat by potentially altering the montane conditions this endemic species requires for survival.

Threat summary

Habitat

This species is endemic to the montane forests and tepui formations of the Guiana Highlands, occurring at specific elevations where unique geological and climatic conditions create specialized microhabitats. It typically grows in cloud forest environments with high humidity and consistent moisture levels characteristic of these ancient mountain formations.
