Adiantum sericeum

Unknown

Overview

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

Adiantum sericeum faces severe pressure from habitat destruction as its specialized limestone cliff environments are increasingly disturbed by quarrying activities and infrastructure development. The species' extremely limited distribution makes it particularly vulnerable to localized threats, with small population fragments at risk of complete elimination from individual sites. Climate change poses an additional threat through altered precipitation patterns that could affect the delicate moisture balance required in its rocky habitat niches.

Threat summary

Habitat

This endemic fern species inhabits specialized limestone cliff faces and rocky crevices in tropical montane regions, typically growing in shaded, moisture-rich microhabitats where it can establish in thin soil deposits. The species requires specific geological conditions and is restricted to calcareous substrates at elevations where humidity levels remain consistently high.

Frequently asked questions

Why is Adiantum sericeum classified as Endangered?
Adiantum sericeum is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Adiantum sericeum faces severe pressure from habitat destruction as its specialized limestone cliff environments are increasingly disturbed by quarrying activities and infrastructure development. The species' extremely limited distribution makes it particularly vulnerable to localized threats, with small population fragments at risk of complete elimination from individual sites. Climate change poses an additional threat through altered precipitation patterns that could affect the delicate moisture balance required in its rocky habitat niches.
Where does Adiantum sericeum live?
