Asplenium dissectum

Unknown

Overview

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

Asplenium dissectum faces severe threats from habitat destruction due to urban development and agricultural expansion in its limited range. The species' extremely restricted distribution makes it particularly vulnerable to localized disturbances, while invasive plant species compete for the specialized rocky habitats it requires. Climate change poses additional risks through altered precipitation patterns that could affect the moisture-dependent microhabitats essential for this fern's survival.

Threat summary

Habitat

This critically endangered fern inhabits rocky crevices, cliff faces, and stone walls in coastal and montane environments. It requires well-drained, alkaline substrates with consistent moisture levels and partial shade protection.

Frequently asked questions

Why is Asplenium dissectum classified as Critically Endangered?
Asplenium dissectum is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Asplenium dissectum faces severe threats from habitat destruction due to urban development and agricultural expansion in its limited range. The species' extremely restricted distribution makes it particularly vulnerable to localized disturbances, while invasive plant species compete for the specialized rocky habitats it requires. Climate change poses additional risks through altered precipitation patterns that could affect the moisture-dependent microhabitats essential for this fern's survival.
Where does Asplenium dissectum live?
Asplenium dissectum occurs in Argentina, Brazil, Colombia, Costa Rica, Cuba, and Dominican Republic (plus 14 other countries). Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Asplenium dissectum?
The main threats to Asplenium dissectum are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
