Thelypteris grantii

Declining

Overview

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

Thelypteris grantii faces severe pressure from habitat destruction as its native forest ecosystems are cleared for agricultural expansion and urban development. The species' limited distribution makes it particularly vulnerable to localized threats, with small population fragments increasingly isolated from one another. Climate change poses an additional threat through altered precipitation patterns and temperature shifts that may exceed the species' adaptive capacity.

Threat summary

Habitat

This endangered fern species inhabits moist, shaded understory environments within tropical and subtropical forests. It typically grows in areas with high humidity and consistent moisture levels, often along stream banks or in forest valleys where soil conditions remain favorable year-round.

Why is Thelypteris grantii classified as Endangered?
Thelypteris grantii 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. Thelypteris grantii faces severe pressure from habitat destruction as its native forest ecosystems are cleared for agricultural expansion and urban development. The species' limited distribution makes it particularly vulnerable to localized threats, with small population fragments increasingly isolated from one another. Climate change poses an additional threat through altered precipitation patterns and temperature shifts that may exceed the species' adaptive capacity.
Where does Thelypteris grantii live?
Thelypteris grantii occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
