Pteris pseudolonchitis

Unknown

Overview

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

Pteris pseudolonchitis faces severe population decline due to habitat destruction from urban development and agricultural expansion in its limited range. The species is particularly vulnerable to forest fragmentation, which disrupts the humid microclimate conditions essential for its survival. Collection pressure for horticultural trade has further reduced wild populations, while invasive plant species compete for suitable growing sites.

Threat summary

Habitat

This fern species inhabits humid, shaded forest understories and rocky crevices in montane regions, typically growing on limestone substrates or volcanic soils. It requires consistent moisture levels and protection from direct sunlight, making it highly dependent on intact forest canopy cover.

Frequently asked questions

Why is Pteris pseudolonchitis classified as Critically Endangered?
Pteris pseudolonchitis 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. Pteris pseudolonchitis faces severe population decline due to habitat destruction from urban development and agricultural expansion in its limited range. The species is particularly vulnerable to forest fragmentation, which disrupts the humid microclimate conditions essential for its survival. Collection pressure for horticultural trade has further reduced wild populations, while invasive plant species compete for suitable growing sites.
Where does Pteris pseudolonchitis live?
Pteris pseudolonchitis occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
