Paesia glandulosa

Unknown

Overview

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

Paesia glandulosa faces severe threats from habitat destruction due to agricultural expansion and urban development across its limited range. The species' restricted distribution makes it particularly vulnerable to localized disturbances, while invasive plant species compete for resources in its native forest understory habitats. Climate change poses additional pressure through altered precipitation patterns that affect the moist conditions this fern requires for reproduction and growth.

Threat summary

Habitat

Paesia glandulosa inhabits moist forest understories and shaded rocky areas, typically growing in well-drained soils with consistent moisture levels. The species is found in temperate forest ecosystems where it forms part of the native fern flora in protected microsites.
