Elaphoglossum stigmatolepis, a fern species endemic to the semi-evergreen or evergreen forests of the Western Ghats of India, has recently garnered attention due to its precarious status within its native habitat. Thriving within the unique microclimates of these regions, this fern has been assessed for the first time. The results of this assessment are concerning, as the species has been classified as Endangered under the IUCN Red List Categories and Criteria 3.1. The limited population of E. stigmatolepis underscores its vulnerability, highlighting the pressing need for dedicated conservation efforts. This assessment represents a pivotal step in acknowledging and addressing the threats faced by E. stigmatolepis, emphasizing the urgency of implementing measures to ensure its survival and safeguarding the biodiversity of the Western Ghats.
