Bryophytes play a crucial role in ecosystems by enhancing biodiversity, regulating water cycles, preventing soil erosion, and serving as bioindicators of environmental change. Despite their ecological significance, they face increasing threats from both natural and human-induced factors. This study aims to identify, evaluate, and prioritize the key drivers of bryophyte extinction using an interval-valued Fermatean fuzzy step-wise weight assessment ratio analysis (IVFF-SWARA) approach. Within the model, five main factors and twenty-five subfactors are defined. The opinions of different experts are gathered to obtain input data. IVFF-SWARA is applied to determine the weight of each factor. According to the modeling results, the top five most important factors are “deforestation and agricultural activities”, “habitat fragmentation and microhabitat loss”, “changes in precipitation patterns”, “temperature increase”, and “urbanization and infrastructure development”. The novelty of this study lies in framing bryophyte extinction assessment as a multicriteria decision-making problem, applying IVFF logic and the SWARA method to this domain, constructing a comprehensive hierarchical factor system, and thereby providing a systematic, uncertainty-aware analytical perspective that offers new insights to the existing literature. This study provides valuable guidance for decision-makers in identifying the most critical threats to bryophytes and offers key insights for implementing effective conservation measures and policy interventions.
