Abstract:
Eriolobus trilobatus (Poir.) M. Roem. is a rare and endangered forest tree species which has ecological and economic significance. The species has traditionally been used for food, medicinal and ornamental purposes and it also provides food and habitat for wildlife in its natural ecosystems. This study comprehensively assesses the distribution, local uses, population status, and threats of E. trilobatus across Türkiye. Additionally, it examines the species’ conservation, the transmission of local knowledge and generational differences in its use. To this end, the study employs the combination of site surveys and structured interviews. Site surveys were carried out across nine provinces covering the entire distribution range in Türkiye. Besides, online structured interviews were performed with 36 participants including local residents and forestry staff. Then, the collected data were analysed using SPSS software. 33 out of 36 participants recognized E. trilobatus mainly based on its fruit and morphological characteristics. Fruits were the main part of the plant used mostly for food while leaves, flowers and wood were rarely utilized. E. trilobatus is highly recognized in Turkish culture but it is vulnerable to region-specific anthropogenic pressures (such as mining, grazing and agricultural expansion), taxonomic confusion, population aging, limited natural regeneration and habitat degradation. Age-related differences in species knowledge and use were evident, with older generations showing higher recognition and utilization. This emphasizes the importance of family-based knowledge transmission for conservation. Effective conservation necessitates integrated strategies that combine in situ protection, ex situ propagation, community engagement and sustainable use practices.
