<p>The ethnobotanical field study was conducted among the residents of 25 villages located on the Rujan Mountain in Serbia (130 informants), a multicultural border area inhabited by Serbs and Albanians. The questionnaire included general demographic information about the respondents, as well as specific questions regarding the use of wild food plants. In total, 2011 use reports on various plant resources were documented. The analysis of the collected data involved calculating the informant consensus factor, conducting comparisons based on ethnicity and gender of the most frequently reported wild food plants, and performing a multivariate correspondence analysis. The comparison with published data from neighboring Balkan regions using the Jaccard index was performed.</p><p>A total of 35 wild food plants, representing 20 different families, were identified in the survey. The most frequently mentioned families were Rosaceae, Urticaceae, and Polygonaceae. <i>Urtica dioica</i>, <i>Rubus caesius</i>, and <i>Cornus mas</i> were the most reported species. Wild food plant species on Rujan Mt were consumed fresh, cooked, or processed into a variety of products. Among the 11 distinct forms of consumption, raw fruits (566 use reports [URs]), vegetables for cooking (399 URs), and syrup (391 URs) were the most frequently reported. A total of 1127 use reports were related to fruits, while 515 use reports concerned the leaves, the second most consumed plant parts.</p><p>This study could contribute to the diversification of strategies in the food industry by providing valuable insights into the use of wild plants.</p>
