The aim of the study reveals the importance of lichen richness within non-protected and protected areas, especially lichen species included in National Red List. This study was performed within protected and non-protected areas from Romania situated at both high and low altitude. The studied group is represented by lichens with a great diversity of their species. The data were collected between 2020-2023 from different geomorphological units of Romania. In total 94 lichen species were found of which 34 within non-protected areas and 86 within protected areas. Statistical analysis indicated non-significant results as regard the differences betwen the total number of lichen species and the number of lichens included in National Red List among non-protected and protected areas. Also, non-significant results were obtained as regard the differences between data recorded among non-protected and protected areas. The main conclusion is represented by a high number of lichen species identified within protected areas compared to non-protected areas. Keywords: lichens, National Red List, protected areas, Romania.
