This crossing includes the floristic characteristics of the passage generation area and the vascular plant species. The aim is to identify the biodiversity of our country, recognize, preserve plants and contribute to all work related to plants. The area of research covers the arrow and its surroundings and is located within the A2, A3, B2 and B3 squares according to Davis’s square system. The research area begins from about 280 meters and reaches 1300 meters high. From the study area, 3650 plant samples were collected in 2016-2019. Collected plant samples are pressed and dried according to herbaryum techniques. The florist list is organized on the basis of the APG III system. As a result of the evaluation of the materials collected, 552 species of 109 families, 1396 species and subterranean taxons were confirmed. The largest family is Asteraceae (148 species), the second Fabaceae (132 species). The largest species are Astragalus L. with 23 species and Trifolium L. with 20. According to the IUCN categories, 65 plant taxons are at risk. 50 of the taxons under risk are LC, 8 NT, 5 VU, 1 CD and 1 CR. The distribution of plant taxons in the field of research is as follows: 9.02 percent are Iran-Turan, 6.94 percent Mediterranean and 11.1 percent are European-Siberian elements. The percentage of unknown in the multi-regional or phytocographic area is 65.96%. 90 of these taxons are endemic and the endemic rate in the region is 6.44%.

This study includes the floristic features of the Passage zone and vascular plant species. It is aimed to determine the biodiversity of our country, to recognize and protect the plants and to contribute to all studies related to plants. The research area covers Bilecik and its surroundings and is in A2, A3, B2 and B3 squares according to Davis's grid system. The research area starts from about 280 m and reaches up to 1300 m elevation. 3650 plant samples were collected from the study area in 2016-2019. Collected plant samples were pressed and dried in accordance with herbarium techniques. The floristic list is based on the APG III system. As a result of evaluating the collected materials, 552 genera, 1396 species and subspecies taxa belonging to 109 families were determined. The largest family is Asteraceae (148 species), the second is Fabaceae (132 species). The largest genera are Astragalus L. with 23 species and Trifolium L. with 20 species. According to the IUCN categories, 65 plant taxa are at risk. 50 of the taxa at risk are in LC, 8 in NT, 5 in VU, 1 in CD and 1 in CR. The distribution of plant taxa to the phytogeographic regions is as follows; 9.02% Iran-Turan, 6.94% Mediterranean and 11.1% European-Siberian elements. The rate of those who are not multi-region or whose phytogeographic region is unknown is 65.96%. 90 of these taxa are endemic and the rate of endemism in the region is 6.44%.
