Abstract :This study based on the vegetation field survey between April 1993 and October 1997 is done for the purpose of determining the vegetation of Deveci Mountains insert ignore into journalissuearticles values(Yozgat-Tokat);. During the plant vegetation seasons, 1400 plant samples were collected from the research area. 456 taxa and 262 genera to be belonging to 63 families were determined. In the survey area, five different vegetation types coniferous and deciduous forest, scrub, steppe, rocky and wet grassland were present. The threat categories of the endemic species of Deveci Mountains were determined and evaluated according to ‘Red Data Book of Turkish Plants’, which was prepared by using IUCN criteria. A total of 65 plant taxa were determined as endemic insert ignore into journalissuearticles values(14.25% of all taxa);. Highest ratios of endemic taxa were from families Fabaceae insert ignore into journalissuearticles values(16.92%); and Lamiaceae insert ignore into journalissuearticles values(16.92%);. Phytogeographic regions insert ignore into journalissuearticles values(Chorotypes); among endemic taxa were listed as Irano-Turanian 35 insert ignore into journalissuearticles values(53.85%);, Eastern Mediterranean 3 insert ignore into journalissuearticles values(4.62%);, Euxine 2 insert ignore into journalissuearticles values(3.08%);, Euro-Siberian 1 insert ignore into journalissuearticles values(1.54%);, while phytogeographic origin of insert ignore into journalissuearticles values(24 taxa); 36.92% of endemic taxa were Unknown. As endemic taxa and their threat categories are evaluated, 1 insert ignore into journalissuearticles values(1.54%); species was found to in Endangered, 4 insert ignore into journalissuearticles values(6.15%); in Vulnerable, 7 insert ignore into journalissuearticles values(10.77%); in Near Threatened and 53 insert ignore into journalissuearticles values(81.54%); in Least Concern according to IUCN criteria. When the plant taxa were classified and analysed according to Raunkiaer’s life forms, Hemicryptophytes were determined to be the most common plant taxa insert ignore into journalissuearticles values(76.92%);, Chamaephytes come next insert ignore into journalissuearticles values(9.23%);, is followed by the Therophytes insert ignore into journalissuearticles values(7.69%);, and then come Phanerophytes insert ignore into journalissuearticles values(4.62%);. While Geophytes have the least number of plant taxa with 1 species insert ignore into journalissuearticles values(1.54%);.
