Abstract :This study aims to determine the threat categories of endemic plants in the vegetation of Sakarat Mountain insert ignore into journalissuearticles values(Amasya); on the basis of the vegetation field survey in 2004 and 2005 years. Plant samples were collected in their vegetation seasons. According to results, 78 families, 283 genera and 494 taxa are identified. As a result of field surveys, six different vegetation types forest insert ignore into journalissuearticles values(decidious, mixed coniferous and deciduous);, subalpine, steppe, rocky, wet  grassland and segetal were determined. 40 plant taxa insert ignore into journalissuearticles values(8.09% of all taxa); were confirmed as endemic. The families with the highest rate of endemic taxa are Fabaceae insert ignore into journalissuearticles values(15%);  and Lamiaceae insert ignore into journalissuearticles values(15%);. Phytogeographic regions insert ignore into journalissuearticles values(Chorotypes); among endemic taxa were listed as Irano-Turanian 13 insert ignore into journalissuearticles values(32.5%);, Euro-Siberian 9 insert ignore into journalissuearticles values(22.5%);, Mediterranean 1 insert ignore into journalissuearticles values(2.5%);, while phytogeographic origin of insert ignore into journalissuearticles values(17 taxa); 42.5% of endemic taxa were Unknown. The threat categories regarding the endemic species were determined and analysed according to “Red Data Book of Turkish Plants” adopted 2001 IUCN criteria. In the evaluation phase of the endemic taxa and their threat categories, it was found that 1 species insert ignore into journalissuearticles values(2.5%); is in Endangered, 3 species insert ignore into journalissuearticles values(7.5%); in Near Threatened and 36 species insert ignore into journalissuearticles values(90%); in Least Concern according to the criteria of 2001 IUCN. When the life forms of plant taxa were analysed, it was determined that Hemicryptophytes have the most number of plant taxa with 82.5%, Therophytes and Geophytes have the less than others 2.5%.
