Abstract
This study aims to determine the threat categories of endemic plants in the vegetation of Sakarat Mountain (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 (decidious, mixed coniferous and deciduous), subalpine, steppe, rocky, wet grassland and segetal were determined. 40 plant taxa (8.09% of all taxa) were confirmed as endemic. The families with the highest rate of endemic taxa are Fabaceae (15%) and Lamiaceae (15%). Phytogeographic regions (Chorotypes) among endemic taxa were listed as Irano-Turanian 13 (32.5%), Euro-Siberian 9 (22.5%), Mediterranean 1 (2.5%), while phytogeographic origin of (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 (2.5%) is in Endangered, 3 species (7.5%) in Near Threatened and 36 species (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%.
