In this study, the floristic composition and EUNIS habitat types of Kale Höyük and its surroundings in Kırşehir Center were investigated. During the research, a total of 93 taxa, 4 of which are endemic, were detected naturally in our country. Families with the most taxa; Asteraceae (14 taxa), Poaceae (14 taxa), Brassicaceae (7 taxa) and Fabaceae (7 taxa) were determined. According to their phytogeographic distribution, taxa containing the most Iran Turan element (15 taxa) were determined. When evaluated according to IUCN threaten categories on a global scale, 27 taxa are in LC and 1 taxon are in DD category. 65 taxa do not have a threaten category (NE). Four endemic taxa were identified in the area, all of which were evaluated in the LC category (Achillea aleppica subsp. zederbaueri, Asperula stricta subsp. latibracteata, Crocus ancyrensis, Cyanus pichleri, Delphinium venulosum). It has also been observed that 35 taxa that are not naturally distributed in the area are evaluated as ornamental plants in parks and gardens. When the origins of these species were examined, it was determined that most of them originated in America, China and Europe. When the study area is examined according to EUNIS Habitat types; Grasslands and lands dominated by forbs, mosses or lichens (E1.3, E2.6), woodland, Woodland, forest and other wooded land (G5.4), Regularly or recently cultivated agricultural, horticultural and domestic habitats (I1.1, I1.5, I2.2) and Constructed, industrial and other artificial habitats (J1.1, J1.2, J4.2) has been determined that 4 different main habitat types, namely areas) are found in Kalehöyük and its surroundings.
