The study was performed in Ankara Province, Central Anatolia (39°56′N, 32°52′E). This province covers a total surface area of 25,938 km 2 . In the central and southern parts of the province, the climate is continental, with steppetype vegetation. However, in the northern part of the region, the climate changes to a more humid and wet Black Sea climate, and vegetation changes to forests (generally rare oak forests). Altitude varies between 900 and 2015 m above sea level, and mean annual temperature is 14.4 °C Abstract: A systematic study has been carried out on hard ticks from Ankara Province, Turkey. Between April 2010 and July 2012, 1800 tick specimens belonging to 9 species were identified at 31 locations in 9 districts. Tick species are listed as follows: Rhipicephalus sanguineus group (43.44%), Rhipicephalus bursa (36.67%), Hyalomma marginatum (8.83%), Haemaphysalis parva (6%), Hyalomma aegyptium (2.39%), Hyalomma excavatum (1.33%), Dermacentor marginatus (1.06%), Haemaphysalis punctata (0.22%), and Hyalomma detritum (0.06%). Ticks were collected from host animals and from vegetation via the flagging method. The species of the genus Rhipicephalus were present in most of the study areas, the most common being the Rhipicephalus sanguineus group (20/31). Hyalomma species were mostly collected from host animals, with Hyalomma marginatum being the most common species in this genus (8.83%). We also observed seasonal variations in abundance, with the highest number in May. The district with the most abundant ticks was determined to be Kızılcahamam, which had the highest tick abundance rate of 28.6%.
