The data of estimating the number of Ixodes perculcatus by two methods (the number of ticks per flag-hour and that per flag-kilometer) in the near-Baikal area were analyzed. According to these values, the abundance of taiga ticks in individual calculations ranged from 0 to 394. The association between the time of passage and the number of collected ticks was positive and high significant. The correction factors were calculated to obtain the abundance values expressed in per flag-kilometer units from the abundance values per flag-hour and conversely. The value of these factors depended on the number of ticks.
