An intensive removal of small mammals in three forest biotopes in the Bialowieża National Park has been carried out. The Standard-Minimum (SM) method (Grodziński, Pucek and Ryszkowski 1966) has been applied. Additionally coniform traps were set up at the points of trapping with the purpose of removing Insectivore. Total 1,522 individuals of small mammals were captured. The SM method not always enables to estimate the number of lnsectivora according to the method of linear regression. It has been shown that Rodentia from the first day of removal come intensively to the area where the removal is carried out. Differences in the captures on the external strip and in the centre are significant for Rodentia and this may cause an overestimation of the number when catches from the whole area are considered. The density per one hectare should be calculated, according to this method, only for the central part. The period of removal can be shortened from seven to four-five days.
