• A graphic method for quickly estimating an animal population density and the precision of the estimate in field survey is proposed in this paper. The properties of this method are as follows : (1) The density estimation is made only from the frequency of sampling usits having zero individuals and one individual assuming a negative binomial or Poisson distribution as the spatial pattern of the animal; (2) No preliminary survey before the main survey is required; (3) Estimates of the population density and the precision of these estimates are obtained in the field; (4) If required, one can improve the precision by taking more additioanl sampling units immediately in the field; (5) Much time and effort in counting individuals and estimating their density may be saved by using this method.
