The mixture distibution was proposed as a mathematical model to describe the height frequency distributions of broadleaves stands. In order to estimate the parameters of the mixture distribution, two methods are useful, one is the method of moments estimation and the other is the least squares procedure for resolving overlapped peaks. The model, the two-component univariate lognormal mixture distribution, was applied to a observed height frequency distribution of a broadleaved stand in Shimane Prefecture. The model achieved a good fit to the observed distribution and it may be useful for analyzing the height frequency distributions of broadleaved stands.
