Abstract: This paper develops a method of parameter estimation for some differential dynamic systems in ecology. This method combines simplex method for optimizing a function with Gill-method of numeric solution of a differential equation, The results of parameter estimation of Logistic and Cui-Lawson equations shows a good adaptation of this method.

Key words: Cui-Lawson equation, Logistic equations, Simplex method, Parameter estimation
