The purpose of this study is to measure proportionally the productivity of partial and total factors in state forest enterprises. As for partial productivity, land, capital and employee productivity measures are considered. The data envelopment analysis, which is a non parametric method has been used in the study. For the enveloping model, the BBC (Banker, Charnes, Cooper) models have been preferred as input-oriented. The Mediterranean Region of Turkey at thirty-seven state forest enterprises made up the study area. The productivity scores have been evaluated in accordance with 8 input and 4 output factors. According to the results of the study: land productivity had 7 enterprises, employee productivity had 9, capital productivity had 10 and the total productivity had 19 enterprises assesses to be productive. The lowest efficiency scores were evaluated to be on the employee productivity with an average value of 0.698. The inefficiency of the total productivity was thought to be due to the amount of workers and thus the amount of fees paid in big amounts. The following reason is assessed to be due to the total size of land bound to the enterprises.
