In Poland, the demand and availability of high efficiency machines such as harvesters and forwarders has been increasing in the last decade. On the one hand, forestry needs technologies safe for the environment, soil, water, and people. On the other hand, Polish forestry investors and service companies are constantly buying both new and second-hand harvesters and forwarders. The main aim of this paper was to determine the actual number of machines currently used in Poland. The secondary objective was to describe the ownership structure of these machines. Information on the number of forest machines is very important for economic reasons. The Key Performance Indicator (KPI) informs us “where we are” and what tendency and trends we may expect. The number of forest machines needs to be monitored on a regular basis.
