The paper presents data on acquisition of conifer cones from 16 seed extraction plants operating on the territory of Poland during four consecutive years from 2009 to 2012. A high variability was observed in provision of seed units to the seed exaction plants related to specificity of a given seed year. During the four analyzed years the most commonly acquired cone was that of Scots pine – above 1.3 thousand Mg, and the most rare were pines of common fir – 31 Mg. The plants that process the largest number of cones are seed extraction plants in forest districts of Jarocin, Kluczbork and Rytel where over 600 Mg of cones were extracted. Conifer cones, which are usually treated as waste, may be utilized as an energy source. After seed extraction their mass decreases from 16 to 30% depending on the species. The analysis showed that the annual quantity of conifer cones that can be used as an energy source is on average 270 Mg of empty cones.
