Scots pine (Pinus sylvestris L.) sapwood and heartwood stakes treated with CCA-C and creosote were tested for one- year in a field plot in Bartın region in Turkey. Scots pine heartwood stakes had lower preservative retention than sapwood stakes. Bending strength of the stakes was decreased after impregnation and one-year field test. While the bending strength of untreated sapwood was 93.79 N/mm2 , it was decreased to 41 N/mm2 after field test. Mean soundness index of heartwood stakes was better than sapwood stakes. White rot decay was observed in untreated stakes, especially in sapwood stakes.
