In this study I analysed how burning affects sprouting ability and survival of oak (Quercus robur) during the first season after a burn in southern Sweden. The study consisted of two separate field tests; in the first, two 300 m2- plots in western oak dominated forest were burned to analyze the fire behavior and the immediate mortality of oak and beech seedlings defined as individuals (> 20cm of height). At the end of the season almost 50% of the oak seedlings had resprouted while the beech seedlings had 100% mortality. An attempt to investigate the effect of the burn of artificially sown acorns was totally ruined by wild boar grouting before any conclusive results could be seen. In the second test the resprouting ability of oaks of varying diameters (average BHD 7-9 cm, range 2-42 cm) was examined one season after a prescribed burn in southeastern Sweden. The burn was considered to be of medium to high intensity, with flame lengths varying between 0,2-4 m. The mortality of main stems of oak caused by the fire was 96 %. 58 % of the stems had new sprouts be the time of the survey. Stems with diameter of 17 20 cm bhd suffered 100 % mortality and only 20 % had resprouted.
