Abstract
In this study, preliminary growths of natural sessile oak (Quercus petraea (Mattuschka) Lieb.) seedlings whichwere made Uniform Shelterwood Method were determined in the sessile oak natural regeneration application in42 forest division in İstanbul-Bentler Forest Range District. Furthermore, number of sessile oak seedlings, heightgrowths and root collar diameters of seedlings were investigated in the 10 experimental areas which were takenin the regeneration area which was 2.0 hectares for 4 years (2007-2010). According to the results of count andmeasurements in 2007, it was determined that number of sessile oak seedlings ranged from 56 to 123 per m2,mean height growth from 2.7 cm to 4.6 cm and mean root collar diameter from 6.5 mm to 8.2 mm weredetermined. According to the results of count and measurements in 2008, it was determined that number ofsessile oak seedlings ranged from 43 to 106 per m2, mean height growth from 4.8 cm to 6.5 cm and mean rootcollar diameter from 7.3 mm to 10.6 mm were determined. According to the findings which were obtained fromcount and measurements in 2009, it was determined that number of sessile oak seedlings ranged from 30 to 92per m2, mean height growth from 8.6 cm to 9.8 cm and mean root collar diameter from 8.4 mm to 11.5 mm weredetermined. According to the last count and measurements in 2010, it was determined that number of sessile oakseedlings ranged from 18 to 82 per m2, mean height growth from 9.2 cm to 12.3 cm and mean root collardiameter from 10.2 mm to 12.4 mm were determined.
