Abstract


Gradation of heights and class of thickness of red oak and English oak for 11-year-old mixed crops in the dry oak forests is given. Average heights and diameters for each species is calculated by standard methods. Both species have the same trend of trunks distribution on the class of thickness. It is found that plantations of red oak are more productive in the studied conditions. The English oak on dry oak forests has shown itself as less productive and more slow-growing than red oak.

Keywords
