The main reason for degradation of oak forests in the Middle Danube Plain (Bulgaria) are: The restriction of oak forests area by uprooting the trees for extending the agricultural lands; The reconstruction of oak forests with hybrid black poplars, Robinia pseudoacacia and Pinus nigra; The regressive succession trends. As result of improper management the oak forest are replaced by other tree and shrub species. Parallel with the regressive successions trends of returning of oaks on deserted agricultural lands are observed. Pioneer species such as Rosa canina, Crataegus monogyna, Pyrus communis create conditions for indigenous oak species (Quercus cerris, Q. frainetto, Q. robur, Q pubescens, Q. petraea) to turn back.
