The investigation of stands of Quercus robur L. an early-flowering forms and a late-flowering forms in the Donetsk region was performed. The analysis of the phenology rhythm of the two forms pedunculate oaks of the investigation for three years by eleven basic calendar phases of phenology allows you to clearly separate them phenospectrum. The distribution map of an early-flowering forms and a late-flowering forms of Q. robur in the Donetsk region was designed. Also, according to the research, succeeded in isolating the complex phenological form, which is a fact of evolutionary synthesis of an early-flowering forms and a late-flowering forms. It is revealed the association of an early-flowering form Q. robur to lowland landforms, and a late-flowering form to taller landforms. It is permitting to conclude, that pedunculate oak restoration should be carried out taking into account the phonological forms information, dedicated to different types of landscapes.
