Abstract:

   The article focuses on the problem of renewal of basic forest-forming tree species of the Karadag Nature Reserve– downy oak (Quercus  pubescens Willd., 1796), durmast (sessile oak) (Quercus petraea Liebl., 1784) under the influence of the environment-forming activity of wild ungulate animals Artiodactyla (wild boar – (Sus scrofa ussuricus Linnaeus, 1758), European roe deer – Capreolus capreolus Linnaeus, 1758).

   The dynamics of the population of wild ungulates in the reserve from 1986 to 2018 is presented. The population of European roe deer in different years ranged from 34 to 750 individuals, with an optimal population of 91 individuals on the entire territory of the reserve. The population of wild boar for 32 years ranged from 5 to 101 individuals, with an optimal population of 10 individuals. The data on feeding with branch food and dendroactivity of roe deer is given.  The marking activity of roe deer males on tree-shrub species and digging activity of wild boar at forage extraction is considered.

    Characteristics of the main forest-forming species in the Karadag Nature Reserve are given: they are durmast and downy oak. Data on the condition of undergrowth in the plantations of oak and downy oak in the mountain forests of the Karadag Nature Reserve are given.  A comparative analysis of small, medium and large undergrowth in the sample areas laid in 2005-2006 and in 2017 for undergrowth damage monitoring was made.  A great destruction of the undergrowth was observed. The renewal of the durmast and downy oak has to be considered as unsatisfactory.

Keywords: oak-tree, European roe deer, wild boar, natural seed resumption under the influence of animals, Karadag Nature Reserve.
