MONITORING RESULTS OF THE MONGOLIAN OAK YIELD AS A FORAGE BASE FOR UNGULATES IN THE BASTAK NATURE RESERVE

The Mongolian oak Quercus mongolica Fisch. ex Ledeb. along with the Korean pine, Pinus koraiensis Siebold et Zuss form ecosystem integrity basis at Bastak Reserve. study of these species productivity is important and relevant. Currently, a number articles have been published on pine nut in protected area. However, information concerning yield available only Annals Nature. This paper presents assessment data acorns as fodder base for wild animals being nutrition Amur tiger. monitoring has carried out Nature Reserve since 2015. first acorn harvest was obtained 2017. made permanent transects different areas reserve. research shows that reserve irregularly. productive lean years alternation trend not determined yet, unlike Lazovsky Perhaps, because short period. significantly influenced by weather conditions, primarily, absence rainy days during flowering It noted there good nuts partially compensating ungulates. maintaining stable density ungulates needs certain bio-technical measures, such feeding grounds.
