Floristic diversity of floodplain oaks of the Yanuartsev forestry Department of the West Kazakhstan region

Abstract

The article considers the diversity of the flora of floodplain oak forests in the middle reaches of the Ural   river in the forestry of Yanuartsevo. The area of oak forests in the forest area is 1037 ha. Zhe object of research was oak   and oak associations. According to traditional methods (A.N.Shennikov, B.A.Bykov, A.I.Tolmachev, A.Z.Petrenko) oak-sedge,   oak-blackberry, oak-kirkazon, oak-lily of the valley, oak-grass associations were studied. A.Z.Petrenko (1964), P.G. Pugachev   (1967), F.H.Gimadieva (2002), T.E.Darbayeva, M.V.Mamysheva (2014) studied floodplain oak forests. From 2018 to 2019, oak   associations of 72 plant species were studied, grouped into 30 families and 61 genera. The results of biomorphological analysis   showed that perennial monocarpic plants predominate (67%), while tree species make up (25%). Ecological analysis showed that   mesophytes (68%) and mesoxerophytes (17%) predominate. Analysis of phytocenosis showed that forest (35%) and meadow   (29%) species predominate, while steppe (19.4%) species have a small share. Geographical analysis showed that Holarctic (57%)   and European (24%) species predominate in oak associations. Because our region is close to the Holarctic Kingdom. Yanuartsev   forestry is located on the territory of the Kirsanov state Zoological reserve, so medicinal (25%) species predominate, followed   by forage (21%) and ornamental species (17%). The reserve regime has a positive impact on the existence of these species.
