Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

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.
