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.
It has been established that with the improvement of climatic conditions in the high mountains of the Southern Urals, an upward shift of the upper forest boundary along the altitudinal gradient is observed. The process of forest regeneration in this area is highly prolonged over time. Cyclically uneven-aged and stepwise uneven-aged stands are forming, consisting of several morphologically indistinct forest generations.
