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

Abstract The consequences of a catastrophic windthrow in a old-growth hemiboreal stands of the Kologrivsky Forest Reserve were investigated. The degree of damage to tree stands was assessed by interpretation of the Sentinel-2 satellite images. Data from the GBIF portal, SRTM global terrain height models, and tree stand heights were used for the quantitative analysis of factors affecting the presence of wind damage. It was found that tree stands on an area of 277.9 hectares (40.5% of the entire massif) were damaged by windthrow. The results of the analysis of height models and regression models showed that spruce stands are more vulnerable to wind damage, as well as stands of greater height or those growing at higher elevation on the ground.
