Statistical parameters describing sets of eccentricity index values calculated for sample populations of trees affected by landsliding (Suchawa study site), prevailing wind (Hubertka study site) and for sample populations of reference trees growing in sites unaffected by landsliding and prevailing wind (Suchawa reference site, Hubertka reference site)_ Upslope/windward (up_/wind_) and downslope/leeward (down_/lee_) eccentricity was separated in the calculations_
