Table I
Differences between two juniper stands located on a south-facing (AS) and a north-facing slope (AN) with respect to microsite characteristics recorded in a circle of 1 m around the transect point (TP) and characteristics of nearest adult juniper trees and saplings. Non-parametric Kolmogorov-Smirnov test for independent groups was applied.
