Table II
Differences between transect point (TP, absence of sapling) and sapling point (SP, presence of sapling) of two juniper habitats located on a south-facing (AS) and a north-facing slope (AN) with respect to microsite characteristics recorded in a circle of 1 m radius around TP/SP, cone density on the ground and distance to nearest adult juniper tree. Non-parametric Wilcoxon test for related pairs of data was applied.
