At air-polluted sites, Macedonian pine (MCP) was found to withstand harsh conditions, where sulfur dioxide induced Norway spruce (NS) die-off. Despite MCP is a native species in the Balkans only, it is mixed with NS frequently. It has been more than 30 years since a planting experiment was established in the Jizera Mts., where MCP’s capability of thriving within the large post-calamity clear-cut was tested. The objective of the study was to compare the performance of MCP with nearby standing NS of the same age and also analyze forest floor properties. The results showed that performance of MCP was similar to that one of NS in the conditions of the study site. The MCP differed principally in higher basal area due to forked stems and heavier organic forest floor of litter-fall origin, which was lower in plant-available nutrients. The pH KCl matched with differences in basic cations contents and their saturation.
