As a result of climate change, the frequency and intensity of disturbances are increasing, negatively affecting the stability and functioning of forest ecosystems. Increase in temperatures and changes in precipitation patterns are weakening the vitality of native tree species, leading to higher mortality, stand disintegration, soil erosion, and reduced water retention. It is therefore essential to identify more resilient species, including introduced tree species that exhibit greater resistance to extreme environmental conditions. This study evaluated the growth performance and health status of 9 introduced conifer species (Pseudotsuga menziesii, Pinus nigra, Cedrus spp., Abies spp., Thuja spp.) in comparison with the native silver fir (Abies alba) at the site of a former forest nursery in Budišov. More than 5,000 seedlings were monitored for mortality, vitality, total height, height increment, and root collar diameter. Significant differences were observed across all assessed parameters. Pinus nigra, Thuja plicata, and Abies grandis showed high potential as alternative species for forest regeneration. Their use may enhance species diversity and contribute to forest adaptation under climate change. However, appropriate provenance selection, mixed-species planting, and long-term monitoring are crucial.
