In the time of ongoing climate change and the increasing area of post-mining landscape, the successful afforestation of reclamation sites by suitable adaptive tree species is gaining in importance. One of possible ways may be the use of introduced tree species, which is, however, a controversial topic in relation to risks for forest management and nature conservation. The objective of this study was to comprehensively evaluate the forest stands (age 48 years) of 9 introduced and 3 native coniferous tree species in lowland post-mining coal site of the Czech Republic. The research was focused on production potential, health status, resistance to climate change, carbon sequestration, biodiversity and soil properties. The highest timber production, biomass and carbon stock (49–95% above average), was observed in case of Pinus sylvestris, P. nigra and Pseudotsuga menziesii. On the other hand, unsuitable habitat, insect and pathogens caused poor health status and extremely low production parameters (by 55–62% than average) in Pinus strobus and P. rotundata. In terms of climate, Pinus sylvestris, P. nigra, Larix decidua, Pseudotsuga menziesii and Picea omorika were the most resistance tree species in relation to climatic extremes. Conversely, Pinus rotundata, P. strobus, P. ponderosa, Picea pungens and P. abies were very sensitive to climate events, especially to the lack of precipitation in vegetation period with synergism of high temperature. In terms of soil parameters, the content of plant available nutrients (K, Ca, Mg) was adequate except P deficiency. The highest soil reaction was detected for Pinus nigra and P. sylvestris (pH 6.9–7.1) compared to Picea mariana (pH 4.8). The benefits of “suitable” introduced tree species (Pinus nigra, Pseudotsuga menziesii) are high timber production potential and good adaptation and mitigation of the changing climate; however, native tree species (Pinus sylvestris, Larix decidua) can provide better environmental benefits on reclamation sites.

森林开垦的生产潜力、生物多样性和土壤特性:气候变化下引入针叶树种的机会或风险?

在持续的气候变化和采矿后景观面积不断增加的时代,通过合适的适应性树种成功地在开垦场地造林变得越来越重要。一种可能的方法可能是使用引进的树种,然而,这是一个与森林管理和自然保护风险相关的有争议的话题。本研究的目的是综合评估捷克共和国低地采煤场中 9 种引进和 3 种本地针叶树种的林分(树龄 48 年)。研究的重点是生产潜力、健康状况、对气候变化的抵抗力、碳固存、生物多样性和土壤特性。在以下情况下观察到最高的木材产量、生物量和碳储量(高于平均水平 49-95%)Pinus sylvestris、P. nigraPseudotsuga menziesii。在另一方面,不适宜生境,昆虫和病原体引起的健康状况不佳状况和极低的生产参数(比平均55-62%)在北美乔松P.叶蜂。气候方面,樟子松、黑松落叶松孟氏紫杉和大松云杉是对极端气候抵抗力最强的树种。相反,Pinus rotundata P. strobus P.ponderosa Picea pungensP. abies对气候事件非常敏感,特别是对植被期降水不足与高温协同作用。在土壤参数方面,除缺磷外,植物有效养分(K、Ca、Mg)含量充足。与云杉(pH 4.8)相比,黑松樟子松(pH 6.9–7.1) 的土壤反应最高。“合适的”引进树种(黑松、Pseudotsuga menziesii)的好处是木材生产潜力高,能很好地适应和缓解气候变化;然而,本地树种(樟子松落叶松)可在填海区提供更好的环境效益。
