Abstract Under the current climate change conjuncture, understanding the forest plantations capacity of acclimation to warming and increased drought stress is crucial for forest managers. To get some understanding of their adaptability, plantations of similar provenance but located in climatically contrasting sites can be compared. Here we study the growth dynamics and their relationship with climate and drought in two Scots pine (Pinus sylvestris L.) plantations located in the center (Sierra de Guadarrama, wetter site) and south (Sierra Nevada, drier site) of Spain, the latter situated at the southernmost distribution limit of the species. Our objectives are to quantify the trends in radial growth of these plantations, to quantify the influence of climate on growth, and to project the plantations growth as a function of forecasted climate. Results reveal that the plantations from the drier site show lower, and less responsive to climate, growth and greater resilience than those from the wetter site. Furthermore, if the current climate-growth relationships continue in the future, these plantations would maintain the current limited growth rate during the 21st century. On the contrary, plantations from the wetter site show higher growth rate and more resistance to drought, and they are projected to increase growth under the warmer conditions forecasted for the 21st century. Our study shows that plantations in drier sites may have a great capacity to acclimate to local climate conditions and would not be negatively impacted by the projected climate warming.

苏格兰松种植园在该物种最南端分布极限地区的生长适应气候变暖

摘要 在当前气候变化形势下,了解人工林适应气候变暖和干旱胁迫的能力对于森林管理者至关重要。为了了解它们的适应性,可以比较具有相似出处但位于气候相反地点的种植园。在这里,我们研究了位于西班牙中部(瓜达拉马山脉,湿润地区)和南部(内华达山脉,干旱地区)的两个苏格兰松(Pinus sylvestris L.)种植园的生长动态及其与气候和干旱的关系,后者位于该物种分布的最南端。我们的目标是量化这些人工林径向生长的趋势,量化气候对生长的影响,并将人工林的生长预测为预测气候的函数。结果表明,与来自湿润地区的种植园相比,来自干燥地区的种植园对气候、生长和更大的恢复力的响应较低,对气候、生长的反应也较弱。此外,如果当前的气候增长关系在未来继续下去,这些种植园将在 21 世纪保持目前有限的增长速度。相反,来自较湿润地区的种植园显示出更高的生长速度和更强的抗旱性,预计它们在 21 世纪预测的温暖条件下会增加生长。我们的研究表明,在较干燥地区的种植园可能有很强的适应当地气候条件的能力,并且不会受到预计的气候变暖的负面影响。生长和比潮湿场地更大的弹性。此外,如果当前的气候增长关系在未来继续下去,这些种植园将在 21 世纪保持目前有限的增长速度。相反,来自较湿润地区的种植园显示出更高的生长速度和更强的抗旱性,预计它们在 21 世纪预测的温暖条件下会增加生长。我们的研究表明,较干旱地区的种植园可能有很大的能力适应当地的气候条件,并且不会受到预计的气候变暖的负面影响。生长和比潮湿场地更大的弹性。此外,如果当前的气候增长关系在未来继续下去,这些种植园将在 21 世纪保持目前有限的增长速度。相反,来自较湿润地区的种植园显示出更高的生长速度和更强的抗旱性,预计它们在 21 世纪预测的温暖条件下会增加生长。我们的研究表明,较干旱地区的种植园可能有很大的能力适应当地的气候条件,并且不会受到预计的气候变暖的负面影响。来自较湿润地区的种植园显示出更高的生长速度和更强的抗旱性,并且预计它们将在 21 世纪预测的温暖条件下促进生长。我们的研究表明,较干旱地区的种植园可能有很大的能力适应当地的气候条件,并且不会受到预计的气候变暖的负面影响。来自较湿润地区的种植园显示出更高的生长速度和更强的抗旱性,并且预计它们将在 21 世纪预测的温暖条件下促进生长。我们的研究表明,较干旱地区的种植园可能有很大的能力适应当地的气候条件,并且不会受到预计的气候变暖的负面影响。
