“…However, there is no agreement in the literature on the effect of forest management on soil properties, nor in relation to the effects of afforestation and managed systems in SOC [38]. Likewise, in Mediterranean mountain areas, these processes have been widely described in alkaline soils; however, less information is known about what happens in acidic soil environments [37,39].…”

“…The importance of the soil environment (acidic or alkaline) for both the SOC stock and its subsequent mineralization has thus been demonstrated. This is influenced by the nature of the litter depending on the tree species, as well as the type of past and present management [16,39,42]. This could justify why, while in a first analysis of acidic environments, we find a higher stock in afforestation sites (possible carbon saturation of the system due to the nature of the litter and the physical-chemical nature of the soil) [48,49], in alkaline soils (where the degradation of organic matter is not blocked by the acidity of the soil), the greatest contribution of carbon is produced in growing forests with a significant presence of undergrowth, at least in the first horizons [55,56].…”

Forest expansion in Mediterranean mountain areas is a widespread phenomenon resulting from the abandonment of agricultural and pastoral activities during the last century. Therefore, knowledge of the long-term storage capacity of soil organic carbon (SOC) in Mediterranean forests is of great interest in the context of global change. However, the effects of these land uses and covers (natural secondary forest, afforestation with conifers and silvo-pastoral ecosystems (dehesas)) on SOC dynamics are still uncertain. The main objectives of this study were to evaluate physico-chemical soil properties, SOC and nitrogen stocks, and SOC fractions in Mediterranean forests and to assess the effects of tree species, the soil environment (acidic and alkaline), and land management. We selected five land uses and land covers: managed and non-managed afforestation and dehesa (except for alkaline dehesa) and a stage of succession when tree species begin to become established after abandonment. This study concludes that although total SOC stocks are higher in afforested systems with conifers, SOC is stored in less stable carbon pools than in broadleaf forests. In addition, this study confirms that there are marked differences in the results between acidic and alkaline environments. Finally, the management system is also a significant factor, particularly for afforested sites.

“…For example, Kermavnar et al [25] conducted isotopic studies of Fagus sylvatica and found that trees growing on southwestern slopes experienced greater environmental stress compared with trees on slopes with different orientations, and this was attributed to differences in the strength of water evapotranspiration on slopes of different orientations. Kooch et al [69] explored the effects of soil conditions and altitude on silvicultural systems, and high altitude had an adverse effect on soil function and fertility. Overall, topography affects the distribution of environmental factors, and the responses of trees to environmental factors vary among regions.…”

We used tree-ring width data of Larix gmelinii and Pinus sylvestris var. mongolica from the northern region of the Daxing’an Mountains, China; normalized difference vegetation index (NDVI) data; and microtopographic information (elevation, slope direction, slope gradient, and topographic location index) to assess spatiotemporal dynamics in the growth of the boreal forest and topographic patterns of forest decline under the background of climate warming. Forest growth trends were determined based on tree growth decline indicators and NDVI time series trends, and topographic patterns of forest decline were analyzed using the C5.0 decision tree model. More climatic information was present in the radial growth of the trees at higher elevations, and P. sylvestris var. mongolica was influenced strongly by climatic factors of the previous year. Since 1759, tree radial growth trends in the study area have experienced two recessions during 1878–1893 and 1935–1943, which were characterized by persistent narrow whorls of tree rings of below-average growth. Changes in NDVI and tree-ring information were similar, and they together indicate a high risk of declining forest growth in the northern Daxing’an Mountains after 2010, especially at higher elevations. The NDVI time series showed that the high temperatures in 2003 negatively affected forest growth in the study area, which was confirmed by the tree-ring data. The decision tree terrain model results had an accuracy of 0.861, and elevation was the most important terrain factor affecting forest decline. The relative importance of elevation, topographic position index, aspect, and slope was 58.41%, 17.70%, 16.81%, and 7.08%, respectively. Classification rule-based decision tree models can be used to quantify the effects of terrain factors on tree growth. This research methodology can aid the management of regional forestry resources and the conservation of forest resources under the background of climate change, which increases the risk of forest decline.
