“…In particular, we noticed a lower density of lateral and fine roots in A. sachalinensis than in other species. This result corresponded to the previous suggestions that the horizontal distribution of root systems should serve as the major resistance to windthrow (Krause et al, 2014), and few large trees can rely solely on tap roots and need to develop thick lateral roots to prevent uprooting (Crook and Ennos, 1998).…”

“…As trees grow in size, their root system develops greater strength (Crook and Ennos 1998;Mickovski and Ennos 2003). The ability to support trees depends on root spread (Mergen 1954;Nicoll and Ray 1996;Tobin et al 2007), root architecture (Coutts et al 1999;Dupuy et al 2005;Ji et al 2007;Khuder et al 2007;Gilman and Masters 2010;Krause et al 2014), soil type (Mattheck et al 1997;Moore 2000;Dupuy et al 2005;Ji et al 2007;Ow et al 2010), and root-plate development (Dupuy et al 2005;Fourcaud et al 2008;Lundström et al 2009;Dupuy et al 2007;Ghani et al 2009). While soil conditions (type, texture, and moisture content) are important factors (Day et al 2010) in root/tree stability, this review is concentrating on the root system's influence on tree stability.…”

Over the last 30 years, researchers have begun to employ biomechanical principles to understand the stability of urban trees. This review concentrates on literature pertaining to trees in temperate urban landscapes, but also includes relevant work from other disciplines and climates as appropriate. The load-bearing capacity of a tree depends on its size and shape and the material properties of its wood. As the trunk and branches increase in diameter, their load-bearing capacity increases. Material properties (e.g., moduli of elasticity and rupture) describe intrinsic wood stiffness and strength, which influence deflection under load and load-bearing capacity, respectively. In wood, material properties vary in relation to a variety of factors, including the direction of loading, moisture content, and tree age. Wood decay reduces a tree’s load-bearing capacity. Although practitioners have developed guidelines to assess its effect, existing guidelines should be investigated, refined or rejected on the basis of rigorous scientific testing. Static load tests have been developed to address this question, as well as investigate the likelihood of uprooting, which accounts for up to 35% of tree failures. While much has been learned, many questions remain about the static load-bearing capacity of trees growing in urban landscapes.

“…With the increase in thinning intensity and the death of residual roots, the remaining trees will absorb more nutrients and water resources by promoting the growth of roots (Krause et al, 2014; Lemay et al, 2018; Olesinski et al, 2012), what is more, improving the photosynthetic capacity of the remaining plants to increase tree growth and water use efficiency (Giuggiola et al, 2013; Hawthorne et al, 2013; Lagergren et al, 2008; Niccoli et al, 2020). Additionally, soil water content is strongly affected by rainfall infiltration and groundwater recharge (Wu et al, 2021).…”

Thinning effects on forest production and rainfall redistribution: Reduced soil water deficit and improved sustainability of semiarid plantation forestlands

Large-scale planted afforestation worldwide has exacerbated soil desiccation and led to a serious shortage of water resources for forests sustainability in semiarid areas.Consequently, thinning is discussed as an important management approach to conserve water resources and to maintain plantation forestland sustainability. Here, we explored the effects of thinning intensity on semiarid forest production and soil water supply. Three artificial forests of Populus cathayana with an age of 15 yr were selected and thinned with different intensities [1/3 amount of trees removed (T 1/3 ), 2/3 amount of trees removed (T 2/3 ), and using no thinning (NT) as a control]. Results showed that thinning presented a significant impact on the above-ground threedimensional structure of planted forests and increased forest gaps. Meanwhile, the rainfall redistribution pattern changed significantly. Thinning increased throughfall
