Successful spruce regenerations – impact of site preparation and the use of variables from digital elevation models in decision-making?

Within-site adaptation: Growth and mortality of Norway spruce, Scots pine and Silver birch seedlings in different planting positions across a soil moisture gradient

“…When soil moisture conditions become drier, depression and hinge positions prove to be as good options as mounds to reduce the mortality rate. In areas or occasions with low precipitation, low planting positions can even be preferred to avoid mortality due to drought when mounds run the risk of drying out (Örlander et al 1990;Luoranen et al 2018;Häggström et al 2021;Nordin et al 2022). Contradictory, silver birch seedlings planted in the elevated mounds had a rather high mortality rate, although not statistically different, it was always higher than in the hinge.…”

“…The choice of planting spot can be seen as site adaptation on a microsite level where different local site properties can be suitable for the planted seedlings to a varying degree (Luoranen et al 2018;Häggström et al 2021;Nordin et al 2022). The environment on a clear-cut leads to significant seedling stress (Margolis and Brand 1990) emphasizing the need to choose a suitable planting spot aiming at fast seedling establishment (Örlander et al 1990;Thiffault and Jobidon 2006;Marquis et al 2021).…”

Creation of Spot Mounds After Tillage by Excavators for Planting Forest Crops in the Middle Taiga Subzone of the Komi Republic

“…Дискретная (прерывистая) обработка почвы, в том числе созданием микроповышений с помощью экскаваторов при искусственном лесовосстановлении, широко применяется за рубежом [1,2]. Ее пре-имущества [3] вызвали большой интерес и в России, особенно их использование при создании микроповышений, что в определенных типах леса позволяет повысить приживаемость лесных культур [4,5], особенно  СЕЛЬСКОХОЗЯЙСТВЕННЫЕ НАУКИ  при использовании посадочного материала с закрытой корневой системой.…”
