“…Other site variables may have a significant impact and should be tested. In addition to site variables, the suitability of the habitat for seed-dispersing animals and the occurrence of other masting tree species could also affect the probability of the occurrence of beech regeneration and cause the pattern of random effects (Perea et al 2011;Löf et al 2018).…”

“…Natural regeneration can play an important role in the process of converting pure coniferous stands to mixed stands by increasing the proportion of broadleaf trees (Felton et al 2016), contributing to the restoration of forests. The regeneration phase is the best opportunity to influence tree species composition and forest ecosystem structures (Fischer et al 2016;Löf et al 2018). With natural regeneration playing an expanding role in silviculture in central Europe, the monitoring of the success of regeneration in stands is an important issue for forest management.…”

“…The distance to the parent tree is relevant to seed dispersal by means of barochory and to the resulting seed density (Sagnard et al 2007). While barochory commonly results in beech nut dispersal up to a radius of 20 m (Wagner 1999;Kutter and Gratzer 2006;Millerón et al 2013), zoochorus dispersal is dependent on the suitability of the stands as a habitat for seed-dispersing animals (Löf et al 2018). Kunstler et al (2007) found beech regeneration in pine stands up to 3000 m from the nearest mature beech stand.…”

The potential utilisation of natural regeneration of European beech (Fagus sylvatica L.) for forest conversion has received little attention to date. Ecological knowledge is necessary to understand and predict successful natural regeneration of beech. The objective of this study was to improve understanding of what drives the occurrence of beech regeneration and, once regeneration is present, what drives its density. In the study, we utilised a forest inventory dataset provided by Sachsenforst, the state forestry service of Saxony, Germany. The dataset was derived from 8725 permanent plots. Zero-altered negative binomial models (ZANB) with spatial random effects were used to analyse factors influencing occurrence and density simultaneously. The results provided by the spatial ZANB models revealed that the probability of the occurrence of beech regeneration is highly dependent on seed availability, i.e. dependent on source trees in close proximity to a plot. The probability of beech regeneration rises with the increasing diameter of a potential seed tree and decreases with increasing distance to the nearest potential seed source. The occurrence of regeneration is affected by overstorey composition and competition exerted by spruce regeneration. Where sites are affected by groundwater or temporary waterlogging, the impact on the occurrence of regeneration is negative. Although distance to the nearest potential seed source has an influence on occurrence, this variable exerts no influence on density. A high regeneration density arises in conjunction with a high beech basal area in the overstorey. Beech regeneration density, but not occurrence, is negatively affected by browsing intensity. These variables can be used to predict the occurrence and density of beech regeneration in space to a high level of precision. The established statistical tool can be used for decision-making when planning forest conversion using natural regeneration.

“…Despite extensive research conducted in various countries (Löf et al 2018), there is still a lack of knowledge, so general rules for successful direct seeding cannot be deduced as the autoecology of the tree species and abiotic conditions vary greatly. Some authors emphasise that seeding, as a method of reforestation, should be promoted as this is the most environmentally acceptable method and with proper soil preparation, and seeding is not inferior to planting forest crops (Aleksandrowicz-Trzcińska et al 2017).…”

The purpose of the research is to analyse the successful creation of an artificial pine forest by seeding and develop recommendations for the guaranteed reproduction of pine stands in Northern European Russia. In recent decades, there has been a steady decline in the share of pine stands and their replacement with low-value and low-yielding tree species. We surveyed 12 permanent sample plots that were laid out in various variants of forest crops. The taxation parameters were obtained by a standard analysis of the experimental data. The evaluation parameters of the stands vary within the following limits: the average diameter of the pine trees varied from 21.9 to 30.9 cm; the total basal area of the pine varied from 19.1 to 38.8 m2∙ha–1; the average height of the pine varied from 20.1 to 26.8 m; the number of growing trees varied from 754 to 1 952 ha–1; the pines varied from 382 to 762 ha–1; the growing stocks of stands varied from 416 to 608 m3∙ha–1. The distribution of pine trees by thickness steps showed that all the studied samples were close to the normal distribution curve. The results of the correlation and multidimensional analyses showed that the creation method of the forest crops had a significant impact on the value of the taxation parameters. It was found that the best options for growing pure pine stands that can be recommended for practical production are plots with a large share of soil cultivation and the size of the seedbed.
