“…Uneven-aged forests are a result of irregular shelterwood or selective forest cutting [41]. The uneven-aged FM system is characterized by principles of perennation and the sustained yield of forest over small areas [6]. In the Mediterranean region, a transitional FM practice type is applied, namely the conversion of coppice to high forests [44].…”

“…This type of FM relies on the occurrence of shade tolerant species such as silver fir and common beech [41,52,57]. Because of the continuous renewal of the trees, as the forest is never completely cut down and always contains a variety of trees of different sizes, ages, and species, over time, it is generally assumed that this type of management is advantageous for maintaining genetic diversity and adaptability [6]. Konnert and Hussendörfer [6] compared genetic multiplicity and diversity of silver fir (Abies alba Mill.)…”

“…in two contrasting management systems-the uneven-aged ("Plenterwald") and the even-aged forest in Germany. They concluded that from a genetic standpoint, uneven-aged forests are advantageous for genetic diversity when dealing with very small stands and/or with stands with a low percentage of silver fir, while even-aged stands can be advantageous if the stand area is large, the number of reproducing silver fir trees is high, and the regeneration occurs over a long time in small patches [6]. Wernsdörfer et al [9] modelled the impact of selective cutting on genetic factors (e.g., genetic diversity, selfing, number and location of fathers, mating success, population size versus genetic diversity, etc.)…”

“…Currently, there are many different types of FM practices, determined by factors such as climatic zones, forest types, site conditions, and even by the traditions of local societies [5]. Since 2000, a number of studies have been carried out to evaluate the impact of forest management on the genetic composition of various stands (e.g., [6][7][8][9][10][11][12][13][14][15]), with most of them focusing on a certain species or on a certain silvicultural system/management operation. Although the results derived from these studies are contradictory, most of them have found a management-associated impact on genetic structure and variation.…”

The conservation and sustainable use of forests and forest genetic resources (FGR) is a challenging task for scientists and foresters. Forest management practices can affect diversity on various levels: genetic, species, and ecosystem. Understanding past natural disturbance dynamics and their level of dependence on human disturbances and management practices is essential for the conservation and management of FGR, especially in the light of climate change. In this review, forest management practices and their impact on genetic composition are reviewed, synthesized, and interpreted in the light of existing national and international forest monitoring schemes and concepts from various European projects. There is a clear need and mandate for forest genetic monitoring (FGM), while the requirements thereof lack complementarity with existing forest monitoring. Due to certain obstacles (e.g., the lack of unified FGM implementation procedures across the countries, high implementation costs, large number of indicators and verifiers for FGM proposed in the past), merging FGM with existing forest monitoring is complicated. Nevertheless, FGM is of paramount importance for forestry and the natural environment in the future, regardless of the presence or existence of other monitoring systems, as it provides information no other monitoring system can yield. FGM can provide information related to adaptive and neutral genetic diversity changes over time, on a species and/or on a population basis and can serve as an early warning system for the detection of potentially harmful changes of forest adaptability. In addition, FGM offers knowledge on the adaptive potential of forests under the changing environment, which is important for the long-term conservation of FGR.
