“…This is for economic reasons [75]. As stated by Dobrovolny et al [76], the current management system in Czech floodplain forests (outside protected areas) should be gradually converted to the Croatian model of forest management, with a multilayered forest structure [77] that is more focused on individual tree growth and stability for trees with high economic value and high reproductive potential.…”

Sustainably managed forests provide multiple ecosystem services in cultural landscapes, including maintaining biodiversity. Better understanding of the benefits regarding the biodiversity of different silvicultural practices is important for sustainable landscape management. Conservation targets in forested landscapes should be determined by land managers and policy-makers, based on serious ecological research. This study deals with response of bird diversity to three different habitat types of temperate hardwood floodplain forests, which reflect specific forms of forest management. Research was based on long-term field bird census in the years 1998 to 2002 applying the point count method. Data was analysed using regression analysis with dummy variables. The results of the study indicate that hardwood floodplain forest heterogeneity, supported by different types of forest management (old-growth forest protection, group-selection harvesting and forest edge protection), provides large-scale habitat mosaic conditions suitable for many breeding bird species with different ecological niches. This result suggests that comparison of bird diversity response to different forest management types can be used as a decision support tool for sustainable landscape management strategy and local management practices in forested cultural lowland landscapes. Improvements in both regional and local ecological knowledge are generally needed in order to control floodplain land use decisions, which are typically made on the scale of landscape management. 2 of 15 above transition zones, below which, species loss is likely to occur. Forest ecosystems are crucial in maintaining climate, biodiversity and human well-being [7]. At the landscape scale, the benefits produced by forests are strongly influenced by forest management [8]. This is especially important in cultural lowland landscapes along large rivers, areas which have suffered from a significant decline in riparian floodplain forests [9].In the European temperate zone, hardwood floodplain forests (HFF) are endangered habitats. HFF provide various important ecosystem services in the lowland landscapes [10]. Land use changes and land use intensification induced by human activities are closely connected to the current ecological status of HFF in many European regions [11]. Despite centuries of intense human pressure, HFF are forest ecosystems with very rich alpha-biodiversity on the scale of individual trees and on the scale of forest stands [12,13]. A mosaic of floodplain forest habitats (including rivers and wetlands) creates a unique ecological gradient of beta-biodiversity [14]. Thus, HFF are key ecosystems in the maintenance of biodiversity on the scale of lowland riparian landscapes [15]. Because of their high biodiversity value, the natural and semi-natural remnants of HFF are usually included in ecological networks in a landscape [16]. They are also protected within the framework of international (such as the Natura 2000 European Network) or national systems for protected area...

“…The abundance and frequency of oak fructification as well as the success of natural regeneration depend on many abiotic (climatic influences primarily) (Kelly, 1994;Koenig et al, 1996Koenig et al, , 2010Gradečki-Poštenjak et al, 2018), biotic (damage by various pests, diseases and browsing animals) (Downs & McQuilkin, 1944;Beck & Olson, 1968;Chalupa, 1973;Meshkova & Didenko, 2014;Gradečki-Poštenjak et al, 2018) and anthropogenic (forest management) factors (Sork, 1993;Dey, 1995;Healy et al, 1999;Matić et al, 1999;Klimo et al, 2008;Martiník et al, 2014;Dobrovolný et al, 2017).…”

“…Stand characteristics, such as site type, stand origin, composition, age, stock density, phenological form, Kraft class, and crown projection area are particularly essential for the expected acorn yield and, accordingly, for the future cultivation of valuable timber (Beck & Olson, 1968;Chalupa, 1973;Sork, 1993;Dey, 1995;Matić et al, 1999;Wright et al, 2005;Paine & Beck, 2007;Didenko, 2008a;Didenko, 2008b;Klimo et al, 2008;Martiník et al, 2014;Dobrovolný et al, 2017, Slepykh & Korshikov, 2017. For the northeastern part of Ukraine, these issues have been covered in scientific works only in fragments (Didenko, 2008a;Didenko, 2008b) and therefore are very relevant now.…”

We analysed the quantity and quality of Quercus robur L. acorns after years with a very poor yield under the canopy of natural oak stands of various compositions, ages and stock densities in the northeastern part of Ukraine. We determined the mass of 1,000 healthy and damaged acorns of the current year. The levels of variability were estimated for the number and mass of acorns under the canopy of the studied stands. The dependences of the number of acorns on the age of oak stands and their stock density were studied. The total number of acorns under the canopy of natural oak stands was 9,900–19,000 seeds per hectare with a total mass of 26.8–54.1 kg per hectare in 2020 and 8,600–17,200 seeds per hectare with a total mass of 22.7–48.4 kg per hectare in 2021. The proportion of damaged acorns was about 70% both in 2020 and 2021. The largest number of acorns was concentrated under healthy trees (without signs of decline) that had a well-developed crown and, therefore, received more sunlight and heat. The identified quantitative and qualitative estimates and acorn spreading pattern need to be considered when selecting sites for further natural seed regeneration in old-aged oak stands.

“…Tree species such as lime Tilia cordata, maple Acer platanoides, and fluttering elm Ulmus laevis in Latvia have still been little studied, most likely because stands of these species are rare in Latvia -oak stands 0.33%, lime stands 0.07%, fluttering elm and wych elm stands 0.07% and maple stands 0.53% (State Forest Service, 2020). Studies elsewhere in Europe show that oak and lime stands are able to be productive with stock up to 700-900 m 3 •ha -1 (Shvidenko et al, 2008;De Jaegere et al, 2016;Dobrovolny et al, 2017). In Lithuania, on the most fertile site types, in 70-to 100-year-old lime stands the mean accumulated growing stock volume comprises 300-330 m 3 •ha -1 (Semaðkienë, 2006).…”

Climate forecasts indicate that in the future the climate will become more and more suitable for growth of broad-leaved tree species in Latvia. It is therefore very important to recognise and understand the growth potential of these broad-leaved stands in Latvia and the factors affecting the increment of growing stock. The results of the study showed high volume yield, as already 60- to 80-year-old stand stock could reach 500–600 m3·ha-1, and in later years even 700–1000 m3·ha-1. Similarly, the results of our study showed that the increment of the stock and growth potential of individual forest elements varied significantly between the various broad-leaved species. Significant factors were the age of the forest stand or forest element (a set of trees of the same species, in one layer and belonging to one generation), the indicators of competition (basal area and/or relative density) and the indicators of the social status of the forest element, namely, the ratio of the mean diameter of the forest element and the mean diameter of the dominant species of the upper layer of the stand and the sum of the basal area of the larger forest elements). No significant differences were found in growing stock and growth potential between monospecies and mixed stands and between simple and complex stands, neither at the level of the stands, nor at the level of the individual forest element.
