Abstract Purpose of the Review The concept of tree-related microhabitats (TreMs) is an approach to assess and manage multi-taxon species richness in forest ecosystems. Owing to their provision of special habitat features, TreMs are of special interest as a surrogate biodiversity indicator. In particular, in retention forestry, TreMs have gained attention over the past decade as a selection criterion for retained structural elements such as habitat trees. This review seeks to (a) address the suitability of TreMs as biodiversity indicator in the context of retention forestry, (b) summarize drivers of TreM occurrence and the status quo of the implementation of TreM-based retention concepts in forest management, and (c) discuss current and future challenges to the use of TreMs as biodiversity indicator. Recent Findings The TreM concept originated in Europe where it is now increasingly implemented. Most studies of the quantity, quality, and diversity of TreMs are focused on tree species from this region, although it is increasingly applied in other contexts. In addition to tree species, tree dimensions and live status have been identified as the main drivers of TreM occurrence. One major remaining research challenge is to verify relationships between the occurrence and abundance of forest-dwelling species from different taxonomic groups and TreMs to improve the evidence basis of this concept and thus increase its integration in forest conservation approaches. Summary TreMs are not the “silver bullet” indicator to quantify biodiversity of forest dwelling species, but they provide an important tool for forest managers to guide the selection of habitat trees for the conservation of the associated biodiversity.

<p>Forests provide essential economic, social, cultural and environmental services. To be able to maintain the provision of these services, sustainable forest management (SFM) is a vital obligation. The maintenance of biodiversity, ranging from gene to ecosystem levels, is essential for functions and associated services, and it is one of the most important criterion for assessing sustainability in the Pan-European region. <br>Currently, the majority of SFM Criteria and Indicators focuses on attributes relative to tree species or to the whole forest. With reference to biodiversity conservation, this means that the collected information cannot fully assess whether forests are being managed sustainably. To understand the drivers of forest biodiversity and drive sustainable management, several taxonomic groups should be investigated, since they may respond differently to the same environmental pressures. However, up to now, broad multi-taxonomic analyses were mainly performed through reviews and meta-analyses which limit our holistic understanding on the effects of forest management on different facets of biodiversity. Recently, several research institutions took up the challenge of multi-taxonomic field sampling. These local efforts, however, have limited extrapolation power to infer trends at the European scale. It is high time to share, standardize and use existing multi-taxon data through a common platform to inform sound management and political decisions. Biodiversity indicators have also some potential to be used in evaluation of impact of forest management on soils and surface waters in terms of naturalness, degradation and reclamation.<br>We present the COST Action CA18207 “Biodiversity of Temperate forest Taxa Orienting Management Sustainability by Unifying Perspectives” (Bottoms-Up). It will gather the most comprehensive knowledge of European multitaxonomic forest biodiversity through the synergy of research groups that collected data locally in more than 2200 sampling units across approximately 300 sites covering nine different European forest types. For each sampling unit, information will be available on at least three taxonomic groups (vascular plants, fungi, lichens, birds and saproxylic beetles being the most represented) and on live stand structure and deadwood. Multi-taxon biodiversity will be associated with: (i) information on forest management based on observational studies at the coarse scale, and (ii) structural data deriving from forest manipulation experiments at the fine scale. </p><p>Specific objectives are:<br>• Developing a standardized platform of multi-taxon data;<br>• Establishing a network of forest sites with baseline information for future monitoring;<br>• Designing shared protocols for multi-taxon sampling;<br>• Assessing the relationships between multi-taxon biodiversity, structure and management;<br>• Creating a coordinated network of forest manipulation experiments;<br>• Evaluating indicators and thresholds of sustainability directly tested on biodiversity;<br>• Developing management guidelines defining sustainable management to be applied in forest certification and within protected areas.</p><p>The Action involves about 80 researchers and stakeholders from 29 countries and represents an outstanding opportunity to develop a strong network of collaboration for standardized broad-scale multitaxon studies in Europe.</p><p>Keywords:  Multi-taxon, Pan-European region, Sustainable Forest Management. </p><p> </p>

Commercial Forest

Due to traditional forest management, the primary goal of which is the production of raw wood material, commercial forest stands are characterized by low biodiversity. At the same time, commercial forests make up the majority of forests in the Central European region, which means a significant impact on the biodiversity of the entire large region. Saproxylic species of organisms are a frequently used criterion of biodiversity in forests. Based upon the analysis of 155 scientific works, this paper defines the fundamental attributes of the active management supporting biodiversity as well as the preservation of the production function. Using these attributes, a model management proposal was created for three tree species, which takes into account the results of research carried out in the territory of the University Forest Enterprise of the Czech University of Life Sciences Prague, since 2019. The optimum constant volume of deadwood in commercial stands was set at 40–60 m3/ha, 20% of which should be standing deadwood. The time framework is scheduled for an average rotation period of the model tree species, while the location of deadwood and frequency of enrichment must comply with the rate of decomposition, the requirement for the bulkiest dimensions of deadwood possible, and the planned time of tending and regeneration operations in accordance with the models used in the Czech Republic. The goal of active management is to maintain the continuity of suitable habitats for sensitive and endangered species. The estimates of the value of retained wood for decomposition can be as high as 45–70 EUR/ha/year for spruce and beech, and about 30 EUR /ha/year for oak.

Abstract. Although forest management is one of the instruments proposed to mitigate climate change, the relationship between forest management and canopy albedo has been ignored so far by climate models. Here we develop an approach that could be implemented in Earth system models. A stand-level forest gap model is combined with a canopy radiation transfer model and satellite-derived model parameters to quantify the effects of forest thinning on summertime canopy albedo. This approach reveals which parameter has the largest affect on summer canopy albedo: we examined the effects of three forest species (pine, beech, oak) and four thinning strategies with a constant forest floor albedo (light to intense thinning regimes) and five different solar zenith angles at five different sites (40° N 9° E–60° N 9° E). During stand establishment, summertime canopy albedo is driven by tree species. In the later stages of stand development, the effect of tree species on summertime canopy albedo decreases in favour of an increasing influence of forest thinning. These trends continue until the end of the rotation, where thinning explains up to 50% of the variance in near-infrared albedo and up to 70% of the variance in visible canopy albedo. The absolute summertime canopy albedo of all species ranges from 0.03 to 0.06 (visible) and 0.20 to 0.28 (near-infrared); thus the albedo needs to be parameterised at species level. In addition, Earth system models need to account for forest management in such a way that structural changes in the canopy are described by changes in leaf area index and crown volume (maximum change of 0.02 visible and 0.05 near-infrared albedo) and that the expression of albedo depends on the solar zenith angle (maximum change of 0.02 visible and 0.05 near-infrared albedo). Earth system models taking into account these parameters would not only be able to examine the spatial effects of forest management but also the total effects of forest management on climate.

Protected Forests

Protection forest becomes a forest area with the main function as protection of life support systems. The health condition of protected forests has a great influence on the environment of the ecosystem. It is important to assess the health of protected forests in view of their main function. Thus to determine the health condition of the forest, one indicator that can be used is tree biodiversity. Biodiversity is the richness of life found on earth. Assessment of biodiversity indicators is very necessary to do because it is sensitive to changes, ecological system indicators, spatial heterogeneity, temporal, and and the order in the food chain. This study aims to determine the diversity of tree species in protected forest areas managed by HKm Beringin Jaya as an indicator of forest health assessment. The study was conducted using the Forest Health Monitoring (FHM) method. The results showed that the final value of forest health status with indicators of biodiversity (tree species diversity) in the protected forest area managed by HKm Beringin Jaya was in the good category of 50% in cluster plots (2, 5 and 6) and bad by 50% on cluster plots (1, 3 and 4), thus showing that the protected forest area managed by HKm Beringin Jaya has a fairly healthy (stable) condition with a moderate category.

Abstract. Despite an emerging body of literature linking canopy albedo to forest management, understanding of the process is still fragmented. We combined a stand-level forest gap model with a canopy radiation transfer model and satellite-derived model parameters to quantify the effects of forest thinning, that is removing trees at a certain time during the forest rotation, on summertime canopy albedo. The effects of different forest species (pine, beech, oak) and four thinning strategies (light to intense thinning regimes) were examined. During stand establishment, summertime canopy albedo is driven by tree species. In the later stages of stand development, the effect of tree species on summertime canopy albedo decreases in favour of an increasing influence of forest thinning on summertime canopy albedo. These trends continue until the end of the rotation where thinning explains up to 50% of the variance in near-infrared canopy albedo and up to 70% of the variance in visible canopy albedo. More intense thinning lowers the summertime shortwave albedo in the canopy by as much as 0.02 compared to unthinned forest. The structural changes associated with forest thinning can be described by the change in LAI in combination with crown volume. However, forests with identical canopy structure can have different summertime albedo values due to their location: the further north a forest is situated, the more the solar zenith angle increases and thus the higher is the summertime canopy albedo, independent of the wavelength. Despite the increase of absolute summertime canopy albedo values with latitude, the difference in canopy albedo between managed and unmanaged forest decreases with increasing latitude. Forest management thus strongly altered summertime forest albedo.

: Under changing climatic conditions, drought may become a critical constraint for trees in urban areas, particularly at roadsides and highly paved squares. As healthy urban trees have proven to be an important mitigation and adaptation tool for climate change as well as a significant provider of ecosystem services, there is a need for planting species and cultivars capable of coping with the limited water supply. However, data on species’ and cultivars’ response to drought, particularly their water supplying root systems remains rare. To consider the whole plant responses to drought situations, we studied the growth and phenology of three frequently planted tree species and cultivars with a diameter of 5–6 cm during a one-year rainfall exclusion experiment conducted in a nursery field as well as the dry biomass of the compartments branch, stem, and root after excavation. Our results revealed that species’ and cultivars’ performance were linked to their within-plant carbon partitioning. A high tolerance to drought was noted for Acer campestre, with a particularly high ratio of root:shoot ratio, which made it presumably less susceptible to droughts. Tilia cordata ‘Greenspire’ was highly affected by the reduced water availability visible through prematurely leaf senescence, while Carpinus betulus ‘Fastigiata’ suffered from losing a considerable part of its root biomass, which resulted in the lowest root:shoot ratio of all species and cultivars. This study demonstrated the need for investigating the reaction patterns of species and cultivars by considering both the above-and the below-ground plant parts. We recommend that, for future tree plantings at harsh and challenging urban sites, an important selection criterion should be species’ and cultivars’ capability to develop and retain strong and dense root systems even under limited water supply, as that is believed to be an important trait for drought tolerance.

Stand structure and species diversity are two useful parameters to provide a synthetic measure of forest biodiversity. The stand structure is spatial distribution, mutual position, diameter and height differentiation of trees in a forest ecosystem and it highly influences habitat and species diversity. The forest stand and species diversity can be measured through indices that provide important information to better address silvicultural practices and forest management strategies in the short and long-term period. These indices can be combined in a composite index in order to evaluate the complex diversity at the stand level. The aim of the paper is to identify and to test a complex index (S-index) allowing to take into account both the tree species composition and the stand structure. S-index was applied in a case study in the north-east of Italy (Trentino province). The results show that the Norway spruce forests in Trentino province are characterized by a medium-low level of complexity (S-index is in a range between 0.14 and 0.46) due to a low tree species composition rather than to the stand structure (diametric differentiation and spatial distribution of trees).

General Guidance

Sustainable forest management ideally involves five elements: 1) establishing a clear set of values, goals and objectives and, 2) planning actions that are most likely to meet desired goals and objectives, 3) implementing appropriate management activities, 4) monitoring the outcomes to check on predictions, effectiveness, and assumptions, and 5) evaluating and adjusting management depending on the outcome of monitoring. Within this framework, indicators are used to determine whether the outcome of management has met the intended goals. In this paper we provide general guidance for developing an integrated and logical monitoring system, define and differentiate between "evaluative" and "prescriptive" indicators, provide more specific advice on choosing evaluative indicators (including a comparison of types of ecological indicators), and provide specific advice on defining prescriptive indicators. Our guidelines for developing an indicator and monitoring framework are based on three principles. The first principle is to develop a logical framework, including 1) establishing clear values and goals before setting indicators and objectives, and 2) linking prescriptive and evaluative indicators directly to plan objectives, and to each other. The second principal is to use the framework to learn adaptively by: 1) designing management activities to address specific questions, 2) learning about thresholds, and 3) testing assumptions. The third principal is to create a formal plan for learning. Key words: biodiversity, indicators, focal species, adaptive learning, sustainable forest management
