Special Issue Information

Dear Colleagues,

In the face of environmental change, mixed-species forests are considered one of the most important measures of climate-adopted forest management in many places of the world. According to many studies, a mixed-species forest seems to be more resistant and more resilient to climate-induced change. Furthermore, their role in providing many non-timber goods and services, such as regulating, cultural, and supporting services, is recognized as an important factor contributing to human wellbeing. Knowledge about their functioning and management under changing climate conditions is still fragmented and does not allow for a global or specific and sound-based overview of their performance. We still do not know how mixed-species forests behave under climate change. In many cases, our understanding of their performance is derived from monocultures which behave sometimes completely different.

This Special Issue of Forests will comprise selected papers dealing with advanced research on mutual relationships between tree species in a stand, and the functioning of mixed-species forests on different stages of development and along with ecological gradients under conditions of climate change. Special attention should be paid to how predicted changes of the climate effect inter-specific relationships, resulting in productivity, ecological stability, wood quality, resistance, and resilience to climate events (drought, storm, frost, etc.) of various species’ configurations. The understanding of these processes should be a foundation of appropriate silvicultural prescriptions within the management of mixed-species forests, considering climate change scenarios. Any contribution related to the quantity and quality of the research-based estimation of stand regeneration methods, tending operations on different stages of stand development (pre-commercial and commercial thinning), silvicultural systems, and silvicultural planning in the management of mixed-species forests in the face of climate change are welcome. Additionally, we are looking for study results on methods of multi-species afforestation and any aspects of growth models, including climate change scenarios, used as a decision support system in mixed-species forest management.

Mixed cropping might be seen as an alternative to monocultures by better protecting biodiversity and improving ecosystem services and resources. In the presented study, we tested the genetic and ecological effects of pure and mixed propagation of different poplar hybrids planted together with black locust trees. Poplar (Populus) hybrids are widely used for bioenergy in monoculture systems due to their rapid and high biomass production. Black locust (Robinia pseudoacacia L.) is a species with the ability to fix nitrogen and seen as a promising candidate for mixed cultivation. Eight different poplar hybrids and black locust trees from three provenances planted in two study sites with different environmental conditions were tested in varying combinations in pure and mixed stands to observe effects of the different hybrids and genotypes, site conditions and the mixed growing on the performance of poplar and its gene expression. Transcriptome analyses of leaves from four poplar clones selected according to their divergent growth performance were conducted to study differential gene expression that can be an important indicator of differences in growing conditions and success. Differences in gene expression were most pronounced among hybrids and different genotypes of the same hybrid, followed by the study site influence, and were least pronounced between mixed and pure stands. The genotypes of the same hybrid were clearly separated from each other. Clear separation between the study sites for all clones was also observed. Only a few genes were differently expressed in pure vs. mixed stand comparisons for each clone, but there were no common genes that were differently expressed in pure vs. mixed stands in all clones. In total, 199 genes showed differential expression between the study sites regardless of poplar clone or type of stands. The analysis suggested that plant genotypes and environmental conditions were more important at the early stage of stand development than pure or mixed cultivation. Full article

This paper presents a simulation of the regulation of Araucaria angustifolia (Bertol.) Kuntze timber stocks using Liocourt’s law. Although this species is currently protected by law, recent government initiatives are being considered to propose sustainable forest management practices by selecting small rural properties in Southern Brazil. Here, we simulate the applicability of Liocourt’s law in a typical rural property, the size of which is approximately 85 ha. Forest inventory measurements were conducted by estimating the diameter at the breast height (d), total height (h), and annual diameter increments of 308 trees that fit the criteria of d ≥ 10 cm, distributed on 35 permanent plots of 400 m2 each. As a result, a reverse J-shaped d distribution was found. On average, 303 trees can be found per hectare (ha). Local allometric equations showed their basal area (G) to be 21.9 m2∙ha−1, and their commercial volume (V) to be 172 m3∙ha−1, whereas Liocourt’s quotient (q) was 1.31. Based on these attributes, nine different forest management scenarios were proposed by simulating a remaining basal area (Grem) of 10.0, 14.0, and 18.0 m2∙ha−1, and Liocourt’s quotient was changed to 1.1, 1.3, and 1.5. All scenarios consider a d of 62.5 cm. In the less intensive scenario (i.e., q value = 1.5 and larger basal area of 18.0 m2·ha−1) there is greater optimization of space, and higher economic return is ensured to rural producers due to the definition of shorter cutting cycles. This also allows a faster growth rate in both d and h for smaller trees, due to the higher incidence of light onto the lower canopy layer, increasing the natural regeneration implementation of other native species. Forest management should thus be considered a goal in addition to consumer market characteristics for defining the ideal timber stock scenario. Full article
