An article about the famous Far Eastern forester, Doctor of Biological Sciences, Professor, Honored Forester of Russia Yuri Ivanovich Manko (25.11.1931 – 19.02.2021). After graduating from the Siberian Forestry Institute in 1954, he was assigned to the Far Eastern branch of the SB Academy of Sciences of the USSR named after V.L. Komarov and taken to the Department of Botany and Plant Science in the Laboratory of Forestry, which was organized and headed by Professor Boris Pavlovich Kolesnikov. In 1966, already as part of the Biology and Soil Sience Institute, established in 1962, the laboratory was reorganized into a non-structural forest Department. In 1962, Yu.I. Manko defended his Candidate thesis «Natural regeneration of fir-spruce forests of the northern half of Sikhote-Alin and some issues of their structure and development», in 1985 – his doctoral dissertation «Ayan spruce (distribution, biology, classification of forest types, features of age structure and dynamics of phytocenoses». The scientific heritage of Yuri Ivanovich exceeds 330 publications on forestry, botany, soil science, botanical geography, history of science, nature conservation issues. Yuri Ivanovich Manko throughout his scientific activity developed and promoted the «genetic» or «geographical-genetic» direction of forest typology closely related to the forest formation process, which was developed on the basis of the scientific heritage of B.A. Ivashkevich-B.P. Kolesnikov. He supplemented the theory of the forest formation process by characterizing the zonal features of this process in the area of the Ayan spruce with autogenous vegetation development and exogenous destructive effects. They were shown that the spectrum of particular forest-forming processes is specific for various sub-formations and geographical facies, and their dynamics depends on geomorphological conditions and the speed of modern reliefforming processes. The name of Yuri Ivanovich Manko is inscribed in the history of Far Eastern science as an outstanding researcher of forests.

The University of Guelph is a mid-sized university in southern Ontario that has many historical underpinnings with respect to both undergraduate and graduate education in forestry and forest-related subjects. Some of the earliest forward-thinking forest policies found in Ontario came from early faculty associated with the predecessor of the University, the Ontario School of Agriculture. Today, the University has numerous faculty in Colleges across campus that are involved in a multitude of teaching and research aspects associated with forested environments. The research-teaching link with respect to forestry is strong and the undergraduate population appears appreciative of this. Undergraduate courses and course segments at both undergraduate and graduate levels exist, and a minor in forest science, housed in the Department of Environmental Biology but drawing on resources from across multiple disciplines, is also available. The University of Guelph is currently evaluating its options with respect to undergraduate education in the forest sciences. Building on past and present strengths, the University is considering offering a non-accredited B.Sc. program that embraces the science and management of forests and the environmental impact and community benefits associated with interventions in the forest. Key words: Ontario forests, historical perspectives, learner-centred undergraduate curriculum, forest environments, forest science, forest and natural resource economics, internationalism, non-accredited B.Sc. undergraduate degree, graduate forest research

The survival of Rottenburg University of Applied Sciences (HFR) was repeatedly questioned politically in the mid-1990 s. This had nothing to do with the fact that well-trained forestry academics were no longer needed, but had been triggered by fiscal policy savings. The applied Universities with forestry programs (five) and forestry faculties (four) in Germany are rather small and had no strong lobby like the forestry itself. Unlike some competitors, in this precarious situation, the universities did not opt for a change in their clear forestry profile, but for a broader, future-oriented understanding of modern forestry. For this purpose, they are orientated on the experience from their own past and the discipline, analyse the developments in the industries and sectors that are close to forestry and specifically sought strategic partnerships in order to be able to expand their own field of competence. Thus, the conviction for their own development process originated, that the forestry science has come in its history from the practice, passing a period influenced by knowledge of the general sciences. After that, the universities joined a phase of the development of forestry disciplines, and now they must turn back to the practice again. In this sense, a circle seems to close here and the universities have an additional, important task to deal with: more than before, in addition to teaching and research, the transfer of research results must also be put into practice. At the same time, the process of teaching has to be designed in such a way that it also provides continuous offers for job oriented training. Therefore, the universities must be the melting pot for all relevant influences from other sciences, which are and will be important for the forestry practice. This does not create a new profile, but a broader one. As a result, we are no longer training largely equal graduates, but forestry graduates with very individual strengths, attains, and profiles who fit like different keys into the various locks of practical challenges. This path helped the HFR to safeguard its future, to meet high demand among young students and to be recognized as the "smallest university of excellence" in Germany.

As the forestry profession evolved from extractive management to sustainable forest management, forestry education and curricula had to reflect these changes. While forestry education and curriculum have been extensively analyzed for different countries, no such analysis exists for Turkish forestry. This study analyzes the curriculum and course contents of all undergraduate-level forest engineering programs across Türkiye. The study employed content analysis to explore disparities among the schools. The courses are classified into disciplinary fields depending on their contents. Verbs used in learning outcomes were analyzed using Bloom’s taxonomy. Mandatory and elective requirements of forestry programs are quite similar, indicating little disparity among schools in different regions. Course categorization reveals that forestry education emphasizes biophysical and technical sciences. Learning outcomes focused heavily on the low-level thinking dimensions of Bloom. We conclude that the Turkish forestry curriculum needs a reformative change to equip students with skill sets to practice sustainable forest management.

Solid foundations and necessary change in forestry training (essay) With climate change and new demands from the public, the framework conditions of forestry work have changed significantly. More and more, foresters' competences must be wide, sound and interdisciplinary. For training, the biggest change has been the opening of a technical high school (Haute école specialisée) pathway in the space between the technical school (Ecole supérieure specialisée) and the Swiss Federal Institute of Technology in Zurich (ETH). The forest services would like to see pathways open up at Zollikofen towards a Masters in Life Sciences or other postgraduate qualifications (Master of Advanced Studies, specialised Certificates of Advanced Studies), so as to complete the range of training opportunities, from basic to postgraduate, which is necessary to understand the complexity of the forest system and hold responsible jobs. As for ETH Zurich, the forestry training has changed name and image, and is not well known to the public. It is therefore necessary to put it under the spotlight and promote it.

As part of the programme BA Forest Engineering at Hochschule WeihenstephanTriesdorf, University of Applied Sciences (HSWT), Department of Forestry we introduced a Forest Training Trail (FTT) to complement our curriculum with a strong focus on applied training in the field. The core of the FTT is (i) the trail itself with several sites with different focus and (ii) a questionnaire. Every semester a new trail at a new site within the training forest is set up. Usually, the trail encompasses four to six stations, each station representing a thematic focus of the training in the BA 'Forest Engineering', e.g. vegetation, silviculture, hunting, environmental protection, soil or other aspects. The students form teams of three and walk the FTT with a questionnaire and a map of the trail. After the deadline for handing in the questionnaires a master solution of the FTT is published on the faculty homepage in order to give students an opportunity for a self-feedback. The results of the regular evaluation show a high acceptance by the students. Our conclusion after four years of experience with the FTT is that the design as competition and game including a trophy resulted in a very high acceptance and participation with joy.

Streszczenie:

Forestry operations in Sweden can be traced a long way back in history. The overall emphasis has traditionally been on the forests’ economic or profitable role, even though they are also of great ecological and social interests. Nevertheless, the focus has shifted during the last decade due to the impact of sustainable development. A new Forestry Act has now provided the Swedish forestry with a new policy which is guided by two equally-weighted objectives; production and environmental concern. The European Union (EU) has also adapted to the direction of sustainable development. It places particular interest in the creation of sustainable coastal areas within the union.

The aim of the Bachelor of Science thesis was to investigate how Swedish coastal forest owners define their role in the creation of sustainable coastal forests. The study is built on interviews which were conducted with seven forest owners, all of whom have properties in the coastal zones of Östergötland and Kalmar. These two counties are situated in the south-eastern part of Sweden.

The study raises three different issues. The first is the manner in which the informants shape their knowledge of the existing forestry legislation, based on their identities and responsibilities. The second concerns the preconditions with which they are faced when managing their coastal forest properties and whether or not they see the new legislation as a shift in focus. The final issue highlights the importance of local knowledge and looks at the participation of the informants in the development of new regulations.

The following conclusions are drawn from the investigations. Many owners of forest properties do not identify themselves as forest owners; it is therefore important to be aware of this distinction which is made between being a forest owner and being the holder of a forest property. The coastal forest owners who were interviewed run their forests according to their individual situations. Because of this they do not appear to be part of any shift of focus within the Swedish forestry. As a result, they may not have a defined role in its development. This role would probably be clearer or greater if their local knowledge were more explicitly valuated.

Forests play a crucial role in preserving terrestrial biodiversity, producing renewable raw materials, and in reducing the scale and impact of climate change. Proper forest management is therefore crucial for today's society. For these reasons, forestry education is no less important because its aim is to educate highly qualified professionals capable of meeting current challenges. Forestry education has already had a relatively rich history, in many European countries over 100, even 200 years. A very important role in forestry education has always been played by the forest itself, which has been the place of teaching and the largest research laboratory. However, given the rapid advances in science and technology development, it is necessary to redefine the place and importance of the forest for university forestry education at present.

Pełny tekst źródła
Streszczenie:
Climate change is expected to drastically change the environmental conditions which forests depend. Lags in tree species movements will likely be outpaced by a more rapidly changing climate. This may result in species extirpation, a change in forest structure, and a decline in resistance and resilience (i.e., the ability to persist and recover from external perturbations, respectively). In the northern Great Lakes region of North America, an ecotone exists along the boreal-temperate transition zone where large changes in species composition exist across a climate gradient. Increasing temperatures are observed in the more southern landscapes. As climate change is expected to substantially affect mid-continental landscapes, this region is especially vulnerable to climate change. My research assessed the effects of climate change under business as usual (BAU) management as well as alternative management strategies. To do so, I simulated forest change in two landscapes (northeastern Minnesota and northern lower Michigan) under three climate change scenarios (current climate, low emissions, and high emissions), and four management scenarios (BAU, modified silviculture, expanded reserves, and climate suitable planting) with a spatially-explicit forest simulation model from year 2000 to year 2150. Specifically, I explored how climate change would affect relationships between tree species diversity and productivity; how expanded reserves and modified silviculture may affect aboveground biomass (AGB) and species diversity; how climate suitable planting may affect functional diversity, and AGB; and how alternative management may affect the resistance and resilience of forests to multiple disturbances interacting with climate change. Under the BAU management scenario, I found that current and low emissions climate scenarios did not affect the relationship between species diversity and productivity; however, under a high emissions climate scenario, a decline in simulated productivity was coupled with a stronger positive relationship between diversity and productivity. Under the high emissions climate scenario, overall productivity declined in both landscapes with specific species declines projected for boreal species such as balsam fir (Abies balsamea) and black spruce (Picea mariana). Under alternative management scenarios, I simulated a limited ability to increase tree species and functional diversity, AGB, and net primary productivity under climate change. The limits of management were especially apparent under the high emissions climate scenario. In a novel approach to measuring resilience, I plotted the recovery of both initial species composition and AGB to stochastic fire events for each simulation. This approach assessed both a general response (i.e. AGB) with a more specific response (i.e. species composition). My results suggest that climate change will reduce the resilience of northern Great Lake forest AGB and species composition and that management effects will be largely outweighed by the declines expected due to climate change. My results highlight the necessity to consider even more innovative and creative solutions under climate change (e.g., planting species from even further south than I simulated).

Streszczenie:
Forest roads and stream channels are mapped using a variety of remote sensing and ground-based techniques. In densely forested areas, conventional remote sensing methods provide limited terrain information, while ground-based surveys can be time-consuming, difficult, and expensive. Light Detection and Ranging (LiDAR) is an airborne remote sensing technology used to create high-resolution digital elevation models (DEMs) of the earth’s surface. This study tests the accuracy of forest road and stream channel features mapped using LiDAR in the steep, forested terrain of California’s Santa Cruz Mountains. A conventional total station survey was used to determine centerline position and elevations along a four-kilometer forest road, and along six thirty-meter stream channel study reaches. A 1.5 m LiDAR DEM was suitable to accurately map the location of the forest road and channel features. Ninety five percent of the LiDAR-derived road length was located within 2.2 m normal to the field-surveyed centerline and LiDAR-derived road slopes were not significantly different from field-surveyed slopes. Stream channel features derived from the LIDAR DEM were located within 2.7 m normal to the field-surveyed thalweg, while the LiDAR-derived slopes measured within 0.49 percent of field-surveyed slopes. These findings indicate that LiDAR can provide accurate terrain measurements that are suitable for resource management and assessment.

Forestry is a large industry in Sweden and methods have been developed to try to optimize the processes in the business. Yet computer vision has not been used to a large extent despite other industries using computer vision with success. Computer vision is a sub area of machine learning and has become popular thanks to advancements in the field of machine learning. This project plans to  investigate how some of the architectures used in computer vision perform when applied in the context of forestry. In this project four architectures were selected that have previously proven to perform well on a general dataset. These four architectures were configured to continue to train on trees and other objects in the forest. The trained architectures were tested by measuring frames per second (FPS) when performing object detection on a video and mean average precision (mAP) which is a measure of how well a trained architecture detects objects. The fastest one was an architecture using a Single Shot Detector together with MobileNet v2 as a base network achieving 29 FPS. The one with the best accuracy was using Faster R-CNN and Inception Resnet as a base network achieving 0.119 mAP on the test set. The overall bad mAP for the trained architectures resulted in that none of the architectures were considered to be useful in a real world scenario as is. Suggestions on how to improve the mAP is focused on improvements on the dataset.

Streszczenie:
High-severity disturbances are the primary drivers of Engelmann spruce-subalpine fir ecosystems in the southern Rocky Mountain. Recently, an unprecedented, landscape-wide (at least 250 km2) spruce beetle outbreak killed virtually all the Engelmann spruce on the Markagunt Plateau in southwestern Utah, USA. Results from dendroecological analyses suggested the combination of antecedent disturbance history and drought-driven stand development was responsible for creating suitable host conditions prior to the recent outbreak. Multiple and consistent lines of evidence suggested mixed- and high-severity fires shaped the development of the Markagunt Plateau. Subsequent stand development, influenced by species-specific differential tree-ring response to drought, resulted in the gradual increase of Engelmann spruce dominance across the landscape. Spatiotemporal outbreak dynamics included the early, independent and spatially synchronous building of beetle populations in moist sites with large Engelmann spruce across the landscape. As the outbreak evolved over time, it is likely temperature anomalies accelerated beetle population growth, leading to more rapid spruce mortality. In the wake of the spruce beetle outbreak, results from simulated potential fire behavior suggested there was a reduction in probability of active crown fire for one or two decades on near-pure Engelmann spruce sites after the outbreak. This counterintuitive result suggested extreme fire behavior is not an inevitable consequence of spruce beetle outbreaks. Regardless of the occurrence of fire, forest response is likely to be dominated by advance regeneration in the seedling bank. Furthermore, because spruce was virtually absent from the understory, forest reorganization is likely to be dominated by subalpine fir. In response to recent outbreaks such as the Markagunt Plateau, silviculturists are questioning what they can do to limit the loss from these likely inevitable spruce beetle outbreaks. Concepts of resistance and resilience can be used in planning vegetation management intended to indirectly control beetle populations by manipulating their habitat (vegetation). Resilient landscapes will ideally have spruce age class diversity and size class diversity in spatially discontinuous patches.

Streszczenie:

The southern pine species group is the main softwood resource used in the U.S, and the majority of southern pine is used in lumber production. The use of lumber in structural purpose requires feasible strength and stiffness grading method ensuring characteristics allowable stress values. The stiffness and strength of most of southern pine lumber is assessed using visual grading system. The objective of this study was to evaluate a production weighted sample of 2 × 4, 2 × 6, 2 × 8, and 2 × 10 No. 2 grade southern pine lumber collected across its geographic range. The results of this research show a snapshot of the material commercially sold in the southern U.S. region. Over one third of the specimens contained pith, and had an average mean value of 4.6 for number of rings per inch (RPI) and 43.8% for latewood (LW). The overall specific gravity (SG), modulus of elasticity (MOE) and modulus of rupture (MOR) were 0.54, 10.1 GPa, and 41.7 MPa, respectively. The allowable design bending strength (Fb) for 2 × 4, 2 × 6, 2 × 8, and 2 × 10 was 11.2, 9.2, 8.1, and 7.1 MPa, respectively. Specimens containing no pith, RPI higher or equal then 4.0, and LW higher or equal then 33.0% were greater in MOE and MOR. The effect of grading controlling characteristics of the material was also studied. The presence of knots had the most significant impact on mechanical properties. Specimens with wane and shake had greater SG, MOE, MOR, Fb values than specimens with others grading controlling characteristics. The mean values found for RPI, LW, and SG met the requirements recommended for southern pine No. 2 lumber. The MOE and Fb values found therein met the previous and the new allowable design value. The results of this research can be used to identify and to select the best variables to improve the prediction of bending properties of visually graded lumber.

Streszczenie:
Climate change will increase weather induced risks to forests, and thus effective adaptation measures are needed. In Säätyö project funded by the Ministry of Agriculture and Forestry, we have summarized the data that facilitate adaptation measures, developed weather and climate services that benefit forestry, and mapped what kind of new weather and climate services are needed in forestry. In addition, we have recorded key further development needs to promote adaptation. The Säätyö project developed a service product describing the harvesting conditions of trees based on the soil moisture assessment. The output includes an analysis of the current situation and a 10-day forecast. In the project we also tested the usefulness of long forecasts beyond three months. The weather forecasting service is sidelined and supplemented by another co-operation project between the Finnish Meteorological Institute and Metsäteho called HarvesterSeasons (https://harvesterseasons.com/). The HarvesterSeasons service utilizes long-term forecasts of up to 6 months to assess terrain bearing conditions. A test version of a wind damage risk tool was developed in cooperation with the Department of Forest Sciences of the University of Eastern Finland and the Finnish Meteorological Institute. It can be used to calculate the wind speeds required in a forest area for wind damage (falling trees). It is currently only suitable for researcher use. In the Säätyö project the possibility of locating the most severe wind damage areas immediately after a storm was also tested. The method is based on the spatial interpolation of wind observations. The method was used to analyze storms that caused forest damages in the summer and fall of 2020. The produced maps were considered illustrative and useful to those responsible for compiling the situational picture. The accumulation of snow on tree branches, can be modeled using weather data such as rainfall, temperature, air humidity, and wind speed. In the Säätyö project, the snow damage risk assessment model was further developed in such a way that, in addition to the accumulated snow load amount, the characteristics of the stand and the variations in terrain height were also taken into account. According to the verification performed, the importance of abiotic factors increased under extreme snow load conditions (winter 2017-2018). In ordinary winters, the importance of biotic factors was emphasized. According to the comparison, the actual snow damage could be explained well with the tested model. In the interviews and workshop, the uses of information products, their benefits, the conditions for their introduction and development opportunities were mapped. According to the results, diverse uses and benefits of information products and services were seen. Information products would make it possible to develop proactive forest management, which would reduce the economic costs caused by wind and snow damages. A more up-to-date understanding of harvesting conditions, enabled by information products, would enhance the implementation of harvesting and harvesting operations and the management of timber stocks, as well as reduce terrain, trunk and root damage. According to the study, the introduction of information is particularly affected by the availability of timeliness. Although the interviewees were not currently willing to pay for the information products developed in the project, the interviews highlighted several suggestions for the development of information products, which could make it possible to commercialize them.

Streszczenie:
For school age children on the island of Puerto Rico, the back-to-back hurricane strikes of Irma and Maria were their first experience with the tragedy of hurricanes in Puerto Rico. There is much concern in the general public about the ability of the Puerto Rican forests, like El Yunque, to recover. These concerns reveal common misconceptions about the dynamics of forest ecosystems. The focus of this research is Journey to El Yunque, a middle school curriculum unit that engages students in evidence-based modeling of hurricane disturbance using long-term data about population dynamics after Hurricane Hugo. Research was guided by the following research question: How does engagement in the science of disturbance ecology impact students’ understanding of and appreciation for ecosystems dynamics? Students completed pre and post assessment understanding of ecosystems dynamics and rated the teacher implementation using the Inquiry-Based Science Teaching survey. Based on a paired t-test, students statistically increased their performance from pretest to posttest with an effect size of 0.22. At the teacher level, the Inquiry-Based Instruction score was a statistically significant predictor of the posttest performance. In other words, these results provide evidence that engaging students in the practices of ecology predicted increased understanding of population dynamics.
