Effect of size and additives on the decomposition process and nutrient content of urban organic waste compost

To participate in overcoming the problem of 500 tons of organic waste per day in Makassar City, in 2017-2019 Environment and Forestry Research and Development Institute of Macassar conducted research activities to develop community-based organic waste management models for pollution control and urban farming development. One of the activities is making compost from urban litter using a shredding machine to speed up the decomposition process, and mixing household waste rich in N, P, K and micro nutrients to increase the nutrient content of the compost. Observations showed that the litter mincing process significantly accelerated the decomposition process. Furthermore, the addition of nutrient-rich material from household waste into compost material has increased the nutrient content of compost which is higher than the SNI standard, thereby increasing the competitive value of compost against factory-made chemical fertilizers. These two activities have an impact on increasing public interest in managing urban organic waste to reduce pollution while developing urban farming.

Effect of training and development on employees' performance at forestry research institute of Nigeria

Training and development are the major determinants of employees’ job performance which could lead to intentions to quit, absenteeism, low commitment, and productivity in the workplace. The study assessed and tested the impact of training and development on employees’ performance at the Forestry Research Institute of Nigeria, Ibadan, Oyo State, Nigeria. The data collected was primary and cross-sectional. A multi-stage sampling technique was used in selecting 226 respondents in the study organization. The results revealed that the mean age of the employees was 40 years while their average annual income was ₦ 1,272,600 and years of work experience was 9.16 years. The descriptive results showed that the perceived benefits of employees’ training and development in the Forestry Research Institute of Nigeria are high (5.28). The perceived enhanced employees’ competency levels through the training and development in the Forestry Research Institute of Nigeria are high (5.09). The employees’ perceived contributions of training and development to their job performance in the Forestry Research Institute of Nigeria is high (5.44) while the employees are high job performers (6.03). The regression results indicated that there was a significant relationship between employees’ job performance and the benefits of employees’ training and development (β = 0.59; p<0.05), enhanced employees’ competency levels through the training and development (β = 0.68; p<0.05) and employees’ perceived contributions of training and development to job performance respectively (β = 0.741; p<0.05). The study concluded that the training and development positively impacted employees’ performance in the Forestry Research Institute of Nigeria, Ibadan, Oyo State, Nigeria. It was recommended that the organization’s management team should reconsider funding and instituting proper training and development programs.

Influence of leadership approaches on workforce performance at forestry research institute of Nigeria

The study examined the influence of leadership approaches on workforce performance at the Forestry Research Institute of Nigeria. A multi-staged procedure was used in selecting 160 workforces in the organization. Descriptive statistics and Pearson product-moment correlation coefficient were used in analysing the data collected. Results showed that the exhibited organizational leadership approaches were democratic (5.08), transformational (4.73), autocratic (4.41) and laisse-faire (3.87) while the workforces in the organization had a very good level of workforce performance (5.62). The organizational leadership approaches exhibited (r = 0.34; p≤0.05) had a positive and significant relationship with workforce performance. The study concluded that the management of the institution endeavour to stimulate the exhibition of these leadership approaches to enhance the managerial influences, workforce performance and the achieving organizational objectives success.

Optimizing Observation Plans for Identifying Faxon Fir (Abies fargesii var. Faxoniana) Using Monthly Unmanned Aerial Vehicle Imagery

Faxon fir (Abies fargesii var. faxoniana), as a dominant tree species in the subalpine coniferous forest of Southwest China, has strict requirements regarding the temperature and humidity of the growing environment. Therefore, the dynamic and continuous monitoring of Faxon fir distribution is very important to protect this highly sensitive ecological environment. Here, we combined unmanned aerial vehicle (UAV) imagery and convolutional neural networks (CNNs) to identify Faxon fir and explored the identification capabilities of multispectral (five bands) and red-green-blue (RGB) imagery under different months. For a case study area in Wanglang Nature Reserve, Southwest China, we acquired monthly RGB and multispectral images on six occasions over the growing season. We found that the accuracy of RGB imagery varied considerably (the highest intersection over union (IoU), 83.72%, was in April and the lowest, 76.81%, was in June), while the accuracy of multispectral imagery was consistently high (IoU > 81%). In April and October, the accuracy of the RGB imagery was slightly higher than that of multispectral imagery, but for the other months, multispectral imagery was more accurate (IoU was nearly 6% higher than those of the RGB imagery for June). Adding vegetation indices (VIs) improved the accuracy of the RGB models during summer, but there was still a gap to the multispectral model. Hence, our results indicate that the optimized time of the year for identifying Faxon fir using UAV imagery is during the peak of the growing season when using a multispectral imagery. During the non-growing season, RGB imagery was no worse or even slightly better than multispectral imagery for Faxon fir identification. Our study can provide guidance for optimizing observation plans regarding data collection time and UAV loads and could further help enhance the utility of UAVs in forestry and ecological research.

Fishing techniques used for the exploitation of fish in the flooded swamp forest of the Lake Tumba micro-basin on the Mbandaka-Center for Research in Ecology and Forestry (CREF Mabali) road axis in Bikoro in the Equateur Province (R.D Congo)

The objective of this study was to inventory the different fishing techniques used for the exploitation of fish in the flooded swamp forest of the Lake Tumba micro-basin on the Mbandaka-Center for Research in Ecology and Forestry (CREF Mabali) road axis in Bikoro in the Equateur Province of the Democratic Republic of Congo. The exchange-based surveys were carried out using a pre-established survey form to exchange with the fishermen working in the different study sites in order to obtain the expected data. The harvesting of fish was done in a traditional manner using the different fishing gears and techniques used by the fishermen in the study area. The results obtained show that the majority of the fishing practices implemented in this area are not sustainable. In total, ten (10) fishing techniques were identified, among which five (5) easily provide fish, namely, creel fishing, scooping, fishing with ichthyotoxic plants, longline fishing and line fishing, which are the most used by the fishermen. Four fishing techniques (fishing with traditional traps, scooping, fishing with ichthyotoxic plants and fishing by weeding the areas) were considered non-selective and capable of creating an imbalance in the different aquatic ecosystems surveyed. This study contributes to the improvement of the knowledge on the exploitation of the animal biodiversity of the Democratic Republic of Congo, on the one hand, and on the other hand, the perpetuation of the knowledge of the local population whose obsolete character is not in doubt.Keywords: Bikoro; Fishing gear; Fishing techniques; Ichthyological fauna; R.D Congo

Phytochemical, Antioxidant, Cytotoxicity and Antimicrobial Investigations of Tephrosia platycarpa GUILL. & PERR.

Tephrosia genus belongs to the family Fabaceae and plants in this genus have been reported to possess antimicrobial, anti-inflammatory and pesticidal properties, however; there is paucity of information on the chemical and biological activities of Tephrosia platycarpa. Thus, this study was aimed at investigating the phytochemical and biological properties of Tephrosia platycarpa. The plant was collected at Ile’gbon, Ibadan, Nigeria and authenticated at Forestry Research Institute of Nigeria (FHI-112653), air-dried and pulverized. Extracted with n-hexane, ethyl acetate and methanol successively. The extracts were screened for phytochemicals, antioxidant, cytotoxicity and antimicrobial activities. Phytochemical screening of the crude extracts showed that they are rich in secondary metabolites. The antioxidant assay showed that extracts of the stems and leaves have strong activities against free radicals. Cytotoxicity assay revealed that the extracts of the stem are moderately toxic while roots extracts are highly toxic. The extracts displayed broad spectrum antimicrobial activity against the organisms tested.

Leadership Styles and Employees’ Job Performance at Forestry Research Institute of Nigeria

The study examined leadership styles and employees’ job performance in the Forestry Research Institute of Nigeria (FRIN). A total of 120 employees were chosen at random from among the 900 FRIN employees. Percentages, means, standard deviation and regression were used for the analysis. Results showed that the majority (89.2%) of the employees displayed transformational leadership styles while 87.5% of the employees were democratic in their leadership styles. Indicators of autocratic leadership style include: superiors telling subordinates what to do, how to do it, and when they want it done (x̄ =3.6). Indicators of laissez-faire leadership style include employees responsible for defining his or her own job ( x̄ = 3.01). Aspects of job performance influenced by the leadership styles of employees include: efficiently managing information and data ( x̄ = 4.10) and achieving deadlines ( x̄ = 4.10). Transformational (78.5%) and democratic styles (54.3%) caused (variations in employee job performance. The organization made used of transformational and democratic leadership styles more than other leadership styles. The organisation should encourage the use of the two styles and mix it with other leadership styles where necessary in order to improve the administrative strength and achievement of organisational goals

Increased dimensional stability of Eucalyptus grandis × Eucalyptus urophylla ‘GLGU9’ wood through palm oil thermal treatment

Eucalyptus grandis × Eucalyptus urophylla ‘GLGU9’ is one of the most commonly planted tree species in South China. It is a new variety created by Guangxi Zhuang Autonomous Region Forestry Research Institute. As a fast-growing species, the poor dimensional stability is one of its main drawbacks, which restricts its applications. Thermal treatment is one of the effective methods to improve the dimensional stability of wood. GLGU9 wood was treated using thermal modification with palm oil. The oil was used as a heating medium and a shielding material at temperatures of 150, 170, 190, 200, and 210 °C, at various treatment durations of 1.5, 3, 4.5 and 6 h. To investigate the effect of palm oil thermal treatment on dimensional stability, the anti-shrink efficiency (ASE1) and anti-swelling efficiency (ASE2) were examined. The results indicated that the ASE1 and ASE2 were increased by 62.8% and 56.6% at 210 °C for 6 h treatment, respectively.

Bibliometric Analysis of Forestry Research in Mexico Published by Mexican Journals

There is scarce research assessing the productivity of scientific articles on forestry topics. The objective of this study was to analyze the scientific production on forestry topics that originated in Mexico and were published in Mexican journals from 1996 to 2019 and to identify the causes that determine the impact factor of such publications and the space-time evolution of forestry research in Mexico. In addition, to analyze whether researchers tend to publish in journals published by their affiliation institutions. The study considered 2384 scientific articles from seven journals belonging to category VI of Biotechnology and Agricultural Sciences listed in the Journals Classification System by the National Council of Science and Technology that publishes forestry topics. Bibliometric indicators were generated through text mining and analysis of co-authorship networks. It was found that forestry research in Mexico from 1996 to 2019 presented exponential growth in the number of publications. Forestry scientific production was concentrated in the center of the country. It was dominated by researchers from three of 122 institutions: Instituto Nacional de Investigaciones Forestales, Agrícolas y Pecuarias (13.88%), Colegio de Postgraduados (12.50%), and Universidad Autonoma Chapingo (10.44%). The journals with the highest number of publications were: Revista Mexicana de Ciencias Forestales (26.51%), Revista Chapingo Serie Ciencias Forestales y del Ambiente (20.34%), and Madera y Bosques (18.88%). Results show that forestry researchers in Mexico published mostly in journals edited by their affiliation institutions, which restricts constructive criticism of peer review and increases academic endogamy. Also showed the need to generate more forestry research for the southeast of the country on topics such as climate change, carbon capture, forest biometry, and remote perception, which are relevant aspects when we consider that no published research evaluated the development of the forestry sector in Mexico.

Hierarchical Task Analysis (HTA) for Application Research on Operator Work Practices and the Design of Training and Support Systems for Forestry Harvester

Highly mechanized forestry operations are essential for efficient timber harvesting. Therefore, the skills of harvester operators appear to be key to productive and sustainable use of the machines. Recent research has revealed a knowledge deficit regarding the work practices of forest machine operators. This urges systematic research into forestry machine handling and a corresponding refinement of analytical methods. Current analyses of operator tasks in forestry are less formalized and focus predominantly on machine efficiency and overall performance, but not so much on the human-related conditions of work performance and workload. Therefore, the objective of this paper is to introduce hierarchical task analysis (HTA) into forestry science. HTA is a versatile, formalized human-factors method that can be used to describe the work objectives of forest machine operators. HTA is suitable, for example, for describing (in)efficient work practices and thus as a basis for designing machine operator training and for systematically evaluating assistive technologies. The task analyses in this paper draw on a recently published empirical approach to analyzing work practices, workflows, and machine operator behavior for optimal human–machine collaboration in forestry application research. Specifically, the main work methods of clearcutting and thinning stand in European forestry were considered, with examples from Scandinavian and German method application. The process of HTA is described and a prototypical approach to HTA for both working methods provided. As a result, this work could show that a single work practice affects operator goals within different work elements and sets out how inefficient work practices can be described in terms of operator goals. With the introduction and exemplary application of HTA, a structured task definition in human-centered approaches is encouraged to analyze work practices, workflows, and machine operator behavior for optimal human–machine collaboration in forestry application research.

Working Posture and the Center of Mass Assessment While Starting a Chainsaw: A Case Study among Forestry Workers in Croatia

Motor-manual work with a chainsaw is still an irreplaceable occupational activity in forest harvesting operations in Croatia and in many other countries. Chainsaw workers are exposed to different risk factors, such as noise and vibrations, heavy load lifting, awkward and preflexion postures, repetitive movements, etc. The working posture and the assessment of the center of mass plays an important role in understanding the exposure of forest workers to postural and occupational risks, either as a part of the entire work process or as a part of an individual element of the work technique. Therefore, the aim of this research was to investigate the impact of three different chainsaw starting methods (from the ground, between the knees, and “drop starting”) on the postural load of the chainsaw worker and its association with personal and occupational factors. The field portion of data collection was conducted in the second and third quarters of 2022. For trunk posture assessment (n = 74), the rapid entire body assessment (REBA) tool was used, and for the center of mass measurement (n = 28), the Xsens MVN Link motion capture suit was used, a relatively new technology that allows data collection in real field conditions. Descriptive and inferential statistical methods were used to verify and analyze the field data. Based on the obtained results, almost 50% of the sampled chainsaw workers ignored safety instructions and preferred “drop starting” a chainsaw. The results also showed that there is a significant difference between the three starting methods in the REBA score, as well as in the number of segments scored during the assessment. The obtained mean REBA score for all three methods is between 4 and 7, placing all methods at a medium level of MSD risk. Regarding the analysis of the Center of Mass (CoM) vertical deviation, the statistical difference is noticeable for the body mass index (BMI) group, the group related to experience with the chainsaw, and the age and height group in relation to three methods for starting a chainsaw. The safest method, which implies starting a chainsaw from the ground, resulted also as the riskiest in terms of postural strain, which, cumulatively over the time variable, can contribute to health problems in forest workers. In conclusion, related to the future process of professional training development for chainsaw workers, an integral part of the training must contain the most optimal postural-movement habits that need to be defined by further kinematic research in forestry.

UAV data collection parameters impact on accuracy of Scots pine stand mensuration

A wide range of UAV systems used for forest research requires unified approaches to data collection. The research aims to determine the optimal parameters for UAV data collection to obtain accurate information about stands, considering the cost of resources for its collection. The process of collecting remote sensing data consisted of nine combinations divided into three levels of overlap and three levels of spatial resolution (survey altitude) and changing the degree of filtering of a dense point cloud during image processing. Individual tree detectingin the stand was performed using the R programming language and the ForestTools package. The results of the assessment of the dependence of the radius of tree crowns on their height were used to set the parameters of the variable filter function for finding local maxima for Scots pine stands. Errors in the identification of treetops were estimated using the F-score. The identified heights were compared with the field data of the ground survey. The proportion of classified digital elevation model DEM in the dense point cloud was reduced from the total area of the test site using images of 4.1 cm/pix spatial resolution (150 m survey altitude). The study presents the results of assessing the impact of spatial resolution of optical images collected from UAVs and their overlap on the results of measurements of stands parameters. It is determined that a photogrammetric survey with input images with a longitudinal overlap of less than 90% is not appropriate for the study of forest areas due to the impossibility of aligning all images. The results of the assessment of tree accounting in the stand showed that it is most appropriate to use images with a spatial resolution of up to 3.3 cm/pix (120 m survey altitude), otherwise, the proportion of missed treetops increases. Reducing the spatial resolution of remote sensing data leads to an increase in errors in determining the height of individual trees, and the average heights of the experimental plots had the same trend. Given the combination of the assessed factors, it is not recommended to use images with a spatial resolution of more than 3.3 cm/pix for forestry research due to increased errors in the individual tree detection and tree height determination. The results obtained can be used to select data collection parameters for research on Scots pine stands to assess their growing stock and phytomass

Perceptions of uncertainty in forest planning: contrasting forest professionals’ perspectives with the latest research

Many of the intrinsic facets of forest planning are surrounded by uncertainty. Decision-makers strive to improve their understanding of the sources of uncertainty and their impact on the decision-making process. However, uncertainty is rarely integrated into real-world forestry applications or into decision support tools used in forest planning problems. To identify the needs, interests, and challenges of managing uncertainty in forest planning, we interviewed forestry professionals. All the interviewees indicated the positive potential of a tool that could address some facets of uncertainty. Additionally, we conducted a review of the most recent literature on this topic to understand current hot topics and future trends that could help address real-world challenges. This study highlights the next steps to incorporate uncertainty into the decision support systems for forest planning. However, to strengthen the bond between the practical needs of forestry professionals and the theoretical approaches proposed by recent literature, more effort should be placed on defining terminology and formulating a theoretical framework for uncertainty analysis. This will provide the forestry community with a common language and typology, help increase its general understanding, and improve communication between forestry researchers, forestry professionals, and other stakeholders.

Genotypic variation in water relations and gas exchange of urban trees in Detroit, Michigan, USA

Increasing tree species diversity has become a key underpinning for communities to improve resilience of urban and community forests. Increasingly, urban forestry researchers are examining physiological traits to aid in selecting trees for urban sites. Knowledge of physiological responses also has implications for understanding species’ resilience to increased stresses associated with climate change. Here, we compare growth, leaf SPAD chlorophyll index, water relations, and gas exchange of seven genotypes of shade trees planted in two locations in downtown Detroit, MI, USA. Genotypes included Redpointe® maple (Acer rubrum ‘Frank Jr.’), Flashfire® maple (Acer saccharum ‘JFS-Caddo2′), Pacific Sunset® maple (Acer truncatum x platanoides ‘Warrenred’), Emerald City® tulip tree (Liriodendron tulipifera ‘JFS-Oz’), Chanticleer® pear (Pyrus calleryana ‘Glen’s Form’), swamp white oak (Quercus bicolor), and Emerald Sunshine® elm (Ulmus propinqua ‘JFS-Bieberich’). Trees were planted in either Lafayette Plaisance Park (Park), a large urban greenspace, or on the median of St. Aubin Avenue (Median), a nearby major thoroughfare. Tree height growth and leaf SPAD index were higher for trees planted in the Park location than on the Median. However, genotypic variation was larger than the effects of location or the interaction of Genotype × Location for most traits. Across measurement dates, midday leaf water potential was lowest for Pyrus trees and highest for Ulmus and Liriodendron trees. Pyrus and Quercus trees had relatively high rates of net photosynthesis (A) and stomatal conductance (gs) while Liriodendron, Acer saccharum, and Ulmus trees had low rates of A and gs. Liriodendron trees closed their stomata rapidly as leaf water potential (Ψw) declined (isohydric response), while Pyrus and Quercus trees maintained gs across a range of leaf Ψw (anisohydric response). Liriodendron trees also had the highest relative growth rates, suggesting that drought stress avoidance through isohydry is a viable drought tolerance mechanism in urban trees.

Plant in situ tissue regeneration: dynamics, mechanisms and implications for forestry research.

Plants possess remarkable developmental plasticity and regenerative ability to reshape themselves in response to external stimulations. After localised injuries, they can initiate cellular reprogramming at the wound sites to repair or regrow structures that could substitute the functionality of the damaged or lost parts. This way of regeneration in plants is called plant in situ tissue regeneration. Upon wounding like excision, incision or girdling, the original tissue patterns are completely or partially destroyed, the remanent tissues could perceive the wounding signals and thereby initiate cell de-differentiation, trans-differentiation or re-differentiation to reconstruct the lost or damaged tissues. In this review, we summarize the regenerative dynamics and regulatory mechanisms during the major in situ tissue regeneration processes in plants, including secondary vascular tissue (SVT) regeneration after girdling, apex regeneration after excision and tissue reunion after incision. In addition, we compare the features of SVT regeneration, the most relevant system for forestry, with other plant in situ tissue regeneration systems. We further discuss the unsolved issues and the potential applications of plant in situ regeneration for forestry research, aiming to provide new insights for the study of woody plant development.
