“…Later on, Carll (2009) added data for Hawaii, where the SCI was > 300. Numerous authors used the SCI for decay hazard mapping of various countries and regions such as Canada (Setliff 1986), North America (Morris et al 2008), Korea (Kim et al 2011;Kim and Ra 2014), Iran (Helali et al 2021), China (Wang et al 2007), Japan (Hasegawa 1996), Australia (Wang et al 2008a), Switzerland (Brischke and Selter 2020), Norway (Lisø et al 2006;Tajet and Hygen 2017), United Kingdom (Curling and Ormondroyd 2018), Spain (Fernandez-Golfin et al 2016), Greece (Nikolitsa and Giarma 2019), Northern Europe (Niklewski et al 2016b), Slovenia (Humar et al 2021) and Europe (Brischke et al 2011;.…”

Mapping the biotic degradation hazard of wood in Europe – biophysical background, engineering applications, and climate change-induced prospects

Construction using timber has seen a resurgence in light of global climate mitigation policies. Wood is a renewable resource, and engineered wood products are proving to be competitive against concrete and steel while having several advantages. However, while the renewable nature of wood in construction is a beneficial property for climate mitigation policies, the process of biodegradation introduces a challenge for service life planning. A review of hazard mapping is presented while developing contemporary hazard maps, occurrence maps and projected hazard maps for 2050 using representative concentration pathways (RCP) 2.6 and 8.5. The risk of timber decay is expected to increase in most of Europe as the temperatures rise, with a decrease expected in dryer regions. Termites are likely to experience a range expansion as more areas become suitable, while human activity and an increase in extreme weather events like floods are expected to facilitate dispersion. Marine borer species already present a risk in most European coastal regions; however, the effect of changes in water temperatures are likely to shift the boundaries for individual borer species. Overall, warmer climates are expected to increase the metabolic activity of all of these organisms leading to a general reduction in service life.

“…This indicates that LRM has sufficient retention rate at higher BA concentrations to protect against attacks from insects and fungi especially since LRM is highly susceptible to lyctic borers and termites (Wood Solutions, 2024). For reference, a weight loss of 5%-10% will result in a decrease of mechanical properties from 20% to 80% (Kim et al, 1996). The retention rate of wood is a function of SAV ratio as higher SAV will result in higher retention rates and vice versa.…”

This study investigates the influence of varying concentrations of boric acid (BA) preservative on the physical and mechanical properties of light red meranti (LRM) found in Sarawak. LRM or Shorea leprosula samples were treated with various concentrations of BA via the dip diffusion method using American Society for Testing and Materials (ASTM) standards. The physical property, particularly the retention rate and mechanical properties, bending strength, modulus of elasticity (MOE), tensile and compression strength parallel to grain of impregnated and control samples were tested to determine the effects of BA preservative. The retention rate was found to increase with increasing BA concentration and higher surface area to volume ratio. The mechanical properties in terms of the MOE and tensile strength parallel to grain were found to be greater than those of the control samples, whereas the bending strength and tensile strength parallel to grain were lower. Amongst the results, only the retention rate and MOE showed significant interaction effects at 5% level of significance between all factors tested (samples size and BA concentration for retention rate and BA concentration for MOE).

“…At the same time, the forest area is a dynamically changing environment. The constantly changing environmental conditions also influence the efficiency of the logging process (Kim and Ra, 2014;Ra, 2017;. Thus, there is a need to develop theoretical research precisely taking into account the dynamics of environmental change.…”

Using forest resources involves solving complex and diverse tasks. At the same time, one of the key goals in the field is improving the quality of forest infrastructure. This direction requires adequate mathematical and economic justification. Moreover, creating an effective infrastructure will not only increase the accessibility and usage volumes of wood and other forest resources, but also contribute to the development of continuous and sustainable forest management. The existing practice of making decisions in terms of the organizational and technological aspects of logging, based on the personal experiences of managers or leading specialists in enterprises, hinders the achievement of constant optimal efficiency. The paper presents results that are a continuation of the research cycle of the authors' team in the fields of optimization and algorithmization of various logging processes. The focus of the study lies in the processing and movement of wood resources, the most valuable products of the investigated groups of enterprises. To this end, the paper presents a developed algorithm for determining an effective technological chain of transportation in logging operations, and for improving loading and unloading processing operations under dynamic natural and production conditions. This algorithm serves as the methodological basis for designing logging infrastructure in a dynamically changing environment.
