“…However, the biomass carbon sink is also relevant, as has been evidenced in studies conducted in the Mediterranean region (e.g., Montero et al, 2004;Cañellas et al, 2008;Cotillas et al, 2016). Hence, in the Mediterranean area, coppice management for biomass production using medium rotation periods could also provide an important source of raw material for bioenergy purposes, providing an alternative to fossil fuels and therefore reducing the emissions associated with the latter (Cañellas et al, 2004;Laina et al, 2013;Spinelli et al, 2014).…”

Aim of study: TTo review and acknowledge the value of carbon sequestration by forest management in the Mediterranean area. Material and methods:We review the main effects of forest management by comparing the effects of silvicultural systems (even-aged vs. uneven-aged stands, coppice systems, agroforestry systems), silvicultural options (thinning, rotation period, species composition), afforestation, harvesting, fire impact or effects of shrub layer on carbon sequestration in the Mediterranean area.Main results: We illustrate as forest management can clearly improve forest carbon sequestration amounts. We conclude that forest management is an effective way to maintain and enhance high carbon sequestration rates in order to cope with climate change and provision of ecosystem services. We also think that although much effort has been put into this topic research, there are still certain gaps that must be dealt with to increase our scientific knowledge and in turn transfer this knowledge to forest practitioners in order to achieve sustainable management aimed at mitigating climate change.Research highlights: It is important to underline the importance of forests in the carbon cycle as this role can be enhanced by forest managers through sustainable forest management. The effects of different management options or disturbances can be critical as regards mitigating climate change. Understanding the effects of forest management is even more important in the Mediterranean area, given that the current high climatic variability together with historical human exploitation and disturbance events make this area more vulnerable to the effects of climate change.Additional keywords: global carbon cycle; forest sink; forest mitigation strategies; carbon sequestration potential; climate change mitigation; Mediterranean forests.

“…However, conversion has met with partial success in Southern Europe and in the Balkans, due to the stronger survival of a rural economy and the specific ecological conditions [3]. Regardless of silvicultural strategy, coppice forests have been often neglected in recent times, due to a number of factors, and especially the rural migration to the cities and the introduction of fossil fuels [4].…”

“…Plantations of eucalyptus in Central-West Portugal have been identified as one of the most intensively managed forested areas in Europe [63]. Large plantations have also been established in Spain following the decision to increase the share of energy from woody biomass to the national energy mix [64].…”

“…Three harvesting systems were examined in a total of 11 sites in Q. pyrenaica Willd. coppice stands in Spain [64]. The harvesting systems included the following: 1) a mechanised whole tree system (WTS), which included chipping at the landing; 2) a fully mechanised CTL harvesting system for firewood; and 3) a semi-mechanised CTL system with manual felling and bunching.…”

Mechanised Harvesting of Broadleaved Tree Species in Europe

Purpose of the Review The application of cut-to-length (CTL) technology for harvesting and processing timber from broadleaved tree species is a challenging process, due to thick branches, stem sweep, forks and high wood density. The objective of this review was to describe the current state of harvester use and characterise the effectiveness of mechanised forest operations for broadleaved and mixed forest stands in Europe, paying particular attention to productivity and product quality aspects. An additional aim was to identify the greatest difficulties associated with harvesting broadleaved tree species today and to indicate future challenges and areas for improvement. Recent Findings An interest in wider harvester use for broadleaved tree species started after the storm Lothar in France in 1999. Early experiences demonstrated that lower productivity is common when harvesting broadleaved tree species, due to limitations in delimbing and the high frequency of sweep. Initially, modifications were made to harvester heads, while a newly designed head (CTL 40 HW) was later developed within a European project in 2005–2007. Using various heads, very high productivity was achieved in some cases, but log recovery was unsatisfactory, with large tree tops left without delimbing. The delimbing was of lower quality and log length inaccuracy was observed, as well as economic losses due to damage to plywood caused by feed rollers. These issues resulted in a change in harvester head construction, including work on a patent for a head designed specifically for harvesting broadleaved tree species. Summary The harvester heads that have been developed to date for broadleaved tree species have mainly been used within Central Europe, where the high incidence of broadleaved tree species and their particular morphological features (thick branches and sweep) are a major challenge for CTL technology. There have been many research projects related to this issue: in the last 15 years, there were a few larger initiatives leading to the design and development of harvester heads for broadleaved tree species, with participation from institutions and universities in France, Germany and Poland. There are currently no ongoing initiatives, but the formation of new ones is strongly recommended because today’s forests have a growing share of broadleaved tree species and are being managed to an increasing extent with CTL technology.
