“…The height of seedlings was also found to be lower on machine operating trails than in undisturbed areas [63]. The effects of soil compaction may create particularly challenging conditions for seedling survival during drought periods, because seedlings with short roots may be unable to access water at deeper soil levels [44,55].…”

“…The amount of damage to regeneration can decrease when workers have more experience [61•]. Soil scarification can increase the success of natural regeneration [10], but at the same time soil compaction may reduce the establishment of regeneration [44] and growth of regeneration [23]. Compacted soil layers due to forest machine traffic are the most common problem affecting seedling regeneration after forest harvesting [23,432,44].…”

Purpose of Review Lowering the impact of forest utilisation on the forest environment is a part of the improvement in sustainable forest management. As part of forest utilisation, timber harvesting can also cause environmental implications. The main impact of forest operations is on the soil, on regeneration and on the residual stand. The aim of the present review was to identify the state of the art in forest utilisation, identifying how and how much forest operations affect forest soil, regeneration and the remaining stand. Particular attention was paid to the level of impact and potential to limit this. Recent Findings There are a large number of publications tackling forest harvesting, but most of them do not give a comprehensive framework and they mainly focus on one or very few aspects of forest damage. In order to improve general knowledge of the impact of forest operations, it was proposed that the scope of recent findings should be examined and a compilation of the available results from different regions should be presented in one paper. Summary It was found that the least impactful machine-based forest operations were harvester-forwarder technologies, while a larger scale of damage could be expected from ground-based extraction systems (skidders) and cable yarders. Animal power, if applicable, tended to be very neutral to the forest environment. A decrease in damage is possible by optimising skid trail and strip road planning, careful completion of forest operations and training for operators. The existence of legal documents controlling post-harvesting stand damage are rare and have been implemented in only two countries; there is no post-harvesting control on soil damage and natural regeneration.

“…Instead, felling of trees is done exclusively with chainsaw and timber is extracted to roadside landings by animals (e.g. mules) or with rubber-tired skidders, crawler tractors and modified agricultural tractors (Naghdi et al 2016).…”

Masumian A., Naghdi R., Zenner E.K., Nikooy M., Lotfalian M. (2017): Comparison of different erosion control techniques in the Hyrcanian forest in northern Iran. J. For. Sci., 63: 549-554.The aim of this study was to evaluate the effects of closure best management practices (BMPs) on runoff volume and soil loss on skid trails that received two densities of soil cover mats and were located on two slope gradients in an Iranian temperate mountainous forest. The treatments included combinations of three closure BMPs (water bar only, water bar + sawdust, and water bar + hardwood slash), two amounts (densities) of mats (7.5 and 15 kg·m -2 ), and two levels of slope gradients (≤ 20% and > 20%). Results showed that the water bar treatment was the least effective erosion control treatment, followed by the hardwood slash and sawdust treatments. Averaged over mat densities and both slope gradients, the average runoff rates and amounts of soil loss from the skid trails with the water bar treatment were 46.7 l per plot and 6.1 g·m -2 , respectively, 16.8 l per plot, 2.8 g·m -2 , respectively, with the hardwood slash treatment and 11.7 l per plot, 1.9 g·m -2 , respectively, with the sawdust treatment. The results indicated that surface cover is a necessary element for controlling erosion losses following a skidding disturbance, particularly on steep slopes.
