“…Their presence, especially CWD, reduces the risk for gravitational hazards playing an active role against rockfalls (Costa et al 2021). Moreover, the retention of residues also helps reduce the risk of erosion, especially on skid trails (Mazri et al 2020).…”

Salvage logging operations often occur after large disturbances and usually leave behind a substantial quantity of residues, which is fundamental for maintaining soil fertility and facilitating ecosystem dynamics. This study aims to estimate the amount of logging residues following salvage operations categorized by two wood harvesting systems: Cut-To-Length (CTL) and Full-Tree System (FT). Logging residues in the harvested areas were sampled using linear transects and the data collected were divided into classes based on diameter. The quantity of residues was estimated using the Brown method for Fine Wood Debris (FWD) and the Van Wagner method for Coarse Wood Debris (CWD). Furthermore, the carbon and nutrient content associated with logging residues were also determined, considering their interaction with the soil organic layer. Overall, a higher quantity of FWD was detected in the sites cleared with the FT system and a higher quantity of CWD in the sites logged with the CTL system. Differences could be observed for all three years and systems considered, but only the third year reported statistically significant results (p<0.01). The soil and residue chemical analysis for carbon and nutrient contents revealed a high amount of carbon stored in a potential layer of 10 cm of soil (up to 85 Mg·C·ha-1), while only up to 15 Mg·C·ha-1 for the woody material.

Dead woody materials are naturally part of the forest ecosystem introduced through the process of tree mortality or intentionally through stand management practices which result in harvesting residues. The management of harvesting residues includes a range of solutions that vary from site to site, from context to context. The purpose of this review is to determine the current state-of-the-art of harvesting residue management treatments at a global scale. Our review indicates that there are few studies that compare residue management and treatment options, considering the variety of impacts and effects that can be generated. This is surprising as residue management affects residue quantity and distribution and is relevant for numerous ecological processes. The retention of fine and coarse residues can generate positive effects and impacts on various aspects of forest ecosystems including (i) biodiversity, by promoting stand regeneration and providing habitats for fauna at different levels; (ii) soil properties, by decreasing the risk of erosion and soil compaction while retaining moisture at ground level; and (iii) soil nutrients, by replenishing C, N, and micronutrient stocks. On the contrary, harvesting residues can provide material for bioenergy production and potentially other fiber industries. The removal of residues can also reduce wildfire risks and dampen insect outbreak dynamics. In this work, we provide a general outline of the role of residues as well as a summary of current management options adopted around the world. The intention of the work is to provide an information base for stakeholders including forest managers and policymakers in identifying and assessing potential alternatives for their current local practices.
