Abstract

Abstract 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.
