Tropical deforestation is leading to a loss of economically productive timber concessions, as well as areas with important environmental or socio-cultural values. To counteract this threat in Southeast Asia, sustainable forest management (SFM) practices are becoming increasingly important. We assess the tools and guidelines that have been developed to promote SFM and the progress that has been made in Southeast Asia toward better logging practices. We specifically focus on practices relevant to biodiversity issues. Various regional or national mechanisms now inform governments and the timber industry about methods to reduce the impact of production forestry on wildlife and the forest environment. However, so many guidelines have been produced that it has become difficult to judge which ones are most relevant. In addition, most guidelines are phrased in general terms and lack specific recommendations targeted to local conditions. These might be reasons for the generally slow adoption of SFM practices in the region, with only a few countries having incorporated the guidelines into national legislation. Malaysia, Indonesia, and Laos are among the frontrunners in this process. Overall there is progress, especially in the application of certification programs, the planning and management of high conservation value forests, the regulation and control of hunting, and silvicultural management. To reduce further forest loss, there is a need to accelerate the implementation of good forest management practices. We recommend specific roles for governments, the forestry industry, and nongovernmental organizations in further promoting the implementation of SFM practices for biodiversity conservation.

However, trade-offs between management objectives and a lack of consensus on the ecological consequences of salvage logging impair science-based decision making on the management of forests after natural disturbances. We conducted a global meta-analysis of the impacts of salvage logging on regulating ecosystem services and on fuel loads, as a frequent post-disturbance objective is preventing subsequent wildfires that could be fueled by the accumulation of dead trunks and branches. Salvage logging affected ecosystem services in a moderately negative way, regardless of disturbance type and severity, time elapsed since salvage logging, intensity of salvage logging, and the group of regulating ecosystem services being considered. However, prolonging the time between natural disturbance and salvage logging mitigated negative effects on regulating ecosystem services. Salvage logging had no overall effect on surface fuels; rather, different fuel types responded differently depending on the time elapsed since salvage logging. Delaying salvage logging by ~2–4 years may reduce negative ecological impacts without affecting surface fuel loads. ; Project AS2013/MAE-2719 "REMEDINAL-3" from the Government of Madrid
