Forests are sensitive to the effects of climate change and play a significant role in carbon cycles. This duality has important implications for forest management in terms of requirements for enhanced and integrated adaptation and mitigation interventions. Two ideal conceptual level changes could provide the means for implementation. First, the incorporation of climate change considerations into definitions of sustainable forest management (SFM) would provide mandates for enhanced approaches. Second, the mainstreaming of enhanced SFM would facilitate implementation. There are, however, factors that may impede implementation. Identifying and evaluating these factors informs our understanding of requirements for adaptation and mitigation mainstreaming. This study reviews, organizes, and interprets the literature for the purposes of identifying and evaluating potential impediments. Harmonization barriers pertain to differences between adaptation and mitigation in pre-existing frames and beliefs. Enabling barriers are psychological and institutional in nature. Implementation barriers include capacity deficits (e.g., funding limits, science and knowledge deficits regarding benefits, trade-offs, and synergies between adaptation and mitigation) and governance issues. Barriers are interrelated, dynamic, and subjective. Addressing barriers requires a holistic approach that recognizes the complex and dynamic nature of forest management policy change processes.
