If carbon stocks and fluxes in temperate and boreal forests are to be included among efforts to mitigate global climate change, forest managers and policy makers must understand how management affects the carbon budgets in these systems. This chapter examines the effects of management of carbon sequestration, storage, and flux in temperate and boreal forests. Particular silvicultural points considered are drained wetlands, thinning, extending rotation lengths, and fertilization. Management considerations discussed included leakage, additionality, defining baselines and emissions from management operations.
