| Key Forestry Practices |
Typical definition and some examples |
Effect on greenhouse gases |
| Afforestation |
Tree planting on lands previously not in forestry (e.g., conversion of marginal cropland to trees). | Increases carbon storage through sequestration. |
| Reforestation |
Tree planting on lands that in the more recent past were in forestry, excluding the planting of trees immediately after harvest (e.g., restoring trees on severely burned lands that will demonstrably not regenerate without intervention). | Increases carbon storage through sequestration. |
| Forest preservation or avoided deforestation |
Protection of forests that are threatened by logging or clearing. | Avoids CO2 emissions via conservation of existing carbon stocks. |
| Forest management |
Modification to forestry practices that produce wood products to enhance sequestration over time (e.g., lengthening the harvest-regeneration cycle, adopting low-impact logging). | Increases carbon storage by sequestration and may also avoid CO2 emissions by altering management. May generate some N2O emissions due to fertilization practices. |
