3. Release Operations
Designed to free young trees from undesirable, usually overtopping, competing vegetation, conducted early on in stand development; by definition, while the stand is in the sapling size class or earlier.
Weeding
Cleaning
Liberation

4. Intermediate Treatments

5. Intermediate Treatments - Thinning
Thinning is treatment to increase the diameter increment of residual trees, improve stand quality and health, and increase stand level production by cutting excess and potential mortality trees without permanently breaking the crown canopy.
Low thinning
Crown thinning
Selection thinning
Geometric thinning
Free thinning

6. Intermediate Treatments – Improvement Cutting
A cutting in stand past sapling stage in order to improve composition, growth, and quality by removing less desirable trees of any species from the canopy

7. Intermediate Treatments – Sanitation Cutting
The removal of vegetation to prevent actual or anticipated spread of insects or disease; often combined with other types of harvest.

8. Intermediate Treatments – Salvage Cutting
The removal of dead trees or trees being damaged or killed by injurious agents other than competition (e.g., insects, disease, fire, wind), in order to obtain monetary value that would otherwise be lost

9. Intermediate Treatments – Prescribed Fire
The intentional application of fire to reduce fuel, competition, insects and disease, improve wildlife habitat, and/or aesthetics

10. Intermediate Treatments – Tree Pruning
Loss or removal of tree branches, by natural or artificial means

11. Forest Fertilization
Addition of nutrient amendments to forest stands to increase tree and stand production

12. Regeneration Methods

16. Site Preparation

17. Site Preparation
Purposeful treatment of the site to prepare for the regeneration process before/immediately following harvest.
Any treatment that modifies vegetative or physical site conditions to improve germination, survival, subsequent growth, or planting of desired seedlings
