FOR 350 Silvicultural Terminology Review

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

Intermediate Treatments

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

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

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.

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

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

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

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

Regeneration Methods

Regeneration Methods Even-aged Clearcutting Seed tree Shelterwood

Regeneration Methods Uneven-aged Single tree selection Group selection

Regeneration Methods Two-aged Irregular or reserve shelterwood Deferment cut

Site Preparation

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

Site Preparation - Mechanical Manual felling Manual girdling Shearing Drum chopping Rake-and-pile Mastication Disking Bedding Subsoiling

Site Preparation - Chemical Broadcast Spot or strip Individual stem

Site Preparation – Prescribed Fire The intentional use of fire to: Reduce slash and fuels Kill interfering vegetation Alter forest floor characteristics Sustain fire dependant communities
