FOR 350 Silvicultural Terminology Review
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
13
Regeneration Methods Even-aged Clearcutting Seed tree Shelterwood
14
Regeneration Methods Uneven-aged Single tree selection Group selection
15
Regeneration Methods Two-aged Irregular or reserve shelterwood
Deferment cut
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
18
Site Preparation - Mechanical
Manual felling Manual girdling Shearing Drum chopping Rake-and-pile Mastication Disking Bedding Subsoiling
19
Site Preparation - Chemical
Broadcast Spot or strip Individual stem
20
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
