Manual Felling
• Not always practical if large numbers of trees must be removed
• Can damage residual trees
Brushsaw for small stems, brushChainsaw

Tree Girdling
• Double girdle 1 in. deep spaced ~ 6 in. apart
• Later winter, early spring during sap rise
• Diffuse porous species are poor candidates unless herbicide is used

Mechanized Felling
• Mechanized removal– Tracked feller buncher
• Rotating cab with hinged arm
• Steep, uneven terrain
– Hydrostatic feller buncher• Easily maneuverable
• Plantations
– 3-wheeled feller buncher• Lightweight
• Flat terrain

Mechanized Removal
• Brush Hog
– Small trees and brush

Herbicides
• Why herbicide?
– Effective kill of whole plant with no resprout potential
• Uses– Precommerical thinning
– Release treatments
– Improvement cutting
– Site preparation
– Control of invasive species
– Right-of-way maintenance

Herbicide Application Methods
• Cut surface treatments– Frill girdle (Hack and squirt)
– Stem injection
– Cut stump
• Bark, foliage, and soil treatments– Foliar spray
– Basal bark application
– Basal soil spray

Herbicide Types
• Amine formulations (water-based)
– Water used as “carrier”
– Foliar spray, cut surface• Herbicide label will specify mixture for given application and target species
– Common chemicals: • Glyphosate: Roundup, Accord
• Triclopyr: Garlon 3A
• Picloram: Tordon K, Pathway
• Imazapyr: Aresenal
• 2,4-D

Herbicide Types
• Ester formulations (oil-based)
– Basal oil, diesel, or kerosene used as “carrier”
– Cut surface, basal bark• Herbicide label will specify mixture for given application and target species
– Common chemicals: • Triclopyr: Garlon 4
