Forest cutting and reproducing techniques 29.03 Environmental and Natural Resources I
Intermediate Cuttings • Cuttings made between reproduction and harvest in a forest • Thinning • Liberation • Sanitation • Salvage • Removal of undesirable trees • Prescription Burning
Intermediate Cuttings • The different types of cuttings are dependent upon: • Climate • Tree species • Owner and manager objectives
Thinning • When only some of the trees in the stand are removed • Reduces the competition for essential needs from other trees
Liberation • Removal of the taller, dominant trees from a stand
Sanitation • Cutting that removes the injured, diseased, or insect-infested trees from the stand
Salvage • Cutting that involves removal of trees that are dead or damaged by storms, construction, etc.
Removal • Removal of undesirable trees involves removing trees that could be compared to weeds • Forked trees • Crooked trunks • Pine trees in a hardwood stand
Prescription Burning • Controlled burning of the undergrowth in a forest
Harvest Cuttings • Selective Cutting • Shelterwood Cutting • Seed-tree Cutting • Coppice Cutting • Clear Cutting
Selective Cutting • Individual trees are selected for harvest based on maturity, size, species, etc. • Goals are to produce an income and a better timber yield
Shelterwood Cutting • Harvesting a mature forest in two or three stages
Seed-tree Cutting • The entire stand is removed except for a few of the best trees that are left to produce seeds
Coppice Cutting • Similar to seed-tree cutting • Rather than remaining trees providing seed, the remaining trees develop root suckers to produce new trees
Clear Cutting • All the trees in a stand are harvested at one time • Most economical and most controversial
Reproducing the Forest • Natural Seeding • Direct Seeding • Cuttings • Plant Seedlings
Natural Seeding • Allowing trees to naturally reseed to produce new growth • Economical • Least amount of control by the forest manager
Direct Seeding • Applying tree seeds directly to the desired area • Can be done by: • Hand • Seed spreaders • Grain drills • Aircraft
Cuttings • Cuttings can be taken from existing trees, allowed to root, and then planted
Plant Seedlings • Planting a nursery-produced seedling • More labor and expensive • Allows complete control over reproduction • Tends to get results quickly
Plant Seedling Continued • Some states offer government rebates to landowners who reforest their land after harvest • The most certain and quickest way to reproduce trees
