Silviculture
  • The theory (science) and practice (art) of
    controlling forest establishment, composition,
    structure, and growth

30
Forests Function as Systems
31
Silvicultural Harvests Focus on
Residual Stand Future Stand
32
Cutting
  • Removes Competition
  • Controls Light
  • Redistributes Growth
  • Controls Species Composition
  • Meets Objectives
  • Produces Income (not necessarily money)

33
Thinning
  • Crown
  • Placement
  • Species
  • Condition
  • Quality
  • Density
  • Redistribute
  • Annual Growth

Silvicultural Harvests Focus on
  • Residual Stand What are you leaving?
  • Future Stand What are you providing?

PAs Forest History
  • Period of Exploitation
  • 1880 to 1920
  • 1.6 to 2.0 Billion Board Feet
  • White-tailed Deer nearly extirpated
  • Environmental Conditions
  • 1954 to 2004
  • 1954 513 Million Board Feet
  • 1964 595 Million Board Feet
  • 1978 771 Million Board Feet
  • 1989 1.1 Billion Board Feet
  • 2004 A Good Question

56
The Year 2004 Lets Speculate
  • 1.6 Billion Board Feet annually
  • 17 Million Acres of Timberland
  • Cut per Entry
  • 2,000 Board Feet
  • 3,000 Board Feet
  • 4,000 Board Feet

57
How Much Are We Cutting?
  • Total Annual Cut Acres Cut / Year
  • Volume / Acre Cut
  • 1.6 Billion BF _at_ 2,000 BF/A Acres/Year
  • 1.6 Billion BF _at_ 3,000 BF/A Acres/Year
  • 1.6 Billion BF _at_ 4,000 BF/A Acres/Year

Years to Enter All Stands
  • Total Forest Area Years
  • Acres Cut / Year
  • 17 Million A _at_ 800,000 A / YR Years
  • 17 Million A _at_ 533,333 A / YR Years
  • 17 Million A _at_ 400,000 A / YR Years

Timber Harvesting Assessment Project (THAP)
Findings

If and to what extent is harvesting affecting
timber sustainability?
60

Assessment Variables
  • Species - proportion desired for timber
  • Quality - potential of residuals as sawlogs
  • DBH distribution - stand shifts
  • Regeneration - amt., size, species, deer,
    cutting intensity, interfering plants
  • Tree damage - residual stem and crown
  • Site disturbance - amt., use of erosion and
    sedimentation practices

A Tale of Two Fisheries1
  • Right now, my only incentive is to go out and
    kill as many fish as I can. I have no incentive
    to conserve the fishery, because any fish I leave
    is just going to be picked by the next guy.
  • 1The New York Times Magazine, August 27, 2000
