29Silviculture
- The theory (science) and practice (art) of
controlling forest establishment, composition,
structure, and growth
30Forests Function as Systems
31Silvicultural Harvests Focus on
Residual Stand Future Stand
32Cutting
- Removes Competition
- Controls Light
- Redistributes Growth
- Controls Species Composition
- Meets Objectives
- Produces Income (not necessarily money)
33Thinning
- Crown
- Placement
- Species
- Condition
- Quality
- Density
- Redistribute
- Annual Growth

54Silvicultural Harvests Focus on
- Residual Stand What are you leaving?
- Future Stand What are you providing?
55PAs 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
56The 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
57How 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

58Years 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

59 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

69A 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
