Timber Damage Assessment
2
Initial Map of Potential Damage (SRS)
3
Texas Forest Service Aerial Survey
  • Aerial recon began Monday, September 26 with
    mapping of outer damage boundary
  • Refined map with 4 damage zones produced on
    Tuesday night, September 27

Timber Damage Field Operations
  • 10 Texas Forest Service Forest Inventory
    Analysis crews worked in the field September 28
    29
  • 222 plots taken over 2 days
  • Fuel, lodging, and transportation issues
  • Crews collected
  • Percent damaged pine and hardwood
  • Percent affected pine and hardwood
  • GPS coordinate
  • Forest stand type
  • Forest stand age
  • Forest stand density

Results of Timber Damage Assessment
  • Field data was applied to current FIA data on
    September 30 to estimate
  • Total value damaged only timber
  • 462 million
  • Total value damaged affected timber 833
    million
  • Damaged mortality, salvage needed
  • Affected mortailty not imminent, salvage may or
    may not be needed

9
Results of Timber Damage Assessment
  • Field data was applied to current FIA data on
    September 30 to estimate
  • Total volume damaged timber
  • 533 million cubic feet
  • Total volume damaged affected timber 967
    million cubic feet

10
Results of Timber Damage Assessment
  • Field data was applied to current FIA data on
  • September 30 to estimate
  • Total poletimber damage 1.5 million cords (1.2
    million cords affected)
  • Total sawtimber damage 2.1 billion board feet
    (1.7 billion board feet affected)

11
Timber Damage Results by County
12
Timber Damage Results by Ownership
13
Putting Damage in Perspective
  • Volume of damaged timber (533 million cubic feet)
    is slightly less than the total volume of growing
    stock removals (harvests) in 2004 (645 million
    cubic feet)
  • Volume of damaged affected timber (967 million
    cubic feet) is about 6 percent of the overall
    timber volume in East Texas (15.7 billion cubic
    feet)

14
Potential Implications of Timber Damage
  • Even greater need for increased reforestation
  • Possible water quality issues from damage to
    Streamside Management Zones
  • Greater understanding of more resistant forest
    stand ages and densities
  • Long-term timber supply for economic development
