significant landform and soil characteristics
Significant Landform and Soil Characteristics
  • Shoulder and Back Slopes
    • Hazelton Dekalb Association (25-80% slopes, very rocky, well drained)
    • Limitations: too steep, boulders, low pH, and largely inaccessible
  • Foot Slopes
    • Laidig and Buchanan Soil Series (8-25% slopes, rocky, well drained)
    • Limitations: steep, rocky, and low pH
  • Toes Slopes
    • Laidig and Buchanan Soil Series (5-15% slopes, rocky, moderately well drained)
    • Limitations: rocky and low pH
  • Valley Floor
    • Andover and Buchanan Soil Series (0-8%, 8-15% slopes, fragipan)
    • Limitations: Sensitive trout stream and poorly drained soils

timber management plan1
Timber Management Plan
  • Units 1, 3, 5
    • Not managed for timber, but for recreation
      • Hiking trails, foot bridges, overlooks, parking areas
      • Haul road and bridge will be constructed in unit 3, in order to access units 4 and 5
    • Very large riparian buffer to protect trout stream and water resource
timber management plan2
Timber Management Plan
  • Timber Management Units 2 and 4
    • Managed for oak (unit 2 and 4) and tulip poplar (unit 4)
    • Two-stage shelterwood prescription
      • w/ long-term residuals
    • Chainsaw felling and grapple skidding
    • Slash scattered and left on site
    • Liming to adjust pH from 4.6 to 6.0
infrastructure construction and water control
Infrastructure Construction and Water Control
  • Haul roads
    • Broad-based dips, water bars, French mattress, culverts, “day-lighting”
    • Creek crossing (permanent bridge) for tri-axle trucks
  • Skid trails
    • Non-bladed, concentrated operations, water bars
    • Reusable
  • Log landings
    • Offset from Licking Creek Rd
    • Reusable
site retirement
Site Retirement
  • Haul roads to offset landings
    • Straw + wildlife grass seed mix
    • Vehicle access restricted
  • Log landings
    • Ruts filled
    • Slightly graded
    • Straw + wildlife grass seed mix
  • Skid trails
    • Ruts filled
    • Permanent water bars
    • Grass seed mix + native vegetation
soil impacts units 1 3 5
Soil Impacts Units 1, 3, 5

Impact

Control

Isolate compaction to trails, overlooks, and haul roads

Vegetation on the sides of the trail will help control erosion

Confined to trails and roads

Confined to trails and roads

Intact forest canopy will redeposit organic matter back to the trails

  • Compaction
  • Runoff/Erosion
  • Loss of fertility due to movement of nutrients to inaccessible micropores
  • Less aerated conditions leads to loss of microbial activity
  • Mixing/loss of organic matter
soil impacts units 2 and 4
Soil Impacts Units 2 and 4

Impact

Control

Use of the same roads, skid trails, and logging decks for both harvests

Preservation of long term residual trees will help hold the soil in certain areas

Leaving of slash on site will help redeposit lost organic matter

  • Compaction
  • Runoff/Erosion
  • Loss of organic matter inputs
  • Loss of fertility due to movement of nutrients to inaccessible micropores
  • Less aerated conditions lead to loss of microbial activity
impacts on water quality on and off site
Impacts on Water Quality On and Off-Site
  • Units 1, 3, 5 will have no significant affect on the water quality on or off site
  • However harvesting units 2 and 4 could have an impact both on and off-site
    • By leaving unit 3 unharvested and positioned downhill of the harvesting units we leave a very large riparian buffer to protect the trout stream and reduce if not eliminate the water quality impacts on/off-site.
    • Additionally the construction of high quality foot bridges and haul road bridges ensure that any stream crossing has minimal impact.
long term timber sustainability
Long-Term Timber Sustainability
  • Completely preserves the timber in units 1, 3, 5
  • Two stage harvest with a heavy emphasis on desirable species regeneration
    • Preservation of long term residual seed trees
    • Site preparation can be completed if necessary for regeneration to establish
  • Establishing regeneration is one of the most important goals of our harvest in order to obtain long term ecological and economical sustainability of the stand.
long term soil and water quality
Long-Term Soil and Water Quality
  • The greatest threat to long term soil sustainability is compaction
    • We combat this by concentrating our compaction to the same haul roads and skid trails as much as possible
    • Use the same roads and trails for future harvest
    • The use of residuals will help to slow the kinetic energy of rainfall and hold soil in place
    • Leaving slash will help increase the organic matter on the site
  • Water quality on the tract and downstream will be controlled by a large riparian buffer that will prevent any long term water quality issues
conclusion
Conclusion
  • Overall our timber harvesting plan focuses on sustainability on a variety of different levels which should allow for long term timber production on the stand.
