Fuel – Diesel
Fuel – Natural Gas
About ½ the cost of diesel on energy basis.
Electric utilities, trucking firms, railroads, etc. are switching to gas.
Log trucks fit this concept.
Prices can spike in winter due to heating demands.
Enormous new domestic supplies of this fuel.
Fuel Options Compared

Fuel – Natural Gas
US natural gas supplies are at record levels due to fracking in tight shale formations.
Many shale gas plays are just being developed.
Over-supply & low price of gas is slowing development.
Killing biomass energy opportunities.
Fuel Consumption
Fuel is ~20% of cut and load cost
Diesel range $1.50-$4.75 over past decade
2012 GA/SC logger survey:
21% track fuel use by machine
21% track fuel use by crew
19% do no tracking at all
Benchmarks lacking for comparison
Fuel Consumption Study
Objectives
long-term operational fuel consumption data
per operating hour
per ton produced
mechanized feller-buncher/grapple skidder
pine plantations (clearcut and thinning)
Southeastern coastal plain
Receiving Mill
Buys ~2 million tons annually of pine pulpwood in southeastern Georgia coastal plain
Provided funding for the project
Provided a list of wood suppliers
Suggested 12-15 suppliers as candidates
Received periodic reports showing fuel consumption statistics with no identities of crews or statistics by crew
University of Georgia
Solicited the participation of each supplier
Provided forms, fuel meters, on-site training
Handled all data input and summary
Follow-up calls, email, site visits with suppliers
Periodic reports back to cooperators and funding company
Logging Contractor
Agreed to record & share:
Fuel consumption by machine
Hour meter reading at fill-up
Weekly production for the crew
Installed and maintained fuel meters
Mailed data to us on their schedule – monthly was most common
Received reports from UGA showing their fuel usage compared to others in the study
Fuel meters are theirs to keep

Fuel Usage Conclusions
Fuel consumption to cut/skid/load wood averaged 0.38 gallons per ton.
These crews work flat (but often wet) ground harvesting pine plantations with a limited number of sorts.
These consumption rates likely set a floor rather than an average baseline.
Timber – Recession Impacts
Lumber demand off by 40-50% at one point
Sawtimber prices down 35%
Landowners sitting on thinned sawtimberstands waiting for higher prices…?
Pulpwood demand holding due to pulp and wood pellet markets and shortage of lumber chips
Age class distribution impacts and reduced planting – where will future pulpwood be?
Less final harvest = less replanting

Non-traditional materials Growth
Biomass
Piled residues through grinders –ash content too high for pellets (>5%)
Chipped tops/slash without piling or WTC <2% ash
Residues rely on demand for other primary products
Roundwood (pulpwood) preferred due to control, cost, low ash, etc.

The Future?
It is hard to make predictions, especially about the future – Yogi Berra
We have problems, but very few that stronger markets and higher prices would not solve.
Our logging contractors are becoming even more efficient to survive.
Given access to capital, harvesting capacity can rebound rather quickly.
Trucking can be made more efficient with scales, scheduling, and de-linking from logging.
