What was needed? A strategic assessment of western forest biomass!

How much?

Where?

What kind?

Who owns it?

Treatment opportunities?

Potential yields?

Small diameter utilization potential?

Costs ?


The West – A biomass!BIG Place

129.6 million

acres


Forest inventory and analysis data
Forest Inventory and Analysis Data biomass!

Nation’s Forest Census

75 Year History

Comprehensive and Geo-referenced Sampling Frame

Nationally Consistent Sampling Protocols

5 Year Roll Up of National Statistics in RPA

  • Used combination of

  • periodical state and

  • annualized inventories

  • Extrapolation and data

  • synthesis

  • - Special analysis

  • Phase I is remote sensing; 1 plot

  • for 100 ha

  • Phase II is ground sampling; 1

  • plot for 2200 ha

  • Phase III is intensive plots; 1

  • plot for 38,500 ha


Totals (in millions): biomass!

Timberland – 129.6 acres

Biomass – 6855.0 dry tons


Biomass analysis

Acres and Volumes by

  • Condition Class

  • Stand Prescription Treatments (Used Stand Density Index)

  • Utilization (>7-in stem volume; <7-in stem, limbs, and tops)

  • Accessible

    • Terrain

    • Road

    • USED 60% ACCESSIBILITY


Condition Classes biomass!

1 – use prescribe fire

2 – some mechanical treatments

3 – mechanical treatments required

Sdi approach to biomass yields
SDI Approach to Biomass Yields biomass!

  • Stand Density Index approach is:

    • Science-based (species and locality differences are considered)

    • Allows for retention of some small trees as well as the removal of trees in all dbh classes (e.g. sustainability)

    • Provides a conservative and balanced stocking distribution over large areas

    • Doesn't require development of detailed prescriptions for large areas

    • Allows flexibility (Don’t know where trees actually are, so any management system can be accommodated at local scales)

Totals (in millions): biomass!

Treatable timberland – 96.9 acres

Biomass – 6447.4 dry tons

Potential yield – 2154.0 dry tons


Totals (in millions): biomass!

Treatable Cond. 2&3– 66.9 acres

Biomass – 4529.1 dry tons

Potential yield – 1493.4 dry tons


Totals (in millions): biomass!

Treatable Cond. 3– 28.5 acres

Biomass – 1791.1 dry tons

Potential yield – 576.1 dry tons


Small Diameter Utilization Potential biomass!

Volume vs. number of trees!


Small Diameter Utilization Potential biomass!

  • Results

  • 245 million bdt of merchantable products

  • Annual Removal of 8-51 million bdt

  • Twice as much as current mill capacity for

  • Total 101 million bdt of non-merchantable biomass

  • Some MDF, OSB, and pulp capacity

  • Little energy capacity

Potential Yield by Owner

Condition Class 3



A big job ahead
A biomass!big job AHEAD!

  • Total removal volume from Class 2 and 3 is nearly 40 times the annual conventional removal volume

  • The forest types and terrain are highly variable

  • Potential products and markets are also variable

  • Operations have to match the treatment and forest conditions as well as the product options
