  1. Criteria and Indicatorsstate of the processCriterion 2 presented by W. Brad Smith Associate National Program Manager, FIA

  2. Identifying Research Needs

  3. FIA, the keystone of Criterion 2, has reported Main information flow Feedback loop on U.S. forests from local to global Local Sub-State region State Regional/ National Global International multi-process National multi-sector National sector C&I

  4. Make no mistake …. Criterion 2 is about commodities, timber and nontimber However, looking holistically… Indicators 1-4 in Criterion 1 cover area of all forest by type and successional stage and indicators 7 and 9 cover species abundance and change in forests Indicator 26 in Criterion 5 covers biomass in forests by type [and I would suggest some parallelism with Criterion 1]

  5. In the 2003 National Report on Sustainable Forests for Criterion 2: Indicators 2, 4, 10, 11, 12, 13, 31

  6. Islands Am. Samoa Guam Palau Puerto Rico Virgin Is. NMI FSM RMI What are we doing about Criterion 2 gaps? Annualized forest inventory is progressing Implementation in 1999 Implementation in 2005

  7. And, coming soon to a website near you: • Annual estimates of area, growth, removals and mortality for all forest land, current and historic • Annual estimates of volume and biomass on all forest land • Annual updates on forest ownership study results • Annual validation data for spatial tools based on remote sensing [15-20,000 plots per year]

  8. Indicator 14 Nontimber forest products What are they, generally…. • Food • Medicinals • Florals • Oils and resins • Cultural (arts and crafts) • Game and hides

  9. FIA southern NTFP pilot study Identify • Markets • Products • Distribution Then • Test protocols and measures • Estimate value The study is ongoing

  10. Some reported data are still difficult to interpretor lack trends Forest age class data, 2002 Indicator 2

  11. We need to explore surrogates for age-class like average stand diameter? The optimal mix of forests of different average size trees is difficult to define and depends greatly on management objectives. Clearly, the effects of human activity and natural events paint different pictures in different regions. Source: Forest Resources of the United States, 2002 Indicators 2 & 4

  12. If we had known then…. FIA would have cataloged area by forest by type and average diameter class (stand-size class) jointly FIA did it separately for 50 years and it is difficult to recover from pre-digital data. We have data from about 1980 on.

  13. Fusing field and remote sensing data will offer new opportunities for displaying patterns like ownership

  14. Or harvesting

  15. 400 350 300 South 250 200 North Interior West 150 100 Pacific Coast 50 - 1760 1780 1800 1820 1840 1860 1880 1900 1920 1940 1960 1980 2000 Sometimes we pieced seemingly disparate data together to derive meaningful trend information: Regional forest trends in the 48 States, 1760-2000 Basis for chart data: 1940- pres. FIA Field Inventory Reports 1900 – 1930 Forest Service report estimates prior to FIA field inventories. 1850 – 1890 Based on Bureau of the Census land clearing statistics. 1760 – 1840 Based on estimates of forest clearing proportional to population growth. Million acres Indicators 2 & 4

  16. But many questions remain

  17. Like number of hardwood trees in the U.S. by major species, 1963-2002 Even when we have trends, what do they mean? Indicator 9 (Only shows number of trees 5-inches dbh and larger)

  18. Top 10 species in U.S. forests What’s best: Is tree biodiversity best measured by volume or number of trees? Indicator 9

  19. 25 3.5 Growth 20 3.0 Growth 2.5 15 Removals Percent of total live volume 2.0 Billion cubic feet Removals 10 1.5 1.0 5 Mortality 0.5 Mortality 0 0.0 1953 1963 1977 1987 1997 2002 1953 1963 1977 1987 1997 2002 Is an indicator best measured in: Indicator 13 < absolute terms -or - relative terms >

  20. Does ownership matter? As public policy has shifted, removals have moved dramatically from public land in the West to private land in the East in the last 15 years. Indicator 13

  21. ? And, the answer for your favorite indicator is…
