  1. Analysis of Annual Forest Inventory Data in ME and PA William H. McWilliams, Carol A. Alerich, Tonya W. Lister, and Randall S. Morin USDA Forest Service, Northeastern Research Station, Forest Inventory and Analysis Show You What We Have Found Out About Penn’s Woods Examples of New Analyses For the 5-Year Report

  2. Regeneration Study: 2001 Exotics Survey: New in 2003 Associated Vegetation Tree Seedlings Progress Update - Inventory

  3. Annual Reporting, 2001 and 2002 Annual Reporting, 2003/4 Progress Update - Reporting • Five-Year Reporting: • Penn State Issues Conference, April 26-27, 2005 • Comprehensive Report

  4. Mega-Trends: Land-Use Change Forest Land Base is Stable

  5. Mega-Trends: Land-Use Change Urbanization Population Density Nonforest 0 1-25 25-50 Parcelization Fragmentation 50-100 Forest 100-250 250-500 500-1000 >1000 Urban area

  6. Forestland Dynamics

  7. Parcelization

  8. Fragmentation

  9. Fragmentation

  10. Mega-Trends: Structure Distribution of Forest Land by Stand-size Class 59% 49% 49% 28% 23% 11%

  11. Mega-Trends: Structure Number of Growing-Stock Trees Per Acre

  12. Mega-Trends: Composition Oak is Decreasing and Red Maple is Increasing

  13. Mega-Trends: Composition

  14. Mega-Trends: Composition

  15. Mega-Trends: Composition

  16. Current Threats Ailanthus vs. Oak + 19% + 57% + 77% + 15% Inventory is Increasing at a Slower Rate than in the Past Alien Pests are Here and More are on the Way Advance Regeneration is Lacking and Options Are Expensive Invasive Plants are Here and Expanding Their Influence Effects of Urbanization, Parcelization, and Fragmentation Reduce Management Options Composition and Structure are Changing

  17. Management and Policy Implications Financially Mature, High-Value Stands Predominate PA’s forested landscape “Timber Availability” is less than FIA Data Imply Timber Industry Will Need to Adapt to Species Like Red Maple Recreation Value is Approximately Equal to Timber Value in Many Areas Methods to Project Current Conditions into the Future Need to be Developed Better Wildlife Habitat Models Would Help Gauge Prospective Trends Stand Rehabilitation will be Needed in Disturbed stands with Poor Regeneration Sustainable Forestry on Private Lands Needs Assessed Prepare Management Strategies for Late Successional and Old Growth Stands Strategies for Invasive Plants and Pests Need Further Development

  18. Castanea dentataMap Regional Study Examples

  19. What, Where, and When of the Next Spruce/Fir Forest? Frequency of Spruce Budworm Defoliation

  20. Next 20 Years of Ingrowth 4-inch Class 3-inch Class 5 Years 10 Years Low 2-inch Class 1 inch Class High 15 Years 20 Years Principal Findings: The Next Generation of Spruce/Fir Forest (Where and When?) Current Distribution of Saplings

  21. Red Spruce Balsam Fir Eastern White Pine % BA/AC Paper Birch Beech Northern Red Oak Principal Findings: Inventory (Where?) Where are the Major Species Concentrated?

  22. Forest Health: Balsam Fir

  23. Forest Health: American Beech

  24. Forest Habitat Types

  25. Forest Diversity

  26. Late-Succession Forests

  27. ?

  28. The End

  29. What We Can’t Tell You Now Less Than 50% of Plots Were Remeasured Old Design New Design Only Central Portion Remeasured! Only About 10% of Trees Remeasured the First Time Through Growth, Removals, and Mortality Are Not Statistically Sound, Yet We Will Remeasure More Trees This Season Than We Did in the First Five Years!

  30. Carbon Stocks and Accumulation Tree Carbon Per Hectare by U.S. County 1015 grams by eco-component National Reporting Examples

  31. Distribution of Mixed-Oak Stands in the Eastern US Mixed-Oak Stands by Stand-Size Class Quercus spp. Map

  32. Population Density Nonforest 0 1-25 25-50 50-100 Forest 100-250 250-500 500-1000 >1000 Urban area Urbanization

  33. Parcelization – Private Forestland (Source National Woodland Owner Survey, 1994)

  34. Fragmentation

  35. Habitat Concerns?

  36. Forest Interior Migrants Generalists Specific Threatened Habitat Concerns?

  37. Late-Successional and Old Growth Forests Mixed Oak 0 100 200 300 Age / Size (After Whitman and Hagen, 2004) Quantify Extent and Character Spatial Distribution For Major Forest Community Types (follow Fike and Jenkins)
