  3. Timber Products Company Oregon California Klamath River Yreka California Cascades Scott River N Mt Shasta City Trinity River

  4. Timber Products Company Overview of Presentation • History of “New Forestry” • Timber Products development and implementation of Bioforestry Program. • Timber Products monitoring of Bioforestry Program • Timber Products methods and metrics used for assessment

  5. Timber Products Company New Forestry ? “A kinder, gentler forestry. Is it the answer?” Evergreen Magazine 1989

  6. Timber Products Company New Forestry? “Maintaining stable populations of all species by managing for each species individually is an impossible task. However, biodiversity can be promoted by maintaining the habitat - forest structures - in which the species are found” Dr. Chadwick Oliver Professor, College of Forest Resources University of Washington (Oregon Department of Forestry, An easy guide for structure based forest management, 1998)

  7. Timber Products Company Chapter 7: Variable Retention Harvest Systems Major topics discussed: How to provide structural enrichment of forest stands and landscapes? What to retain? How much to retain? What spatial pattern for retention? Considerations for wind, fire, insects, diseases?

  8. Timber Products Company Timber Products Bioforestry Why?  Maintain ability to manage forestland for the long-term Maintain landscapes of suitable habitat for Northern spotted owl through our Spotted Owl Management Plan. Create complex forest stands and landscapes that will maintain viable populations of early, mid, and mature forest wildlife species.

  10. Timber Products Company Timber Products Bioforestry Establishment of policy in 1995 1. Formalized Existing Efforts 2. Provided Structured Guidelines 3. Documented Policy 4. Set Minimum Standards 5. Provided for Unstructured Application

  11. Timber Products Company Timber Products Bioforestry Overview of Guidelines • Species Diversity • Structural Diversity • Large Woody Debris • Riparian LWD and Snag Retention • Tree Species Seedling Diversity • Adaptive Management

  12. Timber Products Company Timber Products Bioforestry Compliance and Effectiveness Monitoring Completed in 2000 • Forest Resource Inventory Field Data Collection • Global Positioning Systems (GPS) • Entry into Geographic Information Systems (GIS) and relational database.

  19. Timber Products Company Timber Products Bioforestry Why Monitor? • Describe and document policy within stands under active timber management • Describe distribution of Bioforestry stands. • Describe size, quantity, and condition of Bioforestry stands.

  20. Timber Products Company Bioforestry Results: What is the appropriate scale? Tree/Snag/Log Habitat Retention Area Harvest Unit Section Small Timber Harvest Plan Planning Watershed Watershed Ecosystem Large

  21. Timber Products Company Bioforestry Results: Section 25 T46N R04W Stand = 23.69 ac. Retention = 0.73 ac. % Retention = 3.1% Willow Creek Mountain THP (2-97-180-SIS(6) California Cascades, Northern California

  22. Timber Products Company GIS Bioforestry stand located at Section 25 T46N R04W Stand = 23.69 ac. Retention = 0.73 ac. % Retention = 3.1% N Willow Creek Mountain THP (2-97-180-SIS(6) California Cascades, Northern California

  23. Timber Products Company Bioforestry in Section 34 T47N R4W Stand = 24.6 ac. Retention = 1.2 ac. % Retention = 4.9% West Dorris THP (2-96-005-SIS(6) California Cascades, Northern California

  24. Timber Products Company Bioforestry in Section 26 T47N R4W Stand = 24.6 ac. Retention = 1.2 ac. % Retention = 4.9% N West Dorris THP (2-96-005-SIS(6) California Cascades, Northern California

  25. Timber Products Company Bioforestry Retention in Section 4 T46N R4W Stand = 17.7 ac. Retention = 0.77 % Retention = 4.4% West Dorris THP (2-96-005-SIS(6) California Cascades, Northern California

  27. Timber Products Company Bioforestry Stand in Section 27 T48N R09W Stand = 26.2 ac. Retention = 0.6 ac. % Retention = 2.3% Wards Gap THP (2-98-344-SIS(6) Beaver Creek Watershed Klamath River, Northern California

  28. Timber Products Company Bioforestry Stand in Section 27 T48N R09W Stand = 26.2 ac. Retention = 0.6 ac. % Retention = 2.3% % Retention = 5.0% % Retention = 2.9% Wards Gap THP (2-98-344-SIS(6) Beaver Creek Watershed Klamath River, Northern California

  29. Timber Products Company Bioforestry Results: What is the appropriate scale? Tree/Snag/Log Habitat Retention Area Harvest Unit Section Small Timber Harvest Plan Planning Watershed Watershed Ecosystem Large

  30. Timber Products Company Bioforestry Results: Planning Watershed scale Balance of various wildlife guilds habitat use Data can be collected and analyzed for planning watershed Some regulatory and legal support for planning watershed Compliance monitoring can be reviewed at THP level

  31. Timber Products Company Bioforestry Results:Individual Retention Areas • < 1/20th = 26(16%) • 1/20th = 134(84%) n = 160

  32. Timber Products Company Bioforestry Results:Individual Stands <2% Retention = 48% >2% Retention = 52% n = 48 Number of Stands

  33. Timber Products Company Bioforestry Results:Planning Watersheds <2% Retention = 40% >2% Retention = 60% n = 15 Number of Watersheds

  34. Timber Products Company Bioforestry Results:Ecosystems

  35. Timber Products Company Bioforestry Results: Species distribution

  36. Timber Products Company Bioforestry Results: Diameter distribution Trees per acre over11’’dbh

  37. Timber Products Company Bioforestry Results: LWD Loading by Stand n = 48 Trees per acre over11’’dbh Number of Stands

  38. Timber Products Company Bioforestry Results: Snag distribution by Stand Number of Stands

  39. Timber Products Company Bioforestry Results: Representation of pre-harvest distributions An Example: Basal Relative (Willow Creek Mtn) TPAAreaQMD8Density Pre-harvest Condition 187 89 13.3 24 Retention Area Condition 270 190 12.9 54 Another Example: (Wards Gap) Pre-harvest Condition 381 152 17.1 37 Retention Area Condition 277 215 16.2 54

  40. Timber Products Company Significant sampling and data analysis questions? Are there field sampling methodologies that would be both statistically valid and quicker? What are the appropriate data metrics (ie. Qmd, BA) for assessing these forest stands? At what scale do biometricians feel assessment should take place? Which statistical methods would be most appropriate for measurement and comparison of Bioforestry stands?

  41. Timber Products Company Bioforestry: Future Plans and Monitoring Compliance Monitoring Adaptive Management feedback in 2001. Policy development on Planting, Spraying, PCT, Burning, Site Preparation, Access of firewood cutting. Effectiveness Monitoring Wildlife use focusing on neotropical migrants, small mammals and amphibians Trend Monitoring Forest growth and decay of retention areas including effects of shade, water uptake,disease, etc.
