  2. MOFEP • Background • Past • Present • Future

  3. The 5 Cs • Cooperation • Collaboration • Compromise • Commitment • Communication

  4. MOFEP BEGINNING CRISIS DESIRE

  5. EARLY HISTORY MISSOURI STATE HISTORICAL SOCIETY

  6. EARLY HISTORY MISSOURI STATE HISTORICAL SOCIETY

  7. EARLY HISTORY

  8. EARLY HISTORY

  9. MDC GUIDING PRINCIPLES • Biological information guiding management decisions • Goal to have healthy: • Forests • Fish and Wildlife Populations

  10. EARLY FORESTRY GOAL

  11. FOREST-BIRD PROJECT John Faaborg - UMC Rick Clawson - MDC

  12. FOREST-BIRD PROJECT Descriptive Study Cause and Effect Relationships

  13. 3 AVENUES OF SCIENCE • Descriptive Studies • Can be first step • Describe • Forest Inventory

  14. 3 AVENUES OF SCIENCE • Descriptive Studies • Confirmatory Studies • Multiple Hypotheses • Model • Model fitting or selection based on data

  15. 3 AVENUES OF SCIENCE • Descriptive Studies • Confirmatory Studies • Observational Studies

  16. 3 AVENUES OF SCIENCE • Descriptive Studies • Confirmatory Studies • Experiments • Randomization • Replication • Control • Shows cause and effect

  17. TYPICAL FOREST-WILDLIFE STUDY • Observational Study • Conducted on units already treated • Many factors influence results • Many different explanations for results obtained • Often do not account for surrounding conditions • Results need to be tested • Results should probably not be used to make critical management decisions

  18. BUT MANAGEMENT MUST BE DONE IN THE FACE OF UNCERTAINTY

  19. Scientists and Managers working together? Magic of MOFEP

  20. USE OF EXPERIMENTS

  21. USE OF EXPERIMENTS

  22. MOFEP

  23. FOREST MANAGEMENT PRACTICES FOR MOFEP

  24. MOFEP SITE SELECTION • Missouri Dept of Conservation lands • >600 acres • Contiguous tracts – minimal edge • 40+ years since last manipulation • Southeast Missouri Ozarks • Close proximity to each other • 10 found, 9 would work

  25. MOFEP EXPERIMENTAL DESIGN • Randomized Complete Block Design • 3 blocks with 3 MOFEP sites each • Subjective information used to create blocks

  26. MOFEP EXPERIMENTAL DESIGN Km 0 1 2

  27. MOFEP EXPERIMENTAL DESIGN • Randomized Complete Block Design • 3 blocks with 3 MOFEP sites each • Subjective information used to create blocks • Each treatment randomly assign to a single site within a block

  28. MOFEP EXPERIMENTAL DESIGN Km 0 1 2

  29. MOFEP CONCEPTUAL ECOSYSTEM MODEL

  30. STUDIES NUTRIENTS Carbon and sulfur transformation Carbon flux and storage Nutrient cycling SOILS Soils of MOFEP sites Nutrient cycling GEOLOGY and TOPOGRAPHY Soils of MOFEP sites CLIMATE Microclimate

  31. STUDIES OVERSTORY and UNDERSTORY Overstory Stump sprouting Tree cavity Down wood coarse debris Genetics Plant distribution and diversity Canopy mapping Acorn production Oak chemistry GROUND FLORA Ground flora Lichens Lichens SOIL ALLIES Armillaria

  32. STUDIES HERVIVORES Birds Small mammals Herptofauna Oak herbivores Caterpillars INSECTIVORES Birds Small mammals Herptofauna CARNIVORES Birds Small mammals Herptofauna PARASITES/PATHOGENS Ticks DECOMPOSERS Leaf litter arthropods

  33. STUDIES SITE HISTORY Fire history MANAGEMENT Harvest impacts Timber harvest and value Treatments POLICY Information from all other studies impact policy DEMAND Economics of management treatments

  34. PROGRESS • Pre-treatment and post initial entry data collection • Initial entry harvest completed

  35. PROGRESS

  36. EVEN-AGED MANAGEMENT • 10% of site in “old growth” • 10% seedling • 20% small trees (2.5 – 5.5 inches) • 30% poles (5.6 – 11.5 inches) • 40% sawtimber (>11.5 inches) • 100 – 105-year rotation • 10 – 15-year re-entry (20-year re-entry?)

  37. UNEVEN-AGED MANAGEMENT • 10% of site in “old growth” • Largest diameter tree = even-aged management • Residual basal area – B-level stocking • Q-value – 1.3 – 1.7 • Single tree and group selection • Trying for equivalent of 100 – 105-year rotation

  38. NO-HARVEST MANAGEMENT • No anthropogenic manipulation of trees

  39. MOFEP GOAL To Determine the Effects of Forest Management on Plants and Animals of the Ozark Forests (i.e., follow the trajectory of MDC forest management practices)

  40. Science into practice… • MOFEP as adaptive management • Evaluating management systems rather than specific management actions MOFEP Management • Regeneration in EAM; Guiding curves in UAM • Inference to other state forests under state-of-the-art practice of EAM, UAM, and NHM.

  41. 3 General Technical Reports Published Achievements… • New information • Technology transfer: >200 papers produced • Web Site: http://mofep.mdc.mo.gov • Collaboration among agencies and institutions as well as managers and scientists
