  1. Fundamentals of Forest Management Planning FOR 272 – Sustainable Forest Management

  2. FOREST MANAGEMENT PRESCRIPTIONS • Prescription = A schedule of activities for a stand, landscape, watershed, or other management unit • Five key elements: • Statement of goals • Understanding of historical processes • Land-type classification • Treatment schedule • Quantitative projection of conditions and outcomes

  3. I. Goals and Objectives • Goals • Timeless statement of intent • Statement of direction, don’t necessarily expect to fully achieve a goal • Objectives • Specific statement of intended accomplishment • Measurable, observable, has a reference to time, an associated cost, and is attainable.

  4. Historical Context for Forest Management in New England

  5. Historical Range of Variability HRV Figure from Aplet and Keeton (1999)

  6. Hurricane Scale: Small Watershed HRV Hurricanes Scale: Drainage Basin HRV Scale: Region HRV Source: Aplet and Keeton (1999)

  7. Changes in Age-Class Distributions 1.0 19th century Current Proportion of Forest Cover Pre-Settlement 0 Young Mature Old-growth Stand Age/Structural Condition

  8. Historical Range of Variability 1 0.9 0.8 0.7 0.6 0.5 Proportion of Landscape in Early-Succession 0.4 0.3 0.2 HRV 0.1 0 1300 1350 1400 1450 1500 1550 1600 1650 1700 Year Figure modified from Aplet and Keeton (1999) using data from Cogbill (2000)

  9. Pre-Settlement: 1600

  10. Early Homestead: 1740

  11. Height of Clearing: 1830

  12. Abandonment: 1850

  13. Old Field White Pine: 1910

  14. Hardwood release and succession: 1915

  15. Young hardwoods: 1930

  16. Stand Improvement Cutting

  17. Commercial Thinning

  18. Shelterwood Harvest

  19. Forest Cover Trends in New England Since European Settlement

  20. Forest Cover in Vermont Data courtesy of Harvard Forest (2003)

  21. Wildlife Population Trends in VT and NH Since European Settlement

  22. Altered Successional Pathways Resulting from a Complex History of Land-use Figure from Foster (1992)

  23. Differences Between Pre-Settlement and Current Forests in VT and NH Forest Composition Species:Abundance: Chestnut Elm Beech Sugar Maple Hemlock White Pine Red Spruce White Birch Cottonwood Pin Cherry Red Maple Communities:Abundance: Old-Growth Forest of All Types Floodplain Silver Maple and Sugar Maple Rich Lowland Oak/Basswood/Ash Forested Wetlands Native Grasslands and Shrublands Functionally Extirpated Sources: Cogbill (2000); McLachlan et al. (2000); Fuller et al. 1998;Foster 1992; Siccama (1971)

  24. Differences Between Pre-Settlement and Current Forests in VT and NH Landscape Pattern • Patch Size • Patch Shape Complexity • Fragmentation vs. Connectivity • Bottomland Openings • Ridgeline and Upper-Slope Openings • Topographic Distribution of White Pine • Topographic Distribution of Red Spruce Sources: Cogbill (2000); Mladenoff and Pastor (1993)
