  • Transcript of "National Forest Planning and NFMA Requirements"

    1. 1. National Forest Planning and NFMA Requirements Karl R. Walters
    2. 2. Purpose of Study <ul><li>Forest Service recently released new planning rules </li></ul><ul><ul><li>What do these changes in the rules mean? </li></ul></ul><ul><ul><li>Will the changes make a difference? </li></ul></ul><ul><ul><li>What are the implications for modelers? </li></ul></ul>
    3. 3. Why is this important? <ul><li>National Forest Planning bogged down </li></ul><ul><ul><li>Time and expense has become exorbitant </li></ul></ul><ul><ul><li>Revisions required every 10-15yrs </li></ul></ul><ul><ul><li>On some forests, taking almost that long </li></ul></ul><ul><li>New rules to reduce time to develop plans </li></ul><ul><ul><li>Less litigation, more implementation </li></ul></ul><ul><ul><li>Focus on sustainable forest management </li></ul></ul><ul><ul><li>Forest health is a major goal </li></ul></ul><ul><li>NFMA (1976) and NPLMA (1976) </li></ul><ul><ul><li>Multiple use-sustained yield concept still applies </li></ul></ul>
    4. 4. Why is this important? <ul><li>What if the Forest Plan isn’t implemented? </li></ul><ul><li>Harvests are significantly lower than allowable across most Regions </li></ul><ul><li>Catastrophic insect & fire damage common </li></ul><ul><ul><li>Fire suppression costs increasing yearly </li></ul></ul><ul><li>Do more with less </li></ul><ul><li>Increased mandates (fire protection on non-Federal land) </li></ul><ul><li>Budgets are being cut, not increased </li></ul>
    5. 5. Highlights of the New Rule <ul><li>Planning framed in EMS (ISO 14001) </li></ul><ul><ul><li>Provides standards for management process, reporting, etc, across NFS </li></ul></ul><ul><li>Streamlined planning </li></ul><ul><ul><li>2-3 yr process </li></ul></ul><ul><ul><li>More internalized evaluation of alternatives </li></ul></ul><ul><ul><li>Public comment on the proposed plan rather than a variety of alternatives </li></ul></ul><ul><li>Allowable sale quantity </li></ul><ul><ul><li>Still subject to LTSY constraints </li></ul></ul><ul><ul><li>Viewed as an upper bound only on timber sales </li></ul></ul>
    6. 6. Implications <ul><li>Auditing for compliance </li></ul><ul><ul><li>EMS requires regular measurement of actions against the plan </li></ul></ul><ul><ul><li>Need to do what you say you’re going to do </li></ul></ul><ul><li>Sustained yield – sustainable management </li></ul><ul><ul><li>Which is it? NFMA requirements at odds </li></ul></ul><ul><li>Planning models </li></ul><ul><ul><li>Smaller, simpler models to determine capacities, interactions, etc </li></ul></ul><ul><ul><li>Spatially explicit to consider smaller scale effects </li></ul></ul><ul><ul><li>One final, detailed model for public comment </li></ul></ul>
    7. 7. Contrived Planning Problem <ul><li>~ 300,000 ac </li></ul><ul><li>Ponderosa pine dominated landscape </li></ul><ul><li>Major concerns </li></ul><ul><ul><li>Forest fires, mountain pine beetle </li></ul></ul><ul><ul><li>Maintaining historical range of variability </li></ul></ul><ul><ul><ul><li>More dispersed age classes </li></ul></ul></ul><ul><ul><ul><li>Greater presence of aspen and hardwoods </li></ul></ul></ul>

    14. 14. The Model <ul><li>Goal programming formulation </li></ul><ul><ul><li>Minimize deviations from goals </li></ul></ul><ul><ul><ul><li>75% of area in wildland urban interface and 1 mile buffer in low or low-moderate fire hazard rating </li></ul></ul></ul><ul><ul><ul><li>Maintain proportions of structural stages within key management areas </li></ul></ul></ul><ul><ul><ul><li>Perform minimum acres of aspen and oak restoration </li></ul></ul></ul><ul><ul><ul><li>Maintain minimum habitat acres in critical management area </li></ul></ul></ul>
    15. 15. Base Run Results <ul><li>Total Sale Program Quantity </li></ul><ul><li>Subject to </li></ul><ul><ul><li>Nondeclining yield (NDY) </li></ul></ul><ul><ul><li>LTSYC-NDY link </li></ul></ul><ul><ul><li>Perpetual timber harvest constraint </li></ul></ul><ul><li>Forest inventory </li></ul><ul><li>Generally increases </li></ul><ul><li>Goal achievement </li></ul><ul><li>Generally under-achieve </li></ul>

    26. 26. Is Sustainable Yield Sustainable? <ul><li>NFMA requires </li></ul><ul><ul><li>Sale quantity < long-term sustained yield </li></ul></ul><ul><ul><li>Departures from NDY ok if consistent with multiple-use </li></ul></ul><ul><ul><li>New rule makes ASQ an upper bound only </li></ul></ul><ul><li>But what if forest health suffers because of NFMA requirements? </li></ul><ul><ul><li>Luckert & Williamson (2005) question SY in the context of Sustainable Forest Management </li></ul></ul>
    27. 27. No NFMA constraints <ul><li>Sale Quantity </li></ul><ul><li>Large variations </li></ul><ul><li>Inventory </li></ul><ul><li>Marginal decrease relative to Base </li></ul><ul><li>Goal achievement </li></ul><ul><li>Better achievement </li></ul><ul><li>Higher forage production </li></ul>

    36. 36. Discussion <ul><li>Use multiple small models to look at issues </li></ul><ul><ul><li>Determine which objectives conflict and which ones complement </li></ul></ul><ul><ul><li>Focus on real trade-offs </li></ul></ul><ul><ul><li>Determine reasonable range of values </li></ul></ul><ul><li>Finally, create a smaller, tightly focused model representing a single alternative </li></ul>
