Pete Holmberg - Early Seral Foresty: A State Trust Lands Perspective

  1. 1. Early Seral Forestry: A State Trust Lands Perspective “Keeping Common Species Common”
  2. 2. Agenda <ul><li>Policies </li></ul><ul><li>Planning as Related to Early Seral Stages </li></ul><ul><li>Silviculture & Other Disciplines </li></ul><ul><li>Examples </li></ul><ul><li>Techniques and Field Craft </li></ul><ul><li>Summary—The Process </li></ul>
  3. 3. Policies <ul><li>Tenets of The Trust Mandate </li></ul><ul><ul><li>Prudent person doctrine </li></ul></ul><ul><ul><li>Undivided loyalty to the trusts </li></ul></ul><ul><ul><li>Intergenerational equity of benefits </li></ul></ul><ul><ul><li>Maintaining future options </li></ul></ul><ul><li>WA-DNR’s Policy for Sustainable Forests </li></ul><ul><ul><li>Forest land planning determines rotation age </li></ul></ul><ul><ul><li>Landscapes are issue driven </li></ul></ul><ul><li>WA-DNR’s HCP </li></ul><ul><ul><li>Multi-species — entire Endangered Species Act spectrum </li></ul></ul><ul><ul><li>Adaptive management based </li></ul></ul><ul><li>Cohort Management </li></ul><ul><ul><li>Enables managing single stands for multiple objectives </li></ul></ul><ul><ul><li>Identifies and manages objective-specific stand cohorts </li></ul></ul><ul><ul><li>Accounts for silvics of tree species </li></ul></ul>
  4. 4. Planning as Related to Early Seral Stages <ul><li>Northern Spotted Owl—NSO Landscapes </li></ul><ul><ul><li>Longer rotations—At least 50 percent of each landscape in structural stages </li></ul></ul><ul><ul><li>SO : Up to 50 percent of each landscape could be in early seral stands </li></ul></ul><ul><li>General Ecological Management (GEM) Landscapes </li></ul><ul><ul><li>Shorter rotations </li></ul></ul><ul><ul><li>Most of landscapes in competitive exclusion or earlier seral stages </li></ul></ul><ul><li>KEY : Formulating and Integrating Objectives for: </li></ul><ul><ul><li>Landscape </li></ul></ul><ul><ul><li>Unit-Rotation </li></ul></ul><ul><ul><li>Unit-Activity </li></ul></ul>
  5. 5. Techniques and Field Craft <ul><li>At the Unit Scale: Cohort Management </li></ul><ul><ul><li>Unit Rotational Objectives Represented by Distinct Stand Cohort(s) </li></ul></ul><ul><ul><li>Rotational Silvicultural Prescriptions (Chronology of Events—Over a Rotation—That Best Achieve Unit/Stand Objectives) Include Activities of: </li></ul></ul><ul><ul><ul><li>Planting (early seral): mix shade tolerant and intolerant species </li></ul></ul></ul><ul><ul><ul><li>Variable Density Thinning (VDT): retains a portion of early seral </li></ul></ul></ul><ul><ul><ul><li>Variable Retention Final Harvest: around 15 percent left in late seral cohort aggregates; remainder is early seral </li></ul></ul></ul><ul><li>At the Landscape Scale: </li></ul><ul><ul><li>Ample opportunities – accidental or not – for early seral habitat </li></ul></ul><ul><ul><li>Sustain between 30 and 60 percent of landscapes in early seral conditions, depending upon landscape objectives </li></ul></ul>
  6. 7. Summary—the Process <ul><li>Objectives for early seral management are defined and quantified by disciplines from whom concerns emanate </li></ul><ul><ul><li>Unit-rotational scale </li></ul></ul><ul><ul><li>Landscape scale </li></ul></ul><ul><li>Foresters devise unit-level rotational silvicultural prescriptions that best achieve unit-rotational objectives </li></ul><ul><li>Foresters define objective-specific stand cohorts and plan their presence on appropriate spatial and temporal scales </li></ul><ul><li>Activity objectives are drawn from rotational prescriptions with a focus on refinement of imminent activities </li></ul><ul><li>Landscapes are perpetuated in desired proportions of early and later seral stand conditions </li></ul>
  7. 8. <ul><li>Questions? </li></ul>
  8. 9. Q&A Slides on --What is Silviculture? --Early Seral TTs in Older Forest Objectives
  9. 10. Silviculture & Other Disciplines <ul><li>“ . . . the art and science of cultivating forests to achieve objectives” </li></ul><ul><li>Thus, silviculture is the tool; it does not have its own objectives </li></ul><ul><li>Objectives at stand and landscape levels must be expressed by their associated disciplines (i.e., wildlife biologists, financial interests, etc.) </li></ul><ul><li>Objectives must be defined in terms of arrays of threshold targets i.e., discrete and measurable stand parameters </li></ul>
  10. 11. Older Forest Objectives: Some Retention of Early Seral Conditions <ul><li>Landscape : Sustain at least 50% of SOMU in sub-mature NSO habitat ( i.e., 50% of SOMU could be early seral stands ) </li></ul><ul><li>Unit-Rotational : Attain sub-mature NSO habitat </li></ul><ul><ul><li>Main canopy at least 30 percent conifer </li></ul></ul><ul><ul><li>Curtis’ RD > 50 for trees > 4 inches DBH </li></ul></ul><ul><ul><li>115 to 270 trees per acre for trees > 4 inches DBH </li></ul></ul><ul><ul><li>Dominant and co-dominant trees > 85 feet in height </li></ul></ul><ul><ul><li>At least 3 snags or cavity trees per acre > 20 inches DBH </li></ul></ul><ul><ul><li>At least 5 percent of the ground covered with LDWD </li></ul></ul><ul><li>Activity : VDT to average Curtis’ RD 45 for trees > 12 inches DBH </li></ul><ul><ul><li>Vary RD by +/- 8 RD points over 85% of area on a scale of ½ to 5 acres </li></ul></ul><ul><ul><li>Create skips and gaps over 15% of area on a scale of ½ to 5 acres </li></ul></ul><ul><ul><li>Leave/create > 3 snags/ac > 20 inches DBH </li></ul></ul><ul><ul><li>Leave/create at least 5 percent ground cover of LDWD </li></ul></ul><ul><ul><li>Leave all bigleaf maple with 3 stems or less </li></ul></ul>
