4. 01/30/2007Pete.Holmberg@wadnr.gov4 Planning as Related to Early Seral Stages Northern Spotted OwlNSO Landscapes –Longer rotationsAt least 50 percent of each landscape in structural stages –SO: Up to 50 percent of each landscape could be in early seral stands General Ecological Management (GEM) Landscapes –Shorter rotations –Most of landscapes in competitive exclusion or earlier seral stages KEY: Formulating and Integrating Objectives for: –Landscape –Unit-Rotation –Unit-Activity

5. 01/30/2007Pete.Holmberg@wadnr.gov5 Techniques and Field Craft At the Unit Scale: Cohort Management –Unit Rotational Objectives Represented by Distinct Stand Cohort(s) –Rotational Silvicultural Prescriptions (Chronology of EventsOver a RotationThat Best Achieve Unit/Stand Objectives) Include Activities of: Planting (early seral): mix shade tolerant and intolerant species Variable Density Thinning (VDT): retains a portion of early seral Variable Retention Final Harvest: around 15 percent left in late seral cohort aggregates; remainder is early seral At the Landscape Scale: –Ample opportunities – accidental or not – for early seral habitat –Sustain between 30 and 60 percent of landscapes in early seral conditions, depending upon landscape objectives

10. 01/30/2007Pete.Holmberg@wadnr.gov10 Silviculture & Other Disciplines... the art and science of cultivating forests to achieve objectives Thus, silviculture is the tool; it does not have its own objectives Objectives at stand and landscape levels must be expressed by their associated disciplines (i.e., wildlife biologists, financial interests, etc.) Objectives must be defined in terms of arrays of threshold targets i.e., discrete and measurable stand parameters

11. 01/30/2007Pete.Holmberg@wadnr.gov11 Older Forest Objectives: Some Retention of Early Seral Conditions Landscape: Sustain at least 50% of SOMU in sub-mature NSO habitat (i.e., 50% of SOMU could be early seral stands) Unit-Rotational: Attain sub-mature NSO habitat –Main canopy at least 30 percent conifer –Curtis RD > 50 for trees > 4 inches DBH –115 to 270 trees per acre for trees > 4 inches DBH –Dominant and co-dominant trees > 85 feet in height –At least 3 snags or cavity trees per acre > 20 inches DBH –At least 5 percent of the ground covered with LDWD Activity: VDT to average Curtis RD 45 for trees > 12 inches DBH –Vary RD by +/- 8 RD points over 85% of area on a scale of ½ to 5 acres –Create skips and gaps over 15% of area on a scale of ½ to 5 acres –Leave/create > 3 snags/ac > 20 inches DBH –Leave/create at least 5 percent ground cover of LDWD –Leave all bigleaf maple with 3 stems or less
