  1. A Conceptual Approach to Prioritizing Landscapes for Fuels Treatments in Northern Spotted Owl Habitats

  2. AcknowledgementsScott CenterCindy DoneganLynn Gemlo

  3. Problem Statement The paradox facing land managers today is the need to treat northern spotted owl habitat in order to save it (Agee 1992).To achieve this, we need to identify priority areas for reducing the risk of stand replacement wildfires in areas with high habitat values.

  4. Conceptual Model Resource Values Risk Factors One to many One to many Composite Risk Map Composite Values Map Landscape Prioritization Map

  5. Northern Spotted Owl and the Northwest Forest Plan • 18.1 million acres of habitat • capable Federal land • 9.3 million acres of habitat • Declining populations • Habitat at risk

  6. Lightning Ignited Wildfire during the First Decade (1994-2003) 50% were caused by lightning 75% of the total area burned was the result of lightning Around 13,200 wildfires were recorded on Federal lands, burning about 1.7 million acres

  7. Wildfire Density Map ( # Fires / 100 mi²) Moderate Density Low Density High Density

  8. Largest Wildfires ( first decade ) >15,000 acres in WA B&B Complex >10,000 acres in OR Tiller Complex Biscuit Fire >5,000 acres in CA

  9. Resulting in Loss of Habitat ( first decade ) 1% Habitat Loss ( East Cascades ) 1% Habitat Loss ( West Cascades) 7% Habitat Loss ( Klamath ) 230,000 acres of habitat were lost range wide to wildfire in the 1st decade. About a 1.3% decrease across the range. About 5x as much than was lost from clearcut timber harvesting.

  10. Declining Stationary Spotted Owl Population Trends ( Anthony et al. 2005 ) NSO Demography Areas

  11. Conceptual Landscape Analysis Area • Southwestern Oregon • Stationary populations • Active wildfire history

  12. Analysis Area Location Map Southern Oregon Coastal Basin ( HUC 3 ) 8.2 million total acres 41% Federal land Coos Bay Roseburg Grants Pass Medford Ashland

  13. Analysis Area Location Map USFS = 2,039,431 ac BLM = 1,292,492 ac NPS = 36,639 ac Coos Bay Roseburg Grants Pass Medford Ashland
