1. No action is not an option; we must continue to move forward
2. Convene a recovery team to develop a spotted owl recovery plan
3. Establish interagency team with the role of setting a provincial context for where fuel reductions would facilitate maintenance and restoration of spotted owl habitat.
2005 Workshop - Recommendations
1. Take it on the road
2. Produce landscape prioritization maps. Senior Managers Group supported moving forward and established an interagency team to develop and distribute the maps
3. Action is needed. Federal agencies should work together, utilizing map product developed in #2 for project area ID.

A fire behavior mapping and analysis program that computes potential fire behavior characteristics (spread rate, flame length, fireline intensity, etc.) over a landscape under constant weather and fuel moisture conditions. Outputs are to be used for making fire and land management decisions.

Active - sustained runs through the canopy will be observed that may be independent of surface fire activity.
3
Passive - isolated torching of single or groups of trees will be observed and canopy runs limited to short distances.
2
Surface - little or no tree torching will be expected1
