Our QuestionsOur Questions
• Is it feasible to conduct long-term studies of the Mt Washington population?
• Is there gene flow between populations?• Are they exposed to high levels of
mercury?• Do they warrant conservation status?

RecommendationsRecommendations
• Monitoring protocol for Arctic- lek sites- transects
• Monitoring protocol for Fritillary- transects
• Determine survivorship and detectability• Determine host plant of Fritillary• Investigate shifts in timing of flight periods• Continue education efforts
