Wide variation in awareness of different endangered species

Differences in awareness may be cumulative effect of: • Body size (role in food web)• Evolutionary similarity• Geographic proximity• Visible distinctiveness

What are the possible policy responses?
Work with other countries to manage species and beneficiaries
Recognize importance of awareness and information
Develop methods to value and manage “low awareness” species
Look at values around status designation thresholds
Shift how priorities are set
