Context

• Conflicts with mountain lions increasing

– Mountain lion populations increasing

– Human development intruding into lion habitat

– Lions feeding closer to residential areas

– Management actions scrutinized in popular presswhen a human is injured or killed

• Important to evaluate attitudes to mountain lionsand acceptability of alternative mgmt. actions

Page 3: Understanding Human-Mountain Lion Management Strategies Using PCI Jerry J. Vaske Rebecca Howe Michael J. Manfredo Colorado State University Fort Collins,

Hypotheses

H1: As severity of human–lion interactions increases,

acceptability of destroying a lion increases

H2: As severity of the human–lion interactions increases,

consensus regarding destroying a lion decreases

Page 4: Understanding Human-Mountain Lion Management Strategies Using PCI Jerry J. Vaske Rebecca Howe Michael J. Manfredo Colorado State University Fort Collins,

Hypotheses

H3: Individuals with positive attitudes toward lions will be less accepting of destroying them regardless of severity of human–lion interaction

H4: Individuals with negative attitudes toward lions will have more consensus toward destroying them as severity of human–lion interaction increases

• n = 2,668

• Two random sample populations– Denver metro area (response rate = 50%)

– Denver foothills (response rate = 67%)

• Non-response phone interviewNo statistically significant difference

• As severity of human–lion interaction increases:

– Average acceptability of lethal control increases– Consensus for lethal control decreases

• Those with positive attitudes (the majority) are always less accepting of lethal control

• Consensus for lethal control varies by attitude– Positive attitude – consensus decreases with severity– Negative attitude - consensus increases with severity
