REINTRODUCTIONS - Can they work?
Famous success stories

Golden lion tamarin1970’s 200147 captive bred releases2001 - 1000% wildborn now 88%
REINTRODUCTIONS - Will they work?
Wolves in Yellowstone
Cause of extirpation
Human hunting
Reintroduction
1995-97 41 individuals
Current population in YNP - 271+
Prospects No longer “endangered”
REINTRODUCTIONS - Will they work?
The Guam rail
Cause of extirpation
brown tree snake (introduced)
Reintroduction
Rota - predator free island Guam - 60 ha fenced area
Prospects on Guam - not good
REINTRODUCTIONS - Will they work?
MOST IMPORTANT CONSIDERATION
What caused extirpation in the first place?
Has that threat been reduced/eliminated
