•Largest frog in US
•Introduced to SW in early 1900’s
as food source
•Voracious predators
•Ability to travel long distances
•High fecundity
•Highly adaptable
Why is the Bullfrog considered
‘Biological Pollution’?
•Rapid predation of native species
•High competition as riparian predator
•Highly mobile conduit for fatal disease
(Chytrid fungus)
•Eradication/control very expensive, and
inefficient
Solutions:
Education/Prevention-increase awareness on issue,
