Modernization of sugar cane cultivation began when 16 whole-stalk harvesters were successfully used to harvest cane in Louisiana in 1938. Labor shortages caused by World War II led to the need for increased mechanization and by 1946 the number of whole-stalk machines operating in Louisiana jumped to 422, harvesting 63% of the state’s crop.

How has the cane toad changed the ecosystem of Australia?
Cane toads have been linked to the decline and extinction of several native predator species in the Northern Territory and Queensland, including the northern quoll. Their toxin is strong enough to kill most native animals that normally eat frogs or frog eggs, including birds, other frogs, reptiles and mammals.
How did cane toads become an invasive species?
Cane toads (Bufo marinus) were a complete failure at killing Australia's sugar cane-ravaging beetles. Instead of controlling the pests, the toads have become pests themselves. A healthy sex drive and a concealed deadly chemical defense system have transformed them into one of the world's top 100 invasive species.
What frogs are poisonous to dogs in Florida?
Pet owners need to keep an eye out for bufo toads as they surge in numbers. Bufo toads are not native to Florida, but they are moving into the area by the thousands and can pose a significant threat to pets. The toads release a toxin that when consumed by a dog, can cause seizures and possibly be deadly.
Are there poisonous frogs in Hawaii?
Our green and black poison dart frogs are “local” specimens, found in Manoa valley. Green and black poison dart frogs were introduced by the Territory of Hawaii in 1932 for mosquito control.

When were cane toads introduced?
Cane toads were introduced to Australia in 1935 Why were they introduced in the first place?
