Distribution
The indigenous distribution of Pomacea haustrum is Bolivia, Brazil and Peru in South America.
The nonindigenous distribution includes the United States: Loxahatchee National Wildlife Refuge waters in Palm Beach County, Florida. Pomacea haustrum were discovered in the late 1970s in Palm Beach County Florida, and have not spread appreciably in 30 years. This is the only known area where this species is established in the United States. The initial introduction in the United States was probably from aquarium release, aka "aquarium dumping". Pomacea haustrum is currently of relatively minor concern in the U.S., given its failure to spread beyond Palm Beach County after 30 years or more in Florida. However, many species have maintained limited distributions, sometimes for decades, before becoming invasive.

Famous quotes containing the word distribution:
“My topic for Army reunions ... this summer: How to prepare for war in time of peace. Not by fortifications, by navies, or by standing armies. But by policies which will add to the happiness and the comfort of all our people and which will tend to the distribution of intelligence [and] wealth equally among all. Our strength is a contented and intelligent community.”
—Rutherford Birchard Hayes (1822–1893)
“The question for the country now is how to secure a more equal distribution of property among the people. There can be no republican institutions with vast masses of property permanently in a few hands, and large masses of voters without property.... Let no man get by inheritance, or by will, more than will produce at four per cent interest an income ... of fifteen thousand dollars] per year, or an estate of five hundred thousand dollars.”
—Rutherford Birchard Hayes (1822–1893)
“There is the illusion of time, which is very deep; who has disposed of it? Mor come to the conviction that what seems the succession of thought is only the distribution of wholes into causal series.”
—Ralph Waldo Emerson (1803–1882)
