Manatee
Fact - Native to Florida?
One of the more persistent misconceptions
appearing in "Letter to the Editor" columns and comments in
response to Service proposals includes the idea
that the Florida manatee is an exotic, introduced species.
This is not the case.
One source of the persistent "non-native
species" myth may come from a study conducted in south Florida
in the 1960's. This study assessed the effectiveness
of Florida manatees as a means to control exotic aquatic
plants and was based on similar work conducted with Antillean
manatees in Guyana. While Antillean manatees were
never brought to Florida for the purposes of the study, the study
generated a lot of publicity and confusion
about non-native manatees, exotic plants, and Florida's manatees.
The
Florida manatee is one of two sub species of the West Indian manatee. West Indian manatees are a species
known to range
from Brazil north to Mexico and the southeastern United States, including the Caribbean islands.
This species includes
two sub species, the Antillean manatee and the Florida manatee. The Antillean manatee
ranges from Brazil to Mexico, including
the Caribbean islands. The Florida manatee is found in the southeastern
United States, with the core of its range here
in Florida.
Manatees are well represented in Florida’s fossil record. Their remains date back to prehistoric times
and
they are one of the more common vertebrate fossils known from ancient marine deposits. Manatee remains are
also
found in Native American rubbish heaps in Florida, sites that pre-date the arrival of the early Spaniards.
The early
colonists described how these natives hunted the manatee and were quick to appreciate the
intrinsic value of the species.
In
the seventeenth and eighteenth centuries, papal decrees and British law sought to dictate who, when,
and where these
animals could be killed. In 1893, the state of Florida passed legislation that prohibited
killing manatees. The West
Indian manatee, including both Florida and Antillean sub species, was
further protected in 1972 and 1973 with the passage
of both the Federal Marine Mammal Protection Act and
the Endangered Species Act, respectively. Florida followed suit,
further protecting the Florida manatee
through state endangered species legislation and subsequently through the Florida
Manatee Sanctuary Act in 1978.
The Florida manatee is a significant part of the State's natural, cultural, and historic
heritage. By working together,
we can see to it that manatees are a continuing part of our heritage and our future.
