Endangered
Species
Many native species, in Indiana and across the
globe, are disappearing quickly.
The species are categorized by the Indiana Department
of Natural Resources according to how few of them are left.
A species of concern is any species with known or
suspected problems of limited abundance or distribution in
Indiana; these species should be closely monitored. A species
becomes endangered when there are so few individuals
that the species could soon become extinct. Extirpation
means that the species has ceased to exist in Indiana. The
federal government can classify a species as extinct,
meaning that the species has ceased to exist in the wild.
In a study done in 2000 by the World Conservation
Union, 11,046 plants and animals were said to be "facing
a high risk of extinction in the near future, in almost all
cases as a result of human activities."
Extinction is a natural process that has been
accelerated by human activity. Increase in human population
has resulted in major habitat
destruction and fragmentation, over-fishing, introduction
of exotic species, poaching, and pollution.
Below is a table showing the number of species that are of
concern, endangered, or extirpated in Indiana. These species
may or may not be federally threatened, endangered or extinct.
To find a list of these species please visit the IDNR
Division of Fish and Wildlife Web Site.

The Indiana Department of Natural Resources (IDNR)
is acting upon these statistics. The state has restored three
previously endangered species—bald eagles, peregrine
falcons, and river otters—back to their natural habitat.
These species have now become more abundant in the state.
Bald eagle nesting sites increased from zero to twenty between
1989 and 2001. In 1995, river otters were very rare in Indiana,
but due to a four-year restoration program, they now occur
in thirty-five counties. At least eighty-three peregrine falcons
have fledged from Indiana nests since 1989, ranking Indiana
fourth among Midwestern states in falcon pairs and young produced.

Currently research is under way to restore several
more endangered species--such as Ospreys
and the Indiana bat. Several donation programs fund these
restoration projects, including the state income tax check-offs
created by the Indiana
Nongame and Endangered Wildlife Program (NEWP), which
allow tax-payers to donate part of their state tax refund
to this cause. NEWP programs involve research, habitat management,
public education, land acquisition and restoration projects.
