Earth Day began on April 22, 1970 and started the modern environmental movement. One of the main focuses of Earth Day is the loss of species and was a factor in the initiation of the Endangered Species Act. There are several situations that affect this such as loss of habitat and invasive species.
Wisconsin has a diverse landscape that includes hardwood forests, prairie, a complex river system and it is bordered by Lake Superior on the north and Lake Michigan on the east. Thus affording a diverse population of species, some rare.
The Karner blue butterfly feeds on lupine that grows in the dry areas of Wisconsin. The Kirtland’s warbler is listed on the endangered species list and is now breeding in Wisconsin’s young jack forests. The leafhopper has only been seen four times in the Wisconsin prairies since 1994.
In many situations these populations are threatened due to the increased human population of the state. The growing cities encroach on the wild habitat splintering the areas into islands of habitable areas for the wild population.
Invasive species have threatened the native animals causing a reduction in their population. Fire restrictions have also played a part in the natural order. It is an essential role in the health of the environment.
Wisconsin is a key area in the well-being of the environment and with the help of the state agencies the wild animal inhabitants are carefully monitored. Milwaukee area residents can volunteer in many of these programs.
