Cormorant Overabundance in WisconsinWritten by Kevin Doberstein
Article intro: In 1970’s, Cormorant was nearly wiped out from existence when its habitat was loaded with toxic chemicals. With very little control with use of toxic chemicals in that decade. The wildlife environment was being contaminated. The bald eagle was also nearly wiped out from eating contaminated food (fish) during this period.

Cormorant Overabundance in Wisconsin by Kevin Doberstein Copyright Protected 2005 What is a Cormorant? The double-crested cormorant is just a bit more than two feet long on average with a wingspan of about four feet. Its color is dark brown to black feathers and has a long hooked bill. The males and females look quite similar. They are a migrating traveler from Alaskan coast to Mexico. It loves to eat fish. It tends to live in a freshwater habitat. In 1970’s, it was nearly wiped out from existence when its habitat was loaded with toxic chemicals. With very little control with use of toxic chemicals in that decade. The wildlife environment was being contaminated. The bald eagle was also nearly wiped out from eating contaminated food (fish) during this period. Finally people started to realize fact that dumping these chemicals in mother earth was not a good idea. Now we have to work to clean father sky from acid rain. Rebounding Cormorant. In early 1970’s, there were about 130 remaining. Since then cormorant population exploded to nearly 40,000 pairs! With huge increase of cormorant, fishing sportsmen are saying they are excessively eating game fish in Green Bay, Wisconsin area waters. Particularly Yellow Perch. Environmentalists claim that invasive zebra muzzles and white perch are also taking a toll on Yellow Perch. Also increase of game fish like walleye is consuming their share. Because cormorant are protected by Migratory Bird Treaty Act, a federal permit had to be obtained in 2004 to try to control birds in Green Bay area waters. A total of 436 cormorants were killed in 2004. They all had fish in them from eating according to officials. (What were they expecting from a fish eating bird, apples or oranges?)

The many uses of Functional Wetland. By Kevin Doberstein Copyright 2005 Nature Boy Natural Images In a recent City council meeting that was held in a small city in northern Wisconsin, a developer was trying to present a plan. This development plan included approximately 16.4 acres of wetland. He was trying to sell development to City Council with consideration of recent changes of Department of Natural Resource’s stormwater requirements. According to EPA’s National Water Quality Inventory: 2000 Report, prepared under Section 305(b) of Clean Water Act, urban stormwater runoff and discharges from storm sewers are a primary cause of impaired water quality in United States. Wisconsin Department of Natural Resources answer was a program called Wisconsin Pollutant Discharge Elimination System (WPDES). The ultimate goal of WPDES is to prevent transportation of pollutants to Wisconsin’s water resources via stormwater runoff. Part of requirements of WPDES is replacement of traditional curb and gutter that is typical with street construction to be replaced with shallow grass swales and retention ponds. The concept of this plan is to slowly release stormwater back into wetlands through natural soil filtration. Traditional curb and gutter generally takes all water collected and dumps it into rivers without natural or synthetic filtration.
