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 fromrepparttar 146913 Alaskan coast to Mexico. It loves to eat fish. It tends to live in a freshwater habitat.

Inrepparttar 146914 1970ís, it was nearly wiped out from existence when its habitat was loaded with toxic chemicals. With very little control withrepparttar 146915 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 realizerepparttar 146916 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.

Inrepparttar 146917 early 1970ís, there were about 130 remaining. Since thenrepparttar 146918 cormorant population exploded to nearly 40,000 pairs!

Withrepparttar 146919 huge increase ofrepparttar 146920 cormorant, fishing sportsmen are saying they are excessively eatingrepparttar 146921 game fish inrepparttar 146922 Green Bay, Wisconsin area waters. Particularlyrepparttar 146923 Yellow Perch. Environmentalists claim that invasive zebra muzzles and white perch are also taking a toll on Yellow Perch. Alsorepparttar 146924 increase of game fish like walleye is consuming their share. Becauserepparttar 146925 cormorant are protected byrepparttar 146926 Migratory Bird Treaty Act, a federal permit had to be obtained in 2004 to try to controlrepparttar 146927 birds inrepparttar 146928 Green Bay area waters. A total of 436 cormorants were killed in 2004. They all had fish in them from eating according torepparttar 146929 officials. (What were they expecting from a fish eating bird, apples or oranges?)

The many uses ofrepparttar 146236 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 sellrepparttar 146237 development torepparttar 146238 City Council withrepparttar 146239 consideration of recent changes ofrepparttar 146240 Department of Natural Resourceís stormwater requirements.

According to EPAís National Water Quality Inventory: 2000 Report, prepared under Section 305(b) ofrepparttar 146241 Clean Water Act, urban stormwater runoff and discharges from storm sewers are a primary cause of impaired water quality inrepparttar 146242 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 preventrepparttar 146243 transportation of pollutants to Wisconsinís water resources via stormwater runoff.

Part ofrepparttar 146244 requirements of WPDES isrepparttar 146245 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 releaserepparttar 146246 stormwater back intorepparttar 146247 wetlands throughrepparttar 146248 natural soil filtration. Traditional curb and gutter generally takes allrepparttar 146249 water collected and dumps it intorepparttar 146250 rivers without natural or synthetic filtration.
