When it comes to nutrient loading to the Great Lakes, it’s usually phosphorus that makes headlines. The algal blooms that plague western Lake Erie and the “dead zone” that forms in Green Bay, for example, are linked to excessive phosphorus runoff from agricultural and urban lands. However, a recent study published in the journal Freshwater Science suggests that at least one important Great Lakes habitat may be affected by nitrogen loading just as much as it is by phosphorus.
Coastal wetlands of the Laurentian Great Lakes are critical habitats for many ecologically and economically important plants and animals. And like the rest of the Great Lakes, these habitats are susceptible to nutrient pollution from sources such as agricultural and urban runoff as well as discharges from sewage treatment facilities. Yet, there has been very little research devoted to understanding how coastal wetlands in the Great Lakes actually respond to nitrogen and phosphorus pollution. To read full article.
