Important and often unappreciated lands.
It is the transition zone between truly aquatic habitat and terrestrial habitat.
The problem of defining a wetland has become entangled in politics as well as science.
High economic stakes
Very nature of being a transitional zone
Currently, estimates indicate about 6.4% of land globally is wetland
Over the past 250 or so years, 53% of US wetlands have been lost due to human activities
Most US wetlands are in Alaska (approx. 70%) with the remainder in the lower 48 states
Of the approx. 42 million acres in the lower 48, about 80% is inland and about 20% is coastal
The wetlands of the Carboniferous
Period generated most of the fossil fuel upon which we now rely
1.
Shallow water or saturated soils at least at some time during the year
2.
Accumulate slowly decomposing organic matter
3.
Have plants and animals typically adapted to saturated conditions
1.
They are purifiers – “kidneys of the landscape”
2.
Prevent floods
3.
Protect shorelines
4.
Recharge aquifers with “purified” water
5.
Important as wildlife habitat

The U.S. Fish and Wildlife Service estimates that up to 43% of the federally threatened and endangered species rely directly or indirectly on wetlands for their survival

The United States Supreme Court recently affirmed the authority of the Army Corps of Engineers to require a permit for “deep ripping” activities. The defendant, Angelo
Tsakopoulos, began “deep ripping” his ranch in 1993 without a permit. “Deep ripping” is a farming practice which uses four- to seven-foot prongs to churn the soil behind the tractor and prepare the soil for orchards and vineyards. Many of the areas chosen by Tsakopoulos contained protected swales, sloped wetlands which filter water and minimize erosion. The
Army Corps of Engineers and the EPA informed Tsakopoulos that he needed a permit to continue, and when he failed to cease activities, issued an administrative order against him.
Tsakopoulos filed a lawsuit in the United States District Court for the Eastern District of California challenging the authority of the Corps and the EPA. Tsakopoulos was fined $500,000 and required to restore four acres of wetlands.
Neb.USA - Environmental Protection Agency cited two western Nebraska landowners for violating the Clean Water Act.Wayne
Hansmeier and the Kingsley Cattle Company are ordered to pay $20,000 and replace lost wetland area.Hansmeier diverted Whitetail
Creek, a tributary of the North Platte River.The
Kingsley Cattle Company dug a new channel for the creek and filled about 1,200 feet of the creek bed and wetlands in Spring of 2003.
Want to do this just as we have for forests, deserts, grasslands, etc., scientifically
This is called wetlands delineation or wetlands determinations
Determinations - is a wetland present or not
Delineation - where exactly is the boundary
1.
What if water is only present part of the year?
2.
Not all “wetland organisms” are strictly limited solely to “aquatic” habitats
3.
Wetlands may be large or small and very different because of size or location
4.
Any different wetlands affected differently by outside influences
Most definitions will have the following components to some degree or another
1.
Wetlands are distinguished by the
“presence” of water either at the surface or in the root zone
2.
Wetlands often have unique soil conditions that differ from adjacent upland soils
3.
Wetlands support vegetation adapted to wet conditions and lack those intolerant of flooding
