Paraquat Fact Sheet. Paraquat is a herbicide (chemical weed killer) used to control a very broad range of weeds (unwanted plants) in more than 100 crops, including cereals, oilseeds, fruit and vegetables, growing in all climates. Weeds shade crops, take their water and nutrients, and make harvesting difficult.araquat Fact Sheet.

1.1 DEFINING COASTAL AREAS. Coastal areas are commonly defined as the interface or transition areas between land and sea, including large inland lakes. Coastal areas are diverse in function and form, dynamic and do not lend themselves well to definition by strict spatial boundaries.he multifaceted approach to the management of coastal resources has become known as integrated coastal management (ICM). Pernetta and Elder (1993) have described it as meaning `the process of combining all aspects of the human, physical and biological aspects of the coastal zone within a single management framework'.
Wetland types found in coastal watersheds include salt marshes, bottomland hardwood swamps, fresh marshes, mangrove swamps, and shrubby depressions known in the southeast United States as pocosins.. Coastal wetlands cover about 40 million acres and make up 38 percent of the total wetland acreage in the conterminous United States. 81 percent of coastal wetlands in the conterminous United States are located in the southeast.
