Wetlands
The Wetlands are found all over the world, within almost every terrestrial biome from deserts to alpine tundra. A Wetland is described by the plant species that live in it.  If an area is wet enough for long enough to support a majority of plants that are adapted to wet conditions then you have a wetland.  Roughly the world's wetlands are believed to cover 7 to 9 million kilometres, (or about 4 to 5 miles), of the planet (environmnt.gov.au 2009) . That is roughly 4 to 6 percent of the earth's surface. Out of this, 56% of wetlands are found in tropical or subtropical regions. Wetlands exist in every country and every climate throughout the world. Wet lands can be divided into sub categories such as Marches, Swamps, Bogs and Fens all of which can be classified as a category of a wetland biome. Since Wetlands are spread out throughout the world so much I will mainly concentrate my research on Canada’s wetlands. Wetlands do not have to be a specific type of water due to its ability to adapt and filter allowing for fresh and salt water Wetlands. Temperatures vary greatly depending on the location of the wetland. Many of the world's wetlands are in temperate zones (midway between the North and South Poles and the equator). In these zones, summers are warm and winters are cold, but temperatures are not extreme. However, wetlands found in the tropic zone, which is around the equator, are always warm. The rough average is 40-80 degrees; this average was present from the environmental Canada website (http://www.ec.gc.ca). Once again this average depends on where the wetland is located and can vary on the biome next to it. The growing season for wetlands are normally 365 days which is equivalent to a full year, in Canada the growing season is not 365 due to winter conditions and often slows if not completely halter the growing. Henderson Lake, British Columbia, has the greatest average annual precipitation in Canada – 6,655 millimetres. In contrast, Eureka, in...
