Swamps are most common in temperate areas of Canada.

A swamp has open surface water. They are associated with rivers, lakes and waterways. They are not as wet as marshes or fens, however they still hold a significant amount of water during dry seasons. Swamps are nutrient-rich and productive.
Swamps often have open surface water, and so trees and large shrubs need to be tolerant of these conditions. The soils are constantly wet and it is the aerated (or partly aerated) soils above the water that is available for root growth.
Coniferous or deciduous forest or tall thickets are common types of swamps found in Muskoka.
Trees common in northern swamps include:
Swamps are very productive habitats and home to a wide variety of species.
Snakes are at home in a swamp because of their amazing ability to swim. Dead and fallen trees found in swamps provide habitat for an abundance of wildlife. Woodpeckers look for insects in the rotting wood and make their new home in a soft tree trunk, while ducks and Great blue herons build their nest around the trees.
What are Wetlands?
Wetlands are defined as lands that are saturated with water long enough to cause the formation of waterlogged (hydric) soils and the growth of water-loving (hydrophytic) or water-tolerant plants.
Wetlands are Important
Surface water runoff may contain sediments, excess nutrients, viruses and pathogens and/or a variety of chemicals. A wetland acts like a filter to remove sediments, absorb nutrients and biologically change many chemicals into less harmful forms.
Significant Wetlands and the Ontario Wetland Evaluation System
Provincially Significant Wetlands are those areas identified by the province as being the most valuable. They are determined by a science-based ranking system known as the Ontario Wetland Evaluation System.
Ontario is home to approximately 24% of Canada's wetlands and 6% of the world's wetlands. Estimates of wetland extent in Ontario range from 24 million to 29 million hectares, or 22-27% of the area of the province.
Wetlands in a Watershed Context
A watershed is an area of land that drains into a common body of water and involves water and any other natural feature or function that affects or is affected by water.
