Canadian environmental sustainability indicators : extent of Canada's wetlands. : En4-144/67-2025E-PDF

"Wetlands are among the most important ecosystems on the planet. They provide vital habitats for wildlife, filter pollutants, offer flood protection and drought mitigation, absorb and store carbon, and are important cultural sites for many Canadian communities. Wetlands are also one of the Earth's most endangered ecosystem types. This indicator reports the current known extent or area of land in Canada covered by wetlands and establishes a baseline to measure future changes over time in Canada's wetland extent"--Extent of Canada's wetlands, page 5.
