AbstractWetlands are lands permanently or temporarily submerged
or permeated by water, and characterized by plants adapted to saturated-soil
conditions. Wetlands are the only ecosystem designated for conservation
by international convention because they absorb the impact of hydrologic events,
filter sediments and toxic substances, supply food and essential habitat for
many species, provide products for food, energy, and building material, and
are valuable recreational areas. Some wetlands help recharge groundwater, while
others receive groundwater discharge. Wetlands are vulnerable to climatic variations
and extreme events. Wetlands occur across most of Canada. Their location usually
depends on local factors of drainage, topography, and surface material.
