Wetlands are low-lying areas of land covered by water long enough to support aquatic plants and wildlife for part of their
Wetlands may be isolated on the landscape, or they may be inter-connected by complex hydrology.
Wetlands provide a range of functions and values.
Wetlands in Alberta are either peatlands or non-peatlands. Wetland types can be organized using various classification systems,
although no formal classification system has been adopted for use in Alberta. Wetlands can generally be classified as:
Bogs and fens (peatlands) or swamps
Shallow open water ponds (non-peatlands)
On the prairies, wetlands are predominantly the slough/marsh type. In the forested regions of Alberta, peatlands dominate.
Wetlands can also be characterized by their permanence. Wetland permanence is based on the period of time a wetland is inundated
by water. In Alberta, five wetland permanence types are found:
Wetland ownership is governed by the permanence of the wetland. The province does not claim ownership to the bed of wetlands
that are not reasonably permanent (i.e., ephemeral, temporary and seasonal wetlands).
Although the province does not claim all wetland beds, it does own all the water in wetlands through the Water Act and regulates
any activity that may affect them (e.g., drainage and infilling).

Alberta Wetland Policy
In response to the growing loss of wetlands on the landscape and the effect this may have on surface water management in
Alberta, Cabinet in 1993 approved the Interim Policy for "Wetland Management in the Settled Area of Alberta."
The policy identified as its goal that "the Government of Alberta is to sustain the social, economic and environmental benefits
that functioning wetlands provide, now and in the future".
The intent of the policy is further defined as follows, in descending order of preference:
To conserve slough/marsh wetlands in a natural state.
To mitigate degradation or loss of slough/marsh wetland benefits as near to the site of disturbance as possible.
To enhance, restore or create slough/marsh wetlands in areas where wetlands have been depleted or degraded.
