Abstract: The Alberta Merged Wetland Inventory depicts wetlands within the province of Alberta, Canada for the period 1998 to 2017 classified to the five major classes in the Canadian Wetland Classification System (CWCS). These five major classes include bog, fen, marsh, swamp and shallow open water. For the purposes of this inventory, shallow open water includes all open water. The Alberta Merged Wetland Inventory is a generalized, merged product of 35 component wetland inventories that utilized different types of source data from different years, different data capture specifications and different classifications. Considerable variation in the level of detail and accuracy is present in this dataset. Accuracy assessments have been included where available but it should be noted that the geoprocessing applied to the data may have introduced additional error. Note that the Alberta Merged Wetland Inventory product replaces the previously released Alberta Merged Wetland Inventory from October 23, 2018. The funding partners for the component inventories include: Ducks Unlimited Canada; Ducks Unlimited Inc.; Government of Alberta (Environment and Parks); United States Forest Service (USFS); United States Fish and Wildlife Service (USFWS); North American Waterfowl Conservation Act (NAWCA); The PEW Charitable Trusts; Canadian Boreal Initiative; Alberta-Pacific Forest Products Inc. (ALPAC); Environment Canada; Canadian Space Agency; Lakeland Industry and Community Association (LICA); Imperial Oil Resources; Shell Canada; Suncor Energy Foundation; Weyerhaeuser Company Limited; Encana Corporation and Parks Canada (Wood Buffalo National Park). Purpose of this dataset: To identify and describe the current coverage of wetlands within Alberta to the level of the five major Canadian Wetland Classification System classes. This information is used to evaluate the status of wetlands at a regional level. The wetland inventory dataset is not intended to replace site specific or local information to describe wetland type, area and location.

Abstract:
The Alberta Merged Wetland Inventory depicts wetlands within the province of Alberta, Canada for the period
1998 to 2017 classified to the five major classes in the Canadian Wetland Classification System (CWCS).
These five major classes include bog, fen, marsh, swamp and shallow open water. For the purposes of this
inventory, shallow open water includes all open water. The Alberta Merged Wetland Inventory is a
generalized, merged product of 35 component wetland inventories that utilized different types of source data
from different years, different data capture specifications and different classifications. Considerable
variation in the level of detail and accuracy is present in this dataset. Accuracy assessments have been
included where available but it should be noted that the geoprocessing applied to the data may have
introduced additional error. Note that the Alberta Merged Wetland Inventory product replaces the previously
released Alberta Merged Wetland Inventory from October 23, 2018. The funding partners for the component
inventories include: Ducks Unlimited Canada; Ducks Unlimited Inc.; Government of Alberta (Environment and
Parks); United States Forest Service (USFS); United States Fish and Wildlife Service (USFWS); North American

Supplemental Information:
Additional information on the source image type, source image date, image resolution, inventory system and
minimum mapping unit can be found in the associated Alberta Merged Wetland Inventory Status feature class.
The Alberta Merged Wetland Inventory Index feature class captures the extent of the inventory area. The
Alberta Merged Wetland Inventory feature class can be related to the information in the Alberta Merged
Wetland Inventory Status feature class using EXTENT as the common field.
All of the polygons have been assigned both a CWCS class and an extent. The extent identifies the component
wetland inventory project area. At the present time, wetland data are not available for the entire province.
There are data gaps along the eastern slopes. An overedge exists along portions of the provincial boundary.
There are three classification systems utilized by the 35 component inventories. These include: 1) Ducks
Unlimited Canada (DUC)-Boreal Enhanced Wetland Classification System (EWC): Landsat 5 and 7 ETM+ and Landsat
8 OLI and Sentinel-2 imagery were used to capture and classify wetlands to DUC's EWC system (up to 19
detailed wetland classes). The hierarchical classification system contains a class level, analogous to the
CWCS class level, which is subdivided into the EWC minor level. The EWC minor level contains information on
the dominant vegetation (i.e. graminoid/shrubby/treed). An accuracy assessment derived from field sites is
available for all inventory projects. The minimum mapping unit of the inventory is 0.09 ha and 0.01 ha.

Statement:
The original data that were captured at the detailed mapping level are distributed by Ducks Unlimited
Canada. 2) SPOT (Systeme Pour l'Observation de la Terre) Grassland Vegetation Inventory (GVI) Lentic
Classification: SPOT 4 and 5 MSS imagery was used to capture and classify wetlands to Alberta
Environment and Parks GVI standard. The GVI classifies lentic wetlands using a modified Stewart and
Kantrud approach that identifies wetlands based on site types and permanence. The SPOT-GVI lentic
wetlands were reclassified to the five classes associated with the CWCS major level. The minimum mapping
unit of the inventory is 0.04 ha. 3) High-Resolution: Stereo models of various scales were used to
capture and classify wetlands to a minimum mapping unit of 0.02 ha and 0.1 ha. These wetland data were
either crosswalked or captured directly into the National Wetlands Data Model, Alpha Edition 2010. As
such, the base data is compliant with the Canadian Wetland Inventory (CWI) standard. The CWI attributes
were generalized to include five classes of the CWCS major level, the remaining CWI attributes were
excluded from the Merged Alberta Wetland Inventory. There are two associated feature classes: the
Alberta Merged Wetland Inventory Status and the Alberta Merged Wetland Inventory Index. The extent of
the wetland inventory is captured as the Alberta Merged Wetland Inventory Index feature class and
information on the component wetland inventories is described for each project area within the Alberta
Merged Wetland Inventory Status feature class.
