Canadian Wetland Inventory

The Canadian Wetland Inventory (CWI) was established in 2002 by Ducks Unlimited Canada, Environment Canada, the Canadian Space Agency and the North American Wetlands Conservation Council. The CWI Progress Map displays wetland areas across Canada. It’s used to assess future wetland loss, degradation and restoration.

The Canadian Wetland Inventory (CWI) was established in 2002 by Ducks Unlimited Canada, Environment Canada, the Canadian Space Agency and the North American Wetlands Conservation Council. As a resource, the CWI is valuable for a number of other purposes. It helps to:

• Focus conservation, restoration and wetland monitoring programs
• Assess changes in wetland abundance and classification in relation to climate change concerns
• Assist industry, governments and conservation groups to develop land-use policies and protocols
• Measure performance of those policies and protocols towards landscape sustainability objectives

CWI Data Model
The CWI is a national approach to establish a consistent framework to map wetlands, in order to build Canada’s capacity to respond to local, regional, national and international drivers. The CWI encourages consistent interpretations by communities of interest through a common data structure and classification system. Based on The Canadian Wetland Classification System, the Canadian Wetland Inventory data model divides wetlands into shallow water, marsh, swamp, fen, and bogs.

CWI Progress Map

The CWI Progress Map displays wetland areas across Canada. It’s used to assess future wetland loss, degradation and restoration.

This interactive map displays CWI-compatible wetland inventory areas that have been completed or are in progress across Canada. This application also visualizes detailed wetland polygons and information for certain areas where wetland inventory data have been made available.

The map has been compiled to make wetland information readily available for a broad range of users. Source and partnership information for the various wetland inventory datasets have been provided within the map application.

License License used to access the dataset.	The purpose of the Canadian Wetland Inventory (CWI) Progress Map is to display CWI-compatible wetland inventory areas that are completed or in-progress across Canada. This map application also permits the visualization of detailed wetland polygons and attribute information for certain areas where wetland inventory data have been made available. Data used to build the CWI progress map have been compiled from CWI partners with the intent of making wetland information readily available to a broad range of users in the form of an interactive map. Source and partnership information for the various wetland inventory datasets have been provided within the map application. DUC makes no guarantee as to the validity of the wetland maps and data represented and neither DUC nor the CWI partners assume legal liability or responsibility for any errors or misuse of the information provided. By accessing this map application, you hereby release DUC and all the CWI partners from any and all responsibility and liability associated with its use.
