Extent of Canada's wetlands indicator: data sources and methods, chapter 3


3. Data

3.1 Data sources

Because no national wetland monitoring system exists, data from multiple sources were combined. These include:

Ecozones

Canadian Council on Ecological Areas (2014) Canada Ecozones V5b.

3.2 Spatial coverage

National.

3.3 Temporal coverage

Circa 2000.

3.4 Data completeness

Completeness of data varies geographically, with the underlying data source (see individual data sources in section 3.1 for details). Data from sources including provincial, territorial and federal governments, as well as non-government organizations, were considered for inclusion. A minimum mapping unit of one hectare or less was required.
