This polygon data set includes the protected areas of Canada that are
managed by national, state, provincial, or territorial authorities. As
defined by the International Union for the Conservation of Nature
(IUCN), a protected area is an area of land and/or sea especially
dedicated to the protection and maintenance of biological diversity, and
of natural and associated cultural resources, and managed through legal
or other effective means. The data set was assembled for the Commission
for Environmental Cooperation (CEC) from other public data sets
containing data on protected areas in Canada, Mexico, and the United
States. Protected area data was obtained from Natural Resources Canada
for areas in Canada; the National Commission of Natural Protected Areas
(CONANP) and the Nature Conservancy, Pronatura, and the National
Commission for Knowledge and Use of Biodiversity (CONABIO) for areas in
Mexico; and the Conservation Biology Institute (CBI) for areas in the
United States. This is an updated version of the March, 2008 data set.
