Canada, a partner in NABCI, will
be using BCRs as a spatial framework for bird conservation for the next
three years, at which point the system will be re-evaluated and adapted as
required. For more information on the ecological features of Canadian BCRs,
click on a BCR of interest on the map.

Note
for GIS users:
A compressed ArcInfo
export file of North American BCRs is available
for downloading (approx. 5 MB). This file is compatible with
ArcInfo and ArcView (as well as other GIS programs supporting
the e00 format). ArcView users should use the Import71 utility
that is packaged with ArcView to access the BCR coverage. The
coverage is stored in geographic coordinates. Click
here to download an ArcInfo projection file containing
the parameters required to transform the BCR coverage from
geographic coordinates to projected coordinates (Lambert Equal
Area Azimuthal projection). The Lambert projection was used in
the maps shown here because it preserves shape and area
properties for features covering large expanses of latitude,
e.g., North America. This projection is recommended for
calculating area measurements, e.g., BCR area, provincial area.
