Canadian IBA Polygon layer
Entry ID: Canada_BirdStudiesCan_IBA

[ Update this Record ]

Summary
Abstract: This layer represents *generalized* boundaries of Important Bird Areas (IBA) in
Canada. IBAs, in Canada and elsewhere, are evaluated and designated on the
basis of internationally established criteria. The polygons contained in the
dataset meet these criteria and are therefore deemed significant at the
national, continental, or global level. In Canada, IBAs are not legally
recognized entities and therefore do not have any regulatory status.
Nevertheless, they are extremely useful for conservation planning for birds.

Polygon boundaries were digitized on-screen in ArcView GIS 3.2 by using NTDB
1:50K or 1:250K digital layers for reference. If NTDB coverage was not
available (e.g., far north), the Digital Chart of the World (1:1M) was used.
The boundaries of IBAs in this dataset are intentionally generalized to reflect
the importance of the surrounding ecosystem on the values present within IBAs.
For example, small islands supporting colonies of seabirds might be buffered by
1 or 2 km to form an IBA. Boundaries for a very small minority of IBAs were
available in paper form as part of IBA conservation plans that had been
developed previously. In such cases, we visually estimated their boundaries
against the NTDB or other base layers. Many IBAs are already recognized as
other types of protected areas, e.g., National Wildlife Areas, National and
Provincial Parks, Migratory Bird Sanctuaries, conservation reserves, and so on.
In these cases, we used digital boundaries from other sources (e.g. WWF
Canada's Designated Areas Database, Environment Canada's Canadian Conservation
Areas Database) as reference points when digitizing IBA boundaries.To provide
the conservation community with a national scale polygon dataset for use in
bird conservation planning.
