This dataset is produced for the Government of Alberta and is available to the general public. Please consult the Distribution Information of this metadata for the appropriate contact to acquire this dataset. Trumpeter Swans (Cygnus buccinator) are sensitive to human disturbance, and human activity in breeding areas may cause abandonment, or decrease survival of eggs or cygnets. Trumpeter Swans are listed as a Threatened species under Alberta's Wildlife Act, and as such are afforded protection against hunting and the destruction of nests. This swan buffer layer includes all water bodies as of March 31, 2015 with confirmed breeding swan pairs (i.e., active nests or cygnets) as determined by swan surveys and incidental observations. The entire water body is considered a nesting site and was buffered by 500m and 800m to indicate the variable timing window setback options. Buffers are expressed as a computed 10 TM value. Sites not associated with waterbodies (lotic systems, unmapped wetlands, beaver ponds) were indicated by circular polygons (5m radius) and buffered by 500m and 800m. Accuracy of hydro layers is limiting, and it is recommended that all proponents measure setback distances from the high-water mark.
To provide the general public, industrial operators and government departments with information regarding the location of Trumpeter Swan waterbodies. Specific operating conditions apply to these zones. Land-use guidelines stipulate timing and setback conditions for all identified breeding locations.
Trumpeter Swan waterbody buffers have been endorsed by Alberta Environment and Parks, Government of Alberta. In February 2014, new buffers were added to reflect a newly identified breeding lake in 1-49-11-W5. There were five new lakes that were confirmed as breeding swan lakes in 2014 and subsequently added to the layer. In March 2015, it was discovered that about 50 lakes with confirmed breeding swans were inadvertently excluded from the layer. Therefore these lakes and associated buffers are now included.

Dataset copied (to create original dataset). In Feb 2014 polygons (500 m and 800 m buffers) added around new polygon in 1-49-11-W5.
Approximately 50 lakes with confirmed breeding swans were added to this dataset in March, 2015. To delineate these new waterbodies, the Base Waterbody Polygon Dataset was used. Multipart waterbodies were merged to represent a single feature (i.e., wetland) for breeding swans. For these additional lakes, 500m and 800m buffers were created.
