Raven Island National Wildlife Area

Raven Island National Wildlife Area (NWA), in Saskatchewan, is an important area for waterfowl and other birds.

Description

Raven Island National Wildlife Area (NWA) lies in the Aspen Parkland Eco-region in the southern part of Lenore Lake and the Lenore Lake Migratory Bird Sanctuary. It is around 140 kilometres (km) northeast of Saskatoon, Saskatchewan.

The lake is primarily an open water body with emergent aquatic vegetation limited to protected bays. It depends on runoff from many small creek channels in the area. The lake is subject to severe water level fluctuations. Low-lying grasslands and mudflats provide uncommon habitat that is ideal for nesting birds.

The NWA is joined to the mainland during periods of drought, when water levels drop in Lenore Lake. Trembling aspen and willow grow along the west side. Patches of rose and snowberry are scattered around the perimeter of the island. Half the island was previously cultivated land, but has been re-seeded to dense nesting cover. Stands of bulrush and some cattail and whitetop are found near the sheltered east shore.

Consequently, most NWAs are not accessible to the public and all other activities are prohibited in all NWAs. However, some activities may be authorized through Schedule I.1 of the Wildlife Area Regulations or the issuance of permits as long as they are consistent with the management plan goals for the NWA. For more information, consult the NWA Management and Activities section.

Access to Raven NWA is restricted. Activities, however, may be permitted in accordance with the conservation objectives of the NWAs management plan. Any authorized activities are listed in Schedule I.1 of the Wildlife Area Regulations; signage is also posted at access points.
