Tway National Wildlife Area

Tway National Wildlife Area (NWA), in Saskatchewan, is an important area for waterfowl and other species.

Description

Tway NWA lies in the Aspen Parkland Eco-region at the headwaters of the Carrot River, in central Saskatchewan. The marsh complex consists of managed wetlands surrounded by 96 hectares (ha) of rolling uplands covered by hayfields and trembling aspen forests. The marsh is a waterfowl staging area and a breeding area for:

Today, wetlands make up almost three-fourths of the area and waterfowl production has increased. Shorelines of the marshes support emergent plants like:

Previously cultivated land was seeded with smooth brome and alfalfa. Remaining natural vegetation in uplands consists of aspen groves and shrublands of:

Management

Under the Canada Wildlife Act, NWAs are protected and managed in accordance with the Wildlife Area Regulations. The primary purpose of NWAs is to protect and conserve wildlife and wildlife habitat. For this purpose and according to the legislation, all activities in a NWA that could interfere with the conservation of wildlife can be prohibited. 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 Tway NWA is not restricted and activities may be permitted in accordance with the conservation objectives of the NWA management plan. Any authorized activities are listed in Schedule I.1 of the Wildlife Area Regulations; signage is also posted at access points.

The management of Tway NWA focuses on water level manipulation. The goal is to sustain wetland habitats for wildlife through drought or dry weather. Maintenance of water level control structures is accomplished in cooperation with Ducks Unlimited Canada. The Canadian Wildlife Service manages haying or grazing of upland cover.

Few people use the NWA for bird watching, photography, or nature study. Tway NWA, however, provides opportunities for wildlife-oriented public activities which complement the conservation objectives of the NWA.

Authorized activities listed in Schedule I.1 of the Wildlife Area Regulations for Tway NWA, include:

  1. wildlife viewing
  2. hiking
  3. non-commercial berry picking
  4. non-motorized boat launching and boat landing
  5. non-motorized boating
  6. sport hunting — including with dogs off-leash when hunting migratory game birds — without a commercial guide, from half an hour before sunrise to half an hour after sunset, if the hunting is carried out
