Alaksen National Wildlife Area (NWA) is located in British Columbia. The site supports an incredible diversity and number of birds each winter. It is open to visitors from 9 am until 3:30 pm, Monday to Friday.


Alaksen NWA is part of the Fraser River delta. The delta has an area of 67,000 hectares (ha), including the NWA’s 349 ha. The delta is an important migration stop-over, and a wintering area for a large number of migratory birds along the Pacific coast. It contains:

  • estuarine habitats
  • remnant wetlands
  • riparian forests
  • agricultural areas
  • urbanized zones

The delta attracts up to 1.4 million birds migrating from Siberia to South America each year. No other site in Canada supports such a diversity and number of birds in winter. No comparable site exists along the Pacific coast between California and Alaska.

Snow geese in concentrated flocks are a spectacular sight at the NWA. The numbers exceed 25,000 beginning in October. They are abundant in upland fields during both high tide and inclement weather events. It is also common to see flocks of 15,000 or more dabbling ducks making use of the NWA. The most plentiful are:

Alaksen NWA was established in 1976. The NWA mainly consists of four former deltaic islands. Causeways and dykes joined the islands together in the earlier part of the 20th century. Alaksen NWA contains habitats and wildlife found on the Fraser River Delta. Known for its wildlife, Alaksen NWA is recognized as:

A section of Alaksen NWA overlaps with the George C. Reifel Migratory Bird Sanctuary (MBS) as well.

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 their 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 activities are prohibited. However, some activities may be authorized through public notice or the issuance of permits as long as they are consistent with the management plan goals for the NWA. For more information, consult the NWAs Management and Activities section.

More information on access and permitting for Alaksen NWA can be obtained by contacting the Environment and Climate Change Canada regional office.

The British Columbia Waterfowl Society manages the George C. Reifel Migratory Bird Sanctuary (MBS) under an agreement with Environment and Climate Change Canada. The public can visit daily from 9am until 4pm. The rest of Alaksen NWA is open from 9 am until 3:30 pm, Monday to Friday.

Agricultural activities are permitted within Alaksen NWA. This type of management provides high quality habitats for waterfowl. Agricultural activities also preserve habitat for the conservation of other wildlife.

Note: Do not bring pets to the sanctuary.
