The government says that a species of bird found primarily in Northwest Alberta is on the rebound after recovery efforts.

Populations of the trumpeter swan, which once ranged widely across North America, were depleted by the early 1900s by habitat destruction and hunting.

“I’m pleased the trumpeter swan can now be removed from the threatened species list. This success is a testament to the hard work, careful planning and commitment of Albertans to preserve our province’s biodiversity,” Robin Campbell, Minister of Environment and Sustainable Resource Development, said in a release.

The swan population has been helped considerably by active habitat management efforts, and the implementation of industrial land use guidelines surrounding breeding lakes.

Officials say that there are still challenges in the future of the species, especially concerning the use of habitats. For instance, little is known about the wintering habitats in the United States and with that left unknown, the conditions during that season could negatively impact the birds.

Four other species added to threatened species list

Unfortunately, one other bird species and three more fish species have been added to Alberta’s threatened species list.

They include:

The main reasons for the depletion of the populations of these species are habitat destruction and competition with other, non-native species.

Recovery plans for these species are currently being created, but Albertans are asked to avoid the areas where these animals live and breed.
