Bison Return to Canada After an Absence of 100 years
On 1st February, 16 Bison were reintroduced back in Canada’s oldest National Park to restore the environment. Ellen Daugherty reports
Reintroductions of wild species are rapidly becoming a hot topic in environmental conservation, with the likes of wolves and lynx being suggested for reintroduction into Scotland. Despite the obvious controversy surrounding the issue, reintroduced species can rejuvenate the environment, especially if the species used to exist in the area but went extinct due to human exploitation. If a reintroduced species is a keystone species, it has the capability to exert a huge amount of positive influence on its surroundings.

This is the main idea behind reintroductions, to relocate a once native species, that will cause a plethora of changes in the environment and restore the ‘true’ landscape. The bison were relocated to the Banff national park in Alberta, Canada, as a keystone species for that environment. It has been said this reintroduction will lead to a return to the full biodiversity of the national park, with natural processes within the ecosystem being restored.
At the moment the 16 new individuals have been confined to a 1200km2 enclosed pasture, until 2018, so their health and progress can be measured while the environment is still new to the small population. Hopefully if this preliminary period is successful, then the bison can have free range over the whole site and establish a wild population once again in the park.

Reintroductions are an important process to consider, when wanting to restore a certain environment, as it has huge potential for a knock on effect to all aspects of the ecosystem. More research is needed into how this could be implemented into UK landscapes, using the Scottish Highlands as a key area for potential reintroductions. Who knows, perhaps one day wolves, lynx and bison will roam across the country once again!
