PRINCE ALBERT One of the last free-roaming plains bison herds in Canada is seeing signs of renewal after over a decade of population decline. The Sturgeon River Plains Bison Herd roams on the southwest side of Prince Albert National Park. The park has adjusted its monitoring methods over the years and has settled on observation to determine estimated populations every year, according to wildlife ecologist Digit Guedo. She said this year’s aerial survey and counts from people on the land show a minimum population of 98 bison, but the herd is likely sitting at around 120 animals – that’s up from an aerial survey in 2016, which showed a minimum of 58 bison.
