The largest herd of adult male bison was registered in Bialowieza Forest. In the herd of over 150 head scientists counted 19 wild bulls. Previously, this figure did not exceed 13. It is known that adult males prefer to live separately during the rutting season.
Bison experts were surprised to see that the forest giants prefer agribusiness fields to numerous feeders, especially if these fields are sown with winter rapeseed. Unfortunately, it was not without losses this winter: two young bison did not survive the cold season.
Alexei Bunevich, national park Bialowieza Forest:
Small bison born in November or December... Many of them perish. The fact is that they are still weak bison. They migrate from summer to winter flocks, pass drainage canals. Adult bison go and, accordingly, small bison have to survive those colds and cold water too. And most die of hypothermia or pneumonia.
In total, 58 bison were born in 2016 in the forest. 80% of them were born in a favorable period - spring and summer, which allowed them to get a little bit stronger to survive the cold winter safely.
