Abstract
European Bison population in Europe decreases due to the habitat damage, deforestation and lack of
food. The males in the wild are usually most reproductive at an age of 6 to 12 years. As to females, they
normally reach maturity by the age of 3 years. Reproduction intensity depends much on the amount and
quality of food. The reproduction time slows down by the lack of food. Biological mechanism inhibits
reproduction of the young that are not able to get food for survival that is for the good growth and right
development. This mechanism works vice versa: the reproduction potential comes to the fore when
there is plenty of food.
The data from the European Bison Pedigree Book (EBPB) were used to analyse the natality of the
European Bison in Romania. There were examined the total European Bison number, the gender ratio
with number of born calves. The gender ratio of new-born calves was also analysed.
There were 1.684 Eurpean Bison in Romania at the observed period of time. 912 of it were females
(54,16%), and the rest of population were males (45,44%). The females number for the year of 2019 is
not complete, and in the official EBPB document for the Armenis Forest, where European Bison live
in the wild, females and males number is not indicated at all. Based on these incomplete data, the
proportion of male calves is 55,07% and female calves is 44.93%.
Key words: European Bison, reproduction, population, natality rate.
