So, for example, the specialists of the Nature State Reserve Bryanskyi Forest, where we release the bear cubs in order to restore the disappearing local population, registered not an once the bears with the ear tags, and, in particular, female bear with offspring. Due to releases of the young bear cubs, the local brown bear population was restored and till now is stable.
We use when possible radio and collar tags, battery life of which ranges from half a year – 2,5 years. It allowed us to follow the fate of the young bears up to the age 1,5 – 2,5 years. It turned to be that the young animals could cover 100 km and eve more from the release site. As well we received the data about the time of entering the den and leaving it after a successful wintering.
Cameratraps are also very important means of monitoring. So for example, on the territories, adjacent to the OBRC, we registered during 7 years the female bear Nora born 2008 – during this period she brought three offspring with three bear cubs in each.
In 2017 the specialists of the Central Forest Nature Reserve due to the cameratrap received the pictures of the released by OBRC female bear with the ear tag and with a bear cub.
Considering that bears are wary of humans, and it is nearly impossible to see a bear in natur, these data are very valuable!
