they began causing damage to local orchards and apiaries but have not attacked livestock nor the villagers. Some of the animals are tracked via satellite. The tracking shows that females, especially with cubs, occupy a compact area, but males range more widely travelling west, crossing the Drina into Bosnia where hunting is permitted. The bears do not tend to travel into central Serbia, to the east or northeast of the mountain, but the first animal which was tracked used to go all the way to the slopes of the Kopaonik mountain, in the southeast. In April 2019 there were some 60 bears on the Tara, making 80% of the entire brown bear population in Serbia. In the fall of 2021, a 15-year-old bear named Aleksandar (after Alexander the Great) was equipped with the GPS collar camera. He was specifically selected due to his massive size, as he weighed around . Footage until August 2022, when he managed to tear the collar, proved that he indeed was an alpha bear on the mountain. Aleksandar was hibernating from mid-November to late March and was quite reluctant to leave the cave. Other animals were hiding from him and moving out of his way so much, that he had no encounters with other animals than bears. He was feeding at the mangers and "enjoyed" spending time with two she-bears in this period, but he mostly was just calmly wandering all over. The bear avoided open spaces, not crossing over the forests' rims. He was extremely cautious to avoid humans, even when close to the villages. History Work published in May 2018 in the Proceedings of the National Academy of Sciences of the United States of America journal by the research team from the Northumbria University revealed that the locality "Crveni Tepih" shows the evidence of the oldest lead pollution in Europe. It is dated to 3600 BC, predating the previous oldest findings dated to 3000 BC in southern Spain and pushed back the origins of lead metallurgy for six centuries. Locality Kremenilo, near the village of Višesava, is a prehistoric settlement, dated between 5000 and 7000 BC, as part of the Starčevo culture which developed in Podunavlje as the first agricultural culture in the Balkans. Mountainous Illyrian tribe of Autariatae inhabited the area during the Bronze Age. Though it is often mentioned that tara means "star" in Sanskrit, name of the mountain is derived
