fishery. The plants are old, from the first half of the 20th century. In some parts canyon like-structures (like inverse valley slopes at Gradištanski canyon) were formed by the river. The gorge itself carved through the Kunovica plateau between the southern slopes of the Mountains of Svrljig and the mountain of Suva Planina, and the surrounding areas are known for their high-quality vineyards. There is also a large Ostrovica quarry in the gorge, where six villages are located, the largest one being Sićevo that gives the name to the whole gorge. Wildlife The Oblik rise, above the Sićevo gorge, is a location where extremely rare plants Serbian ramonda and Natalie's ramonda can be found. Trouts can be find on the entire river's course, with their number varying over the years. Over 100 bird species live only in the gorge section, including golden eagle. Human history North of the river, in the Sićevo gorge, excavations in the Mala Balanica cave began in 2005. Mousterian stone tools from the Middle Paleolithic were discovered until 2009. Numerous animal remains were discovered in the same layer, up to deep. A hominid mandible was discovered at the depth of in 2007. It is concluded that it belongs to a young adult person, though the sex can't be specified. Originally believed to be 200,000 to 300,000 years old, during the 2013 examination of the remains it was estimated that the lower jaw was not younger than 397,000 years, and probably older than 525,000 years, which makes it one of the oldest discovered remains of the Homo heidelbergensis in Europe. Later, only further from this finding, remains of Neanderthals were discovered. Four teeth belonged to one adult and one child, and are estimated to be 300,000 years old. It was suggested that some kind of contact of different species of humans happened in the region, one group being from Europe, and the other coming from Asia Minor. On the southern side of the river, on the Suva Planina, there is a Pešturina cave, nicknamed the "Serbian Atapuerca". Artifacts from the Middle and Upper Paleolithic were discovered since the archaeological excavations began in 2006. The remains, identified as the Mousterian culture, were dated from 102,000 BP+ 5,000 to 39,000 BP + 3,000, which makes Pešturina one of the latest surviving Neanderthal habitats. In April 2019 it was announced that the remains of the Neanderthal man have been discovered.
