The largest center of the whole region is the town of
Vlasotince, but in general, the area is one of the least developed in Serbia, very poor and extremely depopulating. For example, the population of the
Crna Trava municipality decreased from around 14,000 in 1953 to only 2,500 in 2002. Accordingly, the density also dropped from 43 per km² in 1953 to only 8 per km² in 2002. A circular freeway connects the valleys of the Vlasina and Južna Morava rivers. In 2005 Hellenic Bottling Co., a subsidiary of The Coca-Cola Company, bought the local water factory ("Rosa" is a trademark for this water) which is located close to the Vlasina source thus causing protests of the local environmentalists. Activists from the "Eco base South" (Eko baza Jug) were afraid of
overexploitation drying out the sources of the river. == Wildlife ==
