Mountain Goc is one of the regions with the highest water potential in Central Serbia (Yugoslavia), with specific annual runoff of 12-17 l/s per square km. Upper part of the catchment area of the Gvozdacka River has 111 springs, on the surface of 13.3 square km. 33 springs has volume yield from 0.5 to 2.5 l/s, with physical and chemical parameters of high water quality. These springs never dry up, even during years with low amount of precipitation. The upper part of the catchment area of the Gvozdacka River is under association Abieti-Fagetum, which is one of the worthiest in Serbia (Yugoslavia). Besides annual amount of precipitation, characteristics of soil, hydro-geological attributes of rock masses, influence of vegetation on processes of interception and evapotranspiration, which are very important factors for preservation of springs and their volume yield, also the system of forest ecosystems management. Not adequate measures in exploitation of forests lead to decreasing of volume yield of springs, and often to their disappearing.

Sustainable usage of forest ecosystems in Serbia [Serbia&Montenegro] from aspects of water supply and erosion control
2003

Forest ecosystems are important component of environment and row basis for wood processing industry. Traditional attitude about primate of productive functions in relation to useful functions, is under question, due to next reasons: exhaustion of sources of wood mass; affirmation of protective and regulative functions in domains of water-supply and erosion control. This attitide os represented in basic plan documents in Serbia, as well as in European Union. Protection, care of existing, and restoration of degraded forests, are the possibilities for development of high-profitable activities such as: recreation and sport tourism, hunting tourism and healthy food production.
