Abstract:
At the moment, the disruptions (mainly negative ones) in the social &economic systems have fewer short-term solutions, and the medium and longterm ones disregard the greater sustainable development at micro, meso and macrolevels. The economic and financial losses registered in such eco-systems, affected by disruptions of their stability and integrity, lead, in most cases, to major climate changes, especially at regional level and in the local zones, with unexpected, diverse and sometimes irreversible implications for the ecological environment. A quantifiable value for such losses, which are both quantitative and qualitative, in a specific case (the losses in terms of Norway spruce, Picea abies, forests affected by biotic and abiotic factors in the Bargau Mountains) may provide new approach methods. This is the view which interests us: the economic and financial losses may be quantifiable in terms of effects of the disruptions caused, a ‘snowball’ effect, with larger damages (losses) in the adjacent zones or downstream of the Bargau Mountains (a situation that can be generalised). Forest ecosystems are affected quantitatively by several destabilizing factors, in particular due to the action of wind and snow and the quality of the wounds caused by the large game, by way of a decrease in the wood (bears, deer). Three of the four ecosystems are located in the Management Units (working circle)II Iliuta from the Tihuta-Colibita RA Forest District, in the sub-divisions: 75 C and 662 B, for which research has been conducted on the 60 year-oldecosystem, and 363 D, where the ecosystem is 120 years old.
