Highlighting the Economic and Financial Losses in Ecosystems, with Special Reference to the Forest Ecosystems of the Bârgău Mountains

Currently, disruptions-particularly negative ones-within social and economic systems lack effective short-term solutions, while medium- and long-term strategies often neglect sustainable development across micro, meso, and macro levels. These instabilities generate significant economic and financial losses, which frequently contribute to climate change, especially at regional and local scales. Such impacts are observable in forest ecosystems, where disturbances can cause diverse and sometimes irreversible ecological consequences. his study examines quantifiable losses in Norway spruce (Picea abies) forests affected by biotic and abiotic stressors in the Bârgău Mountains, Romania. Research was conducted in three forest ecosystems located in Management Unit Il Iliuta of the Tihuța-Colibița Forest District, in compartments 75C and 662B (60-year-old stands), and 363D (120-year-old stand). The methodology included field observation, controlled experiments, and statistical analysis. Results indicate that these ecosystems are significantly affected by destabilizing factors such as windthrow and snow damage, as well as quality degradation caused by large game (e.g., bears, deer), which reduces timber value. In conclusion, the economic and ecological impacts of these disruptions can be quantified. The observed "snowball effect" suggests that damages extend beyond the immediate area, affecting adjacent and downstream ecosystems-an outcome with broader implications for regional forest management and climate resilience.
