Sažetak
Mediterranean forest ecosystems in Croatia are of very high significance because of ecological functions they provide. Mediterranean forests are, besides of its multiple goods and services largely related to their environmental and social functions. The risk of impacts of air pollution, erosion, landslides and floods is being so high in this region. These risk factors combined with climate change are likely to affect nutrient turnover and nutrient availability, soil moisture and, ultimately, growth and primary productivity. These forest ecosystems cover almost half of Croatian total forest area. They are under the combined influence of local, regional and long-distance pollution sources. The atmospheric deposition and its transformation in contact with vegetation are of great importance in understanding its effects on forests. It has an impact on forest ecosystem through eutrophication by nitrogen and soil acidification, altering soil properties and processes. Changes in the soil chemistry may lead to imbalances in the nutrient supply and subsequently to unbalanced nutrition of the trees. Fluxes of nutrients, contaminants and other elements within forest ecosystems are important indicators of ecosystem functioning and stability. Important fluxes include uptake by plants, fluxes associated with soil processes, and leaching into surface waters and ground waters. The conversion of precipitation to groundwater is reduced by the interception of forests and by evaporation from the tree canopy. It is reduced further through transpiration of soil moisture from foliage. These can be described as losses to the useful water system in forest. The changes in tree growth and crown condition, in most cases, are a result of a multitude of stress factors including atmospheric inputs and rapidly changing climatic condition. In order to fill in the knowledge gap, the monitoring plots are set up in different Mediterranean forests ecosystems and intensive environmental monitoring has been organized. Based on the obtained data we will estimate the impact of acid and nutrient deposition on nutritional status of soil and foliage, water availability, tree crown condition and growth as well as the cause-effect relationships between the health status of forest ecosystems and natural and anthropogenic factors.
