Forest vegetation-climate feedback regimes are designated based on the temporal correlations between the forest vegetation and the surface temperature and precipitation. The climate system responds in complex ways to changes in forcing that may be natural or human-induced and climate-induced changes at the forest land surface may in turn feedback on the climate itself through changes in soil moisture, vegetation, radiative characteristics, and surface-atmosphere exchanges of water vapor. The climate of the Carpathians is moderately cool and humid, with both temperature and precipitation strongly correlated with elevation. Extreme climatic events and anthropogenic effects have a strong impact on forest ecosystem. The spatio-temporal dynamics are assessed in terms of the NDVI-surface temperature correlations. Observed vegetation feedbacks on temperature and precipitation are assessed based on Landsat TM, ETM satellite data across the test mountain forest areas in Prahova Valley, Romania for period 1989 -2009. Specific aim of this paper is to assess the forest vegetation-climate feedbacks on mountain forest ecosystem and its biodiversity as well as on adjacent environment areas and to provide early warning strategies on the remote sensing spectral information basis.
