Abstract

This study aims to identify the changes that occurred, quality-wise, in the past 2 decades (1990–2011) in forest vegetation in Southwestern Romania, and to establish the link between those changes and extant thermal stress in the region. First the temperature and precipitation parameters from 3 weather stations were used; these parameters were analyzed both individually and as aridity indexes. Then, NDVI indexes were used and analyzed, starting off from Landsat satellite images, acquired in 1990, 2000 and 2011. Statistical correlations were established between the peak values of average annual temperatures, represented in space, and negative changes in the NDVI index, as revealed by the change-detection analysis. The results obtained indicated there is a statistically significant connection between thermal stress and the desiccation (degradation) of forest species in the analyzed area, with false acacia (Robinia Pseudoacacia) the main species to be impacted
