Abstract: - The monitoring of forest coverage changes according to the remote sensing indices in the the Mociar Forest. The development level of the Mociar Forest between 1986 and 2016 was measured using remote sensing techniques, by developing geographical tests based on the NDVI value, during distinctive timeframes backed up by LANDSAT satellite images that cover the specific timeframe of analysis. This underlined the changes occurred in the forest lots of the Mociar Forest, changes related to the anthropic influence, the distress caused by the climate variations (temperature, rainfall) and also due to the edaphic factors (excess of soil humidity, variations of nutrient levels). In order to identify the impact of the climate factors, especially the rainfall levels pertaining to the analyzed timeframe, the value of the Angot index number was established, which enabled the monthly framing according to the specific rainfall class. This helped pinpoint the forest areas where the drying of the forest vegetation has extended, the result being useful in the monitoring process of the Mociar Forest.
