temperature ranges were lower in Holm oak forest stand than in garrigue and Aleppo pine forest stands. In the garrigue degradation stages, range of annual air temperature was 40.25 °C, higher than other types of forest stands. The range of soil temperature in garrigue was 21.30 °C. The highest annual range of relative air humidity (81.31%) was in the maquis. The lowest annual range of relative air humidity was in Holm oak forest (77.25 %). The annual range of volumetric soil moisture was highest in garrigue, 82.80% (Figure 2, 3). The highest mean air temperature (17.98 °C, p < 0.0000, MS = 0.08, df = 150.00) and soil temperature (18.09 °C, p < 0.0000, MS = 1.16, df = 147.00) were measured in the garrigue. The lowest mean air temperature (15.81 °C) and soil temperature (15.52 °C) were in maquis (Figure 4). The highest mean relative air humidity was measured in the Holm oak forest (72.59%), and the highest mean volumetric soil moisture was measured in maquis (14.28%). The air temperature (p < 0.0000, MS = 0.08, df = 150.00), relative air humidity (p = 0.0000, MS = 9.52, df = 150.00), soil temperature (p = 0.0000, MS = 1.16, df = 147.00), volumetric soil moisture (p < 0.0000, MS = 5.21, df = 147.00), precipitation (p = 0.0000, MS = 66.22, df = 60.00), potential evapotranspiration (p < 0.0000, MS = 0.44, df = 60.00), and dry season water deficit (p = 0.0001, MS = 24.08, df = 42.00) differed significantly between the degradation stages of garrigue and maquis (Figures 3 and 4). We found significant difference between the mean air temperatures in the Holm oak forest versus the maquis stage (p < 0.0000, MS = 0.08, df = 150.00). The mean values of soil temperature (p = 0.0000, MS = 5.21, df = 147.00), relative air humidity (p = 0.0000, MS = 9.52, df = 150.00), precipitation (p = 0.0000, MS = 66.29, df = 60.00), and potential evapotranspiration (p = 0.0001, MS = 0.44, df = 60.00) were higher in the stands of Holm oak in comparison to in the maquis degradation stage. Significant differences were found between the stands of Holm oak and Aleppo pine in the values of air temperature (p < 0.0042, MS = 0.08, df = 150.00), relative air humidity (p = 0.0000, MS = 9.52, df = 150.00), soil temperature (p < 0.0001, MS = 1.16, df = 147.00), volumetric soil moisture (p < 0.0121, MS = 5.21, df = 147.00), precipitation (p < 0.0004, MS = 66.29, df = 60.00), potential evapotranspiration (p < 0.0000, MS = 0.44, df = 60.00), and dry season water deficit (p < 0.0004, MS = 24.08, df = 42.00). The highest average precipitation (77.93 mm, p < 0.0000, MS = 66.29, df = 60.00) and potential evapotranspiration (89.15 mm, p < 0.0000, MS = 0.44, df = 60.00) were in the garrigue degradation stage. The lowest average precipitation (51.95 mm, p < 0.0000) and potential evapotranspiration (83.79 mm, p < 0.0000) were in the maquis stage. The mean dry season (summer) water deficit was highest in the garrigue |
