The aim of this work is to study the possible effect of slope on post fire vegetation recovery. The experimental area is located in a hilly area of north-western Sardinia. The climate is characterized by water deficit conditions occurring from May through September and precipitation events mainly concentrated in autumn and winter. The area is covered by Quercus suber and Mediterranean shrubs and it was burned by wildfires that swept through the area in August 2013. The fire burned an area of 28 ha and was characterized by a moderate fire severity. Immediately after fire two areas characterized by different slopes (20% and 30%) were selected and ten 30 m2 plots were installed. Percentage of vegetation cover was measured 1, 6 and 18 months after the fire by the line intercept method. In addition, ground cover ocular estimation (percentage of herbaceous, bare soil and stoniness surface) were made using a 1 m2 point frame with wire intersections at 10 cm intervals with 3 repetitions per plot. The data were statistically treated to analyze the effects of slope on vegetation recovery.

Abstract
The aim of this work is to study the possible effect of slope on post fire vegetation recovery. The experimental area is located in a hilly area of north-western Sardinia. The climate is characterized by water deficit conditions occurring from May through September and precipitation events mainly concentrated in autumn and winter. The area is covered by Quercus suber and Mediterranean shrubs and it was burned by wildfires that swept through the area in August 2013. The fire burned an area of 28 ha and was characterized by a moderate fire severity. Immediately after fire two areas characterized by different slopes (20% and 30%) were selected and ten 30 m2 plots were installed. Percentage of vegetation cover was measured 1, 6 and 18 months after the fire by the line intercept method. In addition, ground cover ocular estimation (percentage of herbaceous, bare soil and stoniness surface) were made using a 1 m2 point frame with wire intersections at 10 cm intervals with 3 repetitions per plot. The data were statistically treated to analyze the effects of slope on vegetation recovery.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
