Fig. 1From: Decreasing stand density favors resistance, resilience, and recovery of Quercus petraea trees to a severe drought, particularly on dry sitesSummer water balance (HBs) anomalies from 1997 to 2012 for each HBc (wet, mesic and dry; mean values in mm in parenthesis). The HBs was calculated as the sum from June to August (in mm). Negative values correspond to conditions drier than normal (wetter otherwise). Wet, Parroy; mesic, mean for Grosbois and Réno-Valdieu; dry, Montrichard. See text for detailsBack to article page
