Soil parameters for each site, with error bars showing standard error; a) percentage mass lost on ignition (LOI), b) % water loss, c) pH, d) plant available phosphorus, e) carbon to nitrogen ratio (C:N). Statistical significance was calculated using a Kruskal-Wallis followed by a post hoc test using the criterium Fisher’s least significant difference (LSD) to determine where the difference lies, signified by lowercase letters above the bars. Within each graph, all bars which share letters are not significantly different from each other. Data are mean +/− standard errors. pH, n = 9; C:N n = 9; % water loss mean, n = 6; % loss on ignition mean, n = 6; plant available phosphorus mean, n = 3 except for EDB and ESB where n = 9
