Change over time in vegetation communities in burnt plots relative to unburnt controls as measured by the first axis of a principal response curve (PRC) for a Undrained quadrats and b Drained quadrats. Species with the highest scores (i.e., corresponding to the largest response to the time × site interaction) are shown on the vertical axis, species with an absolute value > 0.5 are in bold red character, as they represent species most associated with the time × treatment trend displayed
