• Resumen

  • A survey of 92 vineyards, representing 10 winegrowing regions in south-eastern Australia, soon after exposure to a severe heatwave, revealed variation in the reported heat-related impact. This variation was observed between regions, within regions and within vineyards. Notably the estimates of losses were not always related to the amount of heat above a certain threshold but to the management practices employed in the lead-up and through the event. Applicable and achievable recommendations for managing severe heat events have resulted from this assessment. We believe this method of capturing information from the diverse knowledge-base of managers is a very effective way to reveal potential adaptive capacity to a changing climate.
